    Opinion by Chief Judge Thomas
    SUMMARY**
    Standing / Privacy Law
    The panel affirmed the district court’s dismissal of the
    Stored Communications Act (“SCA”), breach of contract, and
    breach of implied covenant claims; reversed the dismissal of
    the remaining claims; and remanded for further consideration,
    in an action alleging privacy-related claims against Facebook,
    Inc.
    Facebook uses plug-ins to track users’ browsing histories
    when they visit third-party websites, and then complies these
    browsing histories into personal profiles which are sold to
    advertisers to generate revenue. Plaintiffs filed an amended
    complaint on behalf of themselves and a putative class of
    people who had active Facebook accounts between May 27,
    2010 and September 26, 2011. They alleged that Facebook
    executives were aware of the tracking of logged-out users and

    recognized that these practices posed various user-privacy
    issues.
    As an initial matter, the panel held that plaintiffs had
    standing to bring their claims. Specifically, the panel held
    that plaintiffs adequately alleged an invasion of a legally
    protected interest that was concrete and particularized.
    As to the statutory claims, the panel held that the
    legislative history and statutory text demonstrated that
    Congress and the California legislature intended to protect
    these historical privacy rights when they passed the Wiretap
    Act, SCA, and the California Invasion of Privacy Act
    (“CIPA”). In addition, plaintiffs adequately alleged that
    Facebook’s tracking and collection practices would cause
    harm or a material risk to their interest in controlling their
    personal information. Accordingly, plaintiffs sufficiently
    alleged a clear invasion of their right to privacy, and plaintiffs
    had standing to pursue their privacy claims under these
    statutes.
    As to plaintiffs’ alleged theories of California common
    law trespass to chattels and fraud, statutory larceny, and
    violations of the Computer Data Access and Fraud Act, the
    panel held that plaintiffs sufficiently alleged a state law
    interest whose violation constituted an injury sufficient to
    establish standing to bring their claims. Because California
    law recognizes a legal interest in unjustly earned profits,
    plaintiffs adequately pled an entitlement to Facebook’s profits
    from users’ data sufficient to confer Article III standing.
    Plaintiffs also sufficiently alleged that Facebook profited
    from this valuable data.
    4    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    Turning to the merits, the panel held that plaintiffs
    adequately stated claims for relief for intrusion upon
    seclusion and invasion of privacy under California law. First,
    the panel held that in light of the privacy interests and
    Facebook’s allegedly surreptitious and unseen data collection,
    plaintiffs adequately alleged a reasonable expectation of
    privacy to survive a Fed. R. Civ. P. 12(b)(6) motion to
    dismiss. Second, plaintiffs identified sufficient facts to
    survive a motion to dismiss on the ultimate question of
    whether Facebook’s tracking and collection practices could
    highly offend a reasonable individual.
    The panel held that plaintiffs sufficiently alleged that
    Facebook’s tracking and collection practices violated the
    Wiretap Act and CIPA. Both statutes contain an exemption
    from liability for a person who is a “party” to the
    communication. Noting a circuit split, the panel adopted the
    First and Seventh Circuits’ understanding that simultaneous
    unknown duplication and communication of GET requests
    did not exempt Facebook from liability under the party
    exception. The panel concluded that Facebook was not
    exempt from liability as a matter of law under the Wiretap
    Act or CIPA, and did not opine whether plaintiffs adequately
    pleaded the other requisite elements of the statutes.
    The panel held that the district court properly dismissed
    plaintiffs’ claims under the SCA, which required plaintiffs to
    plead that Facebook gained unauthorized access to a
    “facility” where it accessed electronic communications in
    “electronic storage.” The panel agreed with the district
    court’s determination that plaintiffs’ data was not in
    electronic storage. The panel concluded that plaintiffs’
    claims for relief under the SCA were insufficient.
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.              5
    The panel held that the district court properly dismissed
    plaintiffs’ breach of contract claim for failure to state a claim.
    Plaintiffs alleged that Facebook entered into a contract with
    each plaintiff consisting of the Statement of Rights and
    Responsibilities, Privacy Policy, and relevant Help Center
    pages. The panel held that plaintiffs failed to adequately
    allege the existence of a contract that was subject to breach.
    The panel also held that the district court properly dismissed
    plaintiffs’ claim that Facebook’s tracking practices violated
    the implied covenant of good faith and fair dealing, where the
    allegations did not go beyond the asserted breach of contract
    theories.

    OPINION
    THOMAS, Chief Judge:
    In this appeal, we are asked to determine whether:
    (1) Facebook-users Perrin Davis, Brian Lentz, Cynthia Quinn,
    and Mathew Vickery (“Plaintiffs”) have standing to allege
    privacy-related claims against Facebook, and (2) Plaintiffs
    adequately allege claims that Facebook is liable for common
    law and statutory privacy violations when it tracked their
    browsing histories after they had logged out of the Facebook
    application. We have jurisdiction pursuant to 
    28 U.S.C. § 1291
    . We affirm in part; reverse in part; and remand for
    further proceedings.
    I
    Facebook uses plug-ins1 to track users’ browsing histories
    when they visit third-party websites, and then compiles these
    browsing histories into personal profiles which are sold to
    advertisers to generate revenue. The parties do not dispute
    that Facebook engaged in these tracking practices after its
    users had logged out of Facebook.
    1
    A plug-in is a program that extends the functionality of an existing
    program, such as an internet browser.
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.                 7
    Facebook facilitated this practice by embedding third-
    party plug-ins on third-party web pages. The plug-ins, such
    as Facebook’s “Like” button, contain bits of Facebook code.
    When a user visits a page that includes these plug-ins, this
    code is able to replicate and send the user data to Facebook
    through a separate, but simultaneous, channel in a manner
    undetectable by the user.
    As relevant to this appeal, the information Facebook
    allegedly collected included the website’s Uniform Resource
    Locator (“URL”) that was accessed by the user. URLs both
    identify an internet resource and describe its location or
    address. “[W]hen users enter URL addresses into their web
    browser using the ‘http’ web address format, or click on
    hyperlinks, they are actually telling their web browsers (the
    client) which resources to request and where to find them. In
    re Zynga Privacy Litig., 
    750 F.3d 1098
    , 1101 (9th Cir. 2014).
    Thus, the URL provides significant information regarding the
    user’s browsing history, including the identity of the
    individual internet user and the web server, as well as the
    name of the web page and the search terms that the user used
    to find it. In technical parlance, this collected URL is called
    a “referer header” or “referer.” Facebook also allegedly
    collected the third-party website’s Internet Protocol (“IP”)
    address,2 which reveals only the owner of the website.
    Facebook allegedly compiled the referer headers it
    collected into personal user profiles using “cookies”—small
    text files stored on the user’s device. When a user creates a
    Facebook account, more than ten Facebook cookies are
    2
    An “IP address” is a numerical identifier for each computer or
    network connected to the Internet. hiQ Labs, Inc. v. LinkedIn Corp., 
    938 F.3d 985
    , 991 n.4 (9th Cir. 2019).

    placed on the user’s browser. These cookies store the user’s
    login ID, and they capture, collect, and compile the referer
    headers from the web pages visited by the user. As most
    relevant to this appeal, these cookies allegedly continued to
    capture information after a user logged out of Facebook and
    visited other websites.
    Plaintiffs claim that internal Facebook communications
    revealed that company executives were aware of the tracking
    of logged-out users and recognized that these practices posed
    various user-privacy issues. According to the Plaintiffs,
    Facebook stopped tracking logged-out users only after
    Australian blogger Nik Cubrilovic published a blog detailing
    Facebook’s tracking practices.3
    Plaintiffs filed a consolidated complaint on behalf of
    themselves and a putative class of people who had active
    Facebook accounts between May 27, 2010 and September 26,
    2011. After the district court dismissed their first complaint
    with leave to amend, Plaintiffs filed an amended complaint.
    In the amended complaint, they alleged a number of claims.
    The claims relevant to this appeal consist of: (1) violation of
    the Wiretap Act, 
    18 U.S.C. § 2510
    , et seq.; (2) violation of
    the Stored Communications Act (“SCA”), 
    18 U.S.C. § 2701
    ;
    (3) violation of the California Invasion of Privacy Act
    (“CIPA”), 
    Cal. Pen. Code §§ 631
    , 632; (4) invasion of
    privacy; (5) intrusion upon seclusion; (6) breach of contract;
    (7) breach of the duty of good faith and fair dealing; (8) civil
    3
    The blog post quickly gained notoriety and played a role in a lawsuit
    that alleged multiple counts of deceptive trade practices brought against
    Facebook by the Federal Trade Commission. In the Matter of Facebook
    Inc., FTC File No. 0923184. Facebook reached a settlement with the FTC
    in November 2011.
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.           9
    fraud; (9) trespass to chattels; (10) violations of California
    Penal Code § 502 Computer Data Access and Fraud Act
    (“CDAFA”); and (11) statutory larceny under California
    Penal Code §§ 484 and 496.
    The district court granted Facebook’s motion to dismiss
    the amended complaint. First, the district court determined
    that Plaintiffs had failed to show they had standing to pursue
    claims that included economic damages as an element, thus
    disposing of the claims for trespass to chattels, violations of
    the CDAFA, fraud, and statutory larceny. It dismissed these
    claims without leave to amend.
    The district court also dismissed for failure to state a
    claim, without leave to amend, Plaintiffs’ claims for
    violations of the Wiretap Act, CIPA, and the SCA, as well as
    their common law claims for invasion of privacy and
    intrusion upon seclusion. The district court dismissed the
    claims for breach of contract and the breach of the implied
    covenant of good faith and fair dealing, but granted leave to
    amend these claims. In response, Plaintiffs amended their
    complaint as to the breach of contract and implied covenant
    claims. The district court subsequently granted Facebook’s
    motion to dismiss the amended claims. This timely appeal
    followed.
    We review de novo a district court’s determination of
    whether a party has standing. San Luis & Delta-Mendota

    672 F.3d 676

    claim under Rule 12(b)(6). Dougherty v. City of Covina,

    , 897 (9th Cir. 2011).

    II
    The Plaintiffs have standing to bring their claims.
    “Where standing is raised in connection with a motion to
    dismiss, the court is to ‘accept as true all material allegations
    of the complaint, and . . . construe the complaint in favor of
    the complaining party.’” Levine v. Vilsack, 
    587 F.3d 986
    ,
    991 (9th Cir. 2009) (quoting Thomas v. Mundell, 
    572 F.3d 756
    , 760 (9th Cir. 2009)).
    To establish standing, a “[p]laintiff must have (1) suffered
    an injury in fact, (2) that is fairly traceable to the challenged
    conduct of the defendant, and (3) that is likely to be redressed
    by a favorable judicial decision.” Spokeo v. Robins, __ U.S.
    __, 
    136 S. Ct. 1540
    , 1547 (2016). To establish an injury in
    fact, a plaintiff must show that he or she suffered “an invasion
    of a legally protected interest” that is “concrete and
    particularized.” 
    Id. at 1548
     (quoting Lujan v. Defs. of
    Wildlife, 
    504 U.S. 555
    , 560 (1992)). A particularized injury
    is one that affects the plaintiff in a “personal and individual
    way.” Id.; see also Dutta v. State Farm Mutual Auto. Ins.
    Co., 
    895 F.3d 1166
    , 1173 (9th Cir. 2018).
    A concrete injury is one that is “real and not abstract.”
    Spokeo, 
    136 S.Ct. at 1548
     (internal quotation marks omitted).
    Although an injury “must be ‘real’ and ‘not abstract’ or
    purely ‘procedural’ . . . it need not be ‘tangible.’” Dutta,
    895 F.3d at 1173. Indeed, though a bare procedural violation
    of a statute is insufficient to establish an injury in fact,
    Congress may “elevat[e] to the status of legally cognizable
    injuries concrete, de facto injuries that were previously
    inadequate” to confer standing. Spokeo, 
    136 S. Ct. at 1549
    (quoting Lujan, 
    504 U.S. at 578
    ).
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 11
    To determine whether Congress has done so, we ask
    whether: (1) “Congress enacted the statute at issue to protect
    a concrete interest that is akin to a historical, common law
    interest[,]” and (2) the alleged procedural violation caused
    real harm or a material risk of harm to these interests. Dutta,
    895 F.3d at 1174.
    A
    The district court properly concluded that Plaintiffs had
    established standing to bring claims for invasion of privacy,
    intrusion upon seclusion, breach of contract, breach of the
    implied covenant of good faith and fair dealing, as well as
    claims under the Wiretap Act and CIPA, because they
    adequately alleged privacy harms.
    Plaintiffs have adequately alleged an invasion of a legally
    protected interest that is concrete and particularized.
    “[V]iolations of the right to privacy have long been
    actionable at common law.” Patel v. Facebook, 
    932 F.3d 1264
    , 1272 (9th Cir. 2019) (quoting Eichenberger v. ESPN,
    Inc., 
    876 F.3d 979
    , 983 (9th Cir. 2017)). A right to privacy
    “encompass[es] the individual’s control of information
    concerning his or her person.” Eichenberger, 876 F.3d at 983
    (quoting U.S. Dep’t of Justice v. Reporters Comm. for
    Freedom of the Press, 
    489 U.S. 749
    , 763 (1989)).
    As to the statutory claims, the legislative history and
    statutory text demonstrate that Congress and the California
    legislature intended to protect these historical privacy rights
    when they passed the Wiretap Act, SCA, and CIPA. See S.
    REP. NO. 99-541, at 2 (1986) (“[The Wiretap Act] is the
    primary law protecting the security and privacy of business
    and personal communications in the United States today.”);
    12 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    Id. at 3 (“[The SCA] is modeled after the Right to Financial
    Privacy Act, 
    12 U.S.C. § 3401
     et seq. to protect privacy
    interests in personal and proprietary information . . . .”); 
    Cal. Pen. Code § 630
     (noting that CIPA was passed “to protect the
    right of privacy of the people of this state”). Thus, these
    statutory provisions codify a substantive right to privacy, the
    violation of which gives rise to a concrete injury sufficient to
    confer standing. See Campbell v. Facebook, Inc., —F.3d—,
    
    2020 WL 1023350
    , at *7–8 (9th Cir. Mar. 3, 2020).
    Plaintiffs have adequately alleged harm to these privacy
    interests. Plaintiffs alleged that Facebook continued to
    collect their data after they had logged off the social media
    platform, in order to receive and compile their personally
    identifiable browsing history. As alleged in the complaint,
    this tracking occurred “no matter how sensitive” or personal
    users’ browsing histories were.         Facebook allegedly
    constantly compiled and updated its database with its users’
    browsing activities, including what they did when they were
    not using Facebook. According to Plaintiffs, by correlating
    users’ browsing history with users’ personal Facebook
    profiles—profiles that could include a user’s employment
    history and political and religious affiliations—Facebook
    gained a cradle-to-grave profile without users’ consent.
    Here, Plaintiffs have adequately alleged that Facebook’s
    tracking and collection practices would cause harm or a
    material risk of harm to their interest in controlling their
    personal information. As alleged, Facebook’s tracking
    practices allow it to amass a great degree of personalized
    information. Facebook’s user profiles would allegedly reveal
    an individual’s likes, dislikes, interests, and habits over a
    significant amount of time, without affording users a
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 13
    meaningful opportunity to control or prevent the unauthorized
    exploration of their private lives.
    “[A]dvances in technology can increase the potential for
    unreasonable intrusions into personal privacy.” Patel,
    932 F.3d at 1272. As the Third Circuit has noted, “[i]n an era
    when millions of Americans conduct their affairs increasingly
    through electronic devices, the assertion . . . that federal
    courts are powerless to provide a remedy when an internet
    company surreptitiously collects private data . . . is untenable.
    Nothing in Spokeo or any other Supreme Court decision
    suggests otherwise.” In re Google Inc. Cookie Placement
    Consumer Privacy Litig., 
    934 F.3d 316
    , 325 (3rd Cir. 2019)
    (“In re Google Cookie”).
    Accordingly, Plaintiffs have sufficiently alleged a clear
    invasion of the historically recognized right to privacy.
    Therefore, Plaintiffs have standing to pursue their privacy
    claims under the Wiretap Act, SCA, and CIPA, as well as
    their claims for breach of contract and breach of the implied
    covenant of good faith and fair dealing.
    B
    Plaintiffs also alleged theories of California common law
    trespass to chattels and fraud, statutory larceny, and
    violations of the CDAFA. The district court dismissed these
    claims for lack of standing, concluding that the Plaintiffs
    failed to demonstrate that they had suffered the economic
    14 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    injury the district court viewed as necessary to bring each of
    these claims.4 We respectfully disagree.
    Plaintiffs allege that Facebook is unjustly enriched
    through the use of their data. Facebook argues that unjust
    enrichment is not sufficient to confer standing, and that
    Plaintiffs must instead demonstrate that they either planned
    to sell their data, or that their data was made less valuable
    through Facebook’s use. They similarly assert that Plaintiffs’
    entitlement to damages does not constitute an injury for
    purposes of standing.
    However, “state law can create interests that support
    standing in federal courts.” Cantrell v. City of Long Beach,
    
    241 F.3d 674
    , 684 (9th Cir. 2001). As relevant here,
    California law recognizes a right to disgorgement of profits
    resulting from unjust enrichment, even where an individual
    has not suffered a corresponding loss. See Cty. of San
    Bernardino v. Walsh, 
    158 Cal. App. 4th 533
    , 542 (2007)
    (noting that where “a benefit has been received by the
    defendant but the plaintiff has not suffered a corresponding
    loss, or in some cases, any loss, but nevertheless the
    enrichment of the defendant would be unjust . . . [t]he
    defendant may be under a duty to give to the plaintiff the
    4
    To prevail on a claim for trespass to chattels, Plaintiffs must
    demonstrate that some actual injury may have occurred and that the owner
    of the property at issue may only recover the actual damages suffered as
    a result of the defendant’s actions. Intel Corp. v. Hamidi, 
    30 Cal. 4th 1342
    , 1351–52 (2003). Fraud similarly requires damages, Beckwith v.
    Dahl, 
    205 Cal. App. 4th 1039
    , 1064 (2012), as does a violation of the
    CDAFA, Mintz v. Mark Bartelstein & Assocs., 
    906 F. Supp. 2d 1017
    ,
    1032 (C.D. Cal. 2012) (noting that “[u]nder the plain language of the
    statute[,]” damages must be established). Damages is an inherent element
    of larceny.
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 15
    amount by which [the defendant] has been enriched” (quoting
    Rest., Restitution, § 1, com. e)); see also Ghirardo v.
    Antonioli, 
    14 Cal. 4th 39
    , 51 (1996) (“Under the law of
    restitution, an individual may be required to make restitution
    if he is unjustly enriched at the expense of another.”).
    In other words, California law requires disgorgement of
    unjustly earned profits regardless of whether a defendant’s
    actions caused a plaintiff to directly expend his or her own
    financial resources or whether a defendant’s actions directly
    caused the plaintiff’s property to become less valuable. See,
    e.g., CTC Real Estate Servs. v. Lepe, 
    140 Cal. App. 4th 856
    ,
    860–61 (2006) (holding that a woman whose identity was
    stolen and used to obtain later-foreclosed-upon property was
    entitled to surplus funds from the sale at auction because “she
    was entitled to the product of identity theft”); Ward v.
    Taggert, 
    51 Cal. 2d 736
    , 742–43 (1959) (holding that
    plaintiffs could recover profits unjustly realized by a real
    estate agent who misrepresented the purchase price of real
    estate, even though the plaintiffs did not pay more than the
    land was worth when they purchased it); cf. Walsh, 158 Cal.
    App. 4th at 542–43 (holding that the district court did not err
    where it solely relied on profit to the defendants rather than
    loss to the plaintiffs to calculate damages).
    “The ‘gist of the question of standing’ is whether the
    plaintiff has a sufficiently ‘personal stake in the outcome of
    the controversy.’” Washington v. Trump, 
    847 F.3d 1151
    ,
    1159 (9th Cir. 2017) (quoting Massachusetts v. EPA,
    
    549 U.S. 497
    , 517 (2007)). Because California law
    recognizes that individuals maintain an entitlement to
    unjustly earned profits, to establish standing, Plaintiffs must
    allege they retain a stake in the profits garnered from their
    personal browsing histories because “the circumstances are
    16 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    such that, as between the two [parties], it is unjust for
    [Facebook] to retain it.” McBride v. Boughton, 
    123 Cal. App. 4th 379
    , 389 (2004) (emphasis in original) (quoting First
    Nationwide Savings v. Perry, 
    11 Cal. App. 4th 1657
    , 1662
    (1992)). Under California law, this stake in unjustly earned
    profits exists regardless of whether an individual planned to
    sell his or her data or whether the individual’s data is made
    less valuable.
    Because California law recognizes a legal interest in
    unjustly earned profits, Plaintiffs have adequately pleaded an
    entitlement to Facebook’s profits from users’ personal data
    sufficient to confer Article III standing. Plaintiffs allege that
    their browsing histories carry financial value. They point to
    the existence of a study that values users’ browsing histories
    at $52 per year, as well as research panels that pay
    participants for access to their browsing histories.
    Plaintiffs also sufficiently allege that Facebook profited
    from this valuable data. According to the complaint,
    Facebook sold user data to advertisers in order to generate
    revenue. Indeed, as alleged, Facebook’s ad sales constituted
    over 90% of the social media platform’s revenue during the
    relevant period of logged-out user tracking.
    Plaintiffs’ allegations are sufficient at the pleading stage
    to demonstrate that these profits were unjustly earned. As
    stated in the complaint, “despite Facebook’s false guarantee
    to the contrary,” the platform “charges users by acquiring the
    users’ sensitive and valuable personal information” and
    selling it to advertisers for a profit. Plaintiffs allegedly did
    not provide authorization for the use of their personal
    information, nor did they have any control over its use to
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 17
    produce revenue. This unauthorized use of their information
    for profit would entitle Plaintiffs to profits unjustly earned.
    Thus, Plaintiffs sufficiently alleged a state law interest
    whose violation constitutes an injury sufficient to establish
    standing to bring their claims for CDAFA violations and
    California common law trespass to chattels, fraud, and
    statutory larceny.
    III
    Plaintiffs adequately stated claims for relief for invasion
    of privacy, intrusion upon seclusion, breach of contract,
    breach of the implied covenant of good faith and fair dealing,
    as well as their claims under the Wiretap Act and CIPA. In
    order to survive a motion to dismiss under Federal Rule of
    Civil Procedure 12(b)(6), the facts alleged must “plausibly
    give rise to an entitlement to relief.” Dougherty, 
    654 F.3d at 897
     (quoting Ashcroft v. Iqbal, 
    556 U.S. 662
    , 679 (2009)).
    At the pleading stage, all allegations of material fact are taken
    as true and construed in the light most favorable to the non-
    moving party. 
    Id.
    A
    Plaintiffs adequately stated claims for relief for intrusion
    upon seclusion and invasion of privacy under California law.
    To state a claim for intrusion upon seclusion under California
    common law, a plaintiff must plead that (1) a defendant
    “intentionally intrude[d] into a place, conversation, or matter
    as to which the plaintiff has a reasonable expectation of
    privacy[,]” and (2) the intrusion “occur[red] in a manner
    highly offensive to a reasonable person.” Hernandez v.
    Hillsides, Inc., 
    47 Cal. 4th 272
    , 286 (2009).
    18 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    A claim for invasion of privacy under the California
    Constitution involves similar elements. Plaintiffs must show
    that (1) they possess a legally protected privacy interest,
    (2) they maintain a reasonable expectation of privacy, and (3)
    the intrusion is “so serious . . . as to constitute an egregious
    breach of the social norms” such that the breach is “highly
    offensive.” 
    Id. at 287
    .
    Because of the similarity of the tests, courts consider the
    claims together and ask whether: (1) there exists a reasonable
    expectation of privacy, and (2) the intrusion was highly
    offensive. 
    Id.
     We address both in turn.
    1
    The existence of a reasonable expectation of privacy,
    given the circumstances of each case, is a mixed question of
    law and fact. Hill v. NCAA, 
    7 Cal. 4th 1
    , 40 (1994).
    “[M]ixed questions of fact and law are reviewed de novo,
    unless the mixed question is primarily factual.” N.B. v.
    Hellgate Elem. Sch. Dist., ex rel. Bd. of Dirs., Missoula Cty.,
    Mont., 
    541 F.3d 1202
    , 1207 (9th Cir. 2008). Here, because
    we are reviewing the district court’s legal conclusions, we
    review de novo.
    We first consider whether a defendant gained “unwanted
    access to data by electronic or other covert means, in
    violation of the law or social norms.” Hernandez, 
    47 Cal. 4th at 286
     (internal quotation marks omitted). To make this
    determination, courts consider a variety of factors, including
    the customs, practices, and circumstances surrounding a
    defendant’s particular activities. Hill, 
    7 Cal. 4th at 36
    .
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 19
    Thus, the relevant question here is whether a user would
    reasonably expect that Facebook would have access to the
    user’s individual data after the user logged out of the
    application. Facebook’s privacy disclosures at the time
    allegedly failed to acknowledge its tracking of logged-out
    users, suggesting that users’ information would not be
    tracked.
    The applicable Facebook Statement of Rights and
    Responsibilities (“SRR”) stated:
    Your privacy is very important to us. We
    designed our Privacy Policy to make
    important disclosures about how you can use
    Facebook to share with others and how we
    collect and can use your content and
    information. We encourage you to read the
    Privacy Policy, and to use it to make informed
    decisions.
    SRR, dated April 26, 2011.
    Facebook’s applicable Data Use Policy,5 in turn, stated:
    We receive data whenever you visit a game,
    application, or website that uses [Facebook’s
    services]. This may include the date and time
    you visit the site; the web address, or URL,
    you’re on; technical information about the IP
    address, browser and the operating system
    5
    This policy was originally titled “Privacy Policy.” During the class
    period, its title was changed to “Data Use Policy.”
    20 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    you use; and, if you are logged in to
    Facebook, your user 
    ID.
    Data Use Policy, dated September 7, 2011 (emphasis added).
    Finally, Facebook’s “Help Center” at the time included
    answers to questions related to data tracking. Most
    relevantly, one answer from a Help Center page at the time
    answered the question “[w]hat information does Facebook
    receive about me when I visit a website with a Facebook
    social plug in?”6 The Help Center page first stated that
    Facebook collected the date and time of the visit, the referer
    URL, and other technical information. It continued, “[i]f you
    are logged into Facebook, we also see your user ID number
    and email address. . . . If you log out of Facebook, we will
    not receive this information about partner websites but you
    will also not see personalized experiences on these sites.”
    Plaintiffs have plausibly alleged that an individual reading
    Facebook’s promise to “make important privacy disclosures”
    could have reasonably concluded that the basics of
    Facebook’s tracking—when, why, and how it tracks user
    information—would be provided. Plaintiffs have plausibly
    alleged that, upon reading Facebook’s statements in the
    applicable Data Use Policy, a user might assume that only
    logged-in user data would be collected. Plaintiffs have
    alleged that the applicable Help Center page affirmatively
    stated that logged-out user data would not be collected. Thus,
    Plaintiffs have plausibly alleged that Facebook set an
    6
    Facebook disputes that some of the Help Center pages Plaintiffs
    attached to their complaint were dated during the class period. It does not
    dispute, however, that this particular Help Center page fell within the class
    period.
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 21
    expectation that logged-out user data would not be collected,
    but then collected it anyway.
    In addition, the amount of data allegedly collected was
    significant. Plaintiffs allege that “[n]o matter how sensitive
    the website, the referral URL is acquired by Facebook along
    with the cookies that precisely identify the [logged-out] user”
    and that Facebook acquires an “enormous amount of
    individualized data” through its use of cookies on the
    countless websites that incorporate Facebook plug-ins. That
    this amount of information can be easily collected without
    user knowledge is similarly significant. Plaintiffs have
    plausibly alleged that Facebook did not disclose that the
    cookies would continue to track users’ browsing history after
    they log out of the platform. Nor did it disclose the extent of
    information collected.
    In light of the privacy interests and Facebook’s allegedly
    surreptitious and unseen data collection, Plaintiffs have
    adequately alleged a reasonable expectation of privacy. Case
    law supports this determination.           In In re Google
    Cookie—where the Third Circuit similarly interpreted
    California Law—the court held that users maintained a
    reasonable expectation of privacy in their browsing histories
    when Google tracked URLs after the users denied consent for
    such tracking. 806 F.3d at 129, 151; see also In re
    Nickelodeon Cons. Priv. Litig., 
    827 F.3d 262
    , 293–94 (3d Cir.
    2016) (“In re Nickelodeon”) (holding, under analogous New
    Jersey law, that a reasonable expectation of privacy existed
    when Nickelodeon promised users that it would not collect
    information from website users, but then did). That users in
    those cases explicitly denied consent does not render those
    cases distinguishable from the instant case, given Facebook’s
    affirmative statements that it would not receive information
    22 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    from third-party websites after users had logged out. Indeed,
    in those cases, the critical fact was that the online entity
    represented to the plaintiffs that their information would not
    be collected, but then proceeded to collect it anyway.
    The nature of the allegedly collected data is also
    important. Plaintiffs allege that Facebook obtained a
    comprehensive browsing history of an individual, no matter
    how sensitive the websites visited, and then correlated that
    history with the time of day and other user actions on the
    websites visited. This process, according to Plaintiffs,
    resulted in Facebook’s acquiring “an enormous amount of
    individualized data” to compile a “vast repository of personal
    data.”
    Facebook argues that Plaintiffs need to identify specific,
    sensitive information that Facebook collected, and that their
    more general allegation that Facebook acquired “an enormous
    amount of individualized data” is insufficient. However, both
    the nature of collection and the sensitivity of the collected
    information are important. The question is not necessarily
    whether Plaintiffs maintained a reasonable expectation of
    privacy in the information in and of itself. Rather, we must
    examine whether the data itself is sensitive and whether the
    manner it was collected—after users had logged
    out—violates social norms.
    When we consider the sensitivity of that data, moreover,
    we conclude there remain material questions of fact as to
    whether a reasonable individual would find the information
    collected from the seven million websites that employ
    Facebook plug-ins “sensitive and confidential.” Hill, 
    7 Cal. 4th at 35
    . “Technological advances[,]” such as Facebook’s
    use of cookies to track and compile internet browsing
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 23
    histories, “provide ‘access to a category of information
    otherwise unknowable’ and ‘implicate privacy concerns’ in
    a manner different from traditional intrusions as a ‘ride on
    horseback’ is different from ‘a flight to the moon.’” Patel,
    932 F.3d at 1273 (quoting Riley v. California, 
    573 U.S. 373
    ,
    393 (2014)). Thus, viewing the allegations in the light most
    favorable to Plaintiffs, as we must at this stage, the
    allegations that Facebook allegedly compiled highly
    personalized profiles from sensitive browsing histories and
    habits prevent us from concluding that the Plaintiffs have no
    reasonable expectation of privacy.7
    7
    Analogous cases decided in the Fourth Amendment context support
    a conclusion that the breadth of information allegedly collected would
    violate community norms. These cases hold that individuals have a
    reasonable expectation of privacy in collections of information that reveal
    “familiar, political, professional, religious, and sexual associations.” See
    Carpenter v. United States, 
    138 S. Ct. 2206
    , 2217 (2018) (holding that
    individuals have a reasonable expectation of privacy in long-term location
    tracking data under the Fourth Amendment because it reveals all-
    encompassing information); Riley, 573 U.S. at 397–99 (holding that
    individuals have a reasonable expectation of privacy in the contents of
    their cell phones under the Fourth Amendment due to the large amount of
    personal data stored therein); United States v. Forrester, 
    512 F.3d 500
    ,
    510 n.6 (9th Cir. 2008) (noting that, in a Fourth Amendment search
    context, URLs may be particularly sensitive because they “identif[y] the
    particular document within a website that a person views and thus reveals
    much more information about the person’s Internet activity”). We
    acknowledge that the Fourth Amendment imposes higher standards on the
    government than those on private, civil litigants. Carpenter, 
    138 S. Ct. at
    2213–14. But we have nonetheless found analogies to Fourth
    Amendment cases applicable when deciding issues of privacy related to
    technology. See Patel, 932 F.3d at 1272–73. And, viewed broadly, these
    cases stand for the proposition that individuals maintain the expectation
    that entities will not be able to collect such broad swaths of personal
    information absent consent.
    24 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    Contrary to Facebook’s arguments, this case can also be
    distinguished from Forrester and Zynga as it relates to an
    analysis of a reasonable expectation of privacy. Forrester,
    
    512 F.3d 500
    ; Zynga, 
    750 F.3d 1098
    . In Forrester, we
    considered whether the individuals had a reasonable
    expectation of privacy in “the to/from addresses of their
    messages or the IP addresses of the websites they visit.”
    
    512 F.3d at 510
    . Concluding that users did not maintain a
    reasonable expectation of privacy in such information, we
    determined that users “should know that this information is
    provided to and used by Internet service providers for the
    specific purposes of directing the routing information.” 
    Id.
    But, in a footnote, we went on to distinguish the IP addresses
    collected in Forrester from the collection of URLs, which we
    stated “might be more constitutionally problematic,”
    explaining that, “[a] URL, unlike an IP address, identifies the
    particular document within a website that a person views and
    thus reveals much more information about the person’s
    Internet activity.” Id. at n.6.
    In Zynga, the plaintiffs relied on this footnote to argue
    that they maintained a reasonable expectation of privacy in
    the URLs of gaming websites collected without their
    knowledge and disclosed to third parties by Zynga (a gaming
    platform) and Facebook. 750 F.3d at 1108–09. The Zynga
    plaintiffs alleged that users would log in to their Facebook
    account and “then click on the Zynga game icon within the
    Facebook interface.” Id. at 1102. Facebook and Zynga
    would then collect a referer header containing the URL for
    the Zynga game, after which the Zynga server would load the
    game in a small frame embedded on the Facebook website.
    Id. According to the Zynga plaintiffs, “Zynga programmed
    its gaming applications to collect the information provided in
    the referer header, and then transmit this information to
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 25
    advertisers and other third parties.” Id. This information
    included “the user’s Facebook ID and the address of the
    Facebook webpage the user was viewing when the user
    clicked the link.” Id. at 1102.
    In Zynga, we concluded that the collected information
    was not problematic because it differed from the URLs
    containing sensitive information alluded to in Forrester’s
    footnote. We determined that “[i]nformation about the
    address of the Facebook webpage the user was viewing is
    distinguishable from the sort of communication involving a
    search engine discussed in Forrester.” Id. at 1108. We then
    continued to say that “a Google search URL not only shows
    that a user is using the Google search engine, but also shows
    the specific search terms the user had communicated to
    Google.” Id. We continued, “the referer header information
    at issue here includes only basic identification and address
    information, not a search term or similar communication
    made by the user.” Id. at 1108–09.
    Here, Plaintiffs allege that Facebook collects a full-string
    detailed URL, which contains the name of a website, folder
    and sub-folders on the web-server, and the name of the
    precise file requested. Their complaint notes that a user
    might type a search term into Google’s search engine, which
    would return a link to an article relevant to the search term.
    According to Plaintiffs, when the user clicks the link, a
    communication is created that contains a “GET request and
    the full-string detailed URL.” They allege that Facebook
    collected this communication, including the “full referral
    URL (including the exact subpage of the precise items being
    purchased)” and that Facebook then “correlates that URL
    with the user ID, time stamp, browser settings and even the
    type of browser used.”
    26 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    In sum, Plaintiffs allege that a Google search could
    generate links that include full-string, detailed URLs that
    Facebook then collected. Thus, they have sufficiently alleged
    that the collected URLs in this case are distinct from IP
    addresses collected in Forrester, as well as the URLs
    collected in Zynga. The URLs, by virtue of including “the
    particular document within a website that a person views”
    reveal “much more information” than the IP addresses
    collected in Forrester. 
    512 F.3d at
    510 n.6. Unlike the URLs
    in Zynga, which revealed only that a Facebook user had
    clicked on a link to a gaming website, Plaintiffs allege that
    the URLs in the instant case could emanate from search terms
    inputted into a third-party search engine. These terms and the
    resulting URLs could divulge a user’s personal interests,
    queries, and habits on third-party websites operating outside
    of Facebook’s platform.
    Moreover, the users in Zynga clicked on links to the
    gaming websites after they had logged into their Facebook
    user accounts. Zynga, 750 F.3d at 1102. Then, the linked
    material appeared within the Facebook interface. Id. Here,
    in contrast, Plaintiffs allege that users were not logged in to
    the website, making it impossible for the linked material to be
    viewed within Facebook’s interface.
    The fact that users could have taken additional measures
    to prevent cookies from tracking their browsing, as Facebook
    asserts, is not relevant at the pleading stage. This is a fact-
    based defense to be developed and asserted at a later stage of
    the litigation. And Plaintiffs have alleged that these
    protections would not have done any good, even if users had
    employed them. Specifically, they allege that Facebook
    would “hack its way past data protection software” to
    “bypass[] security settings for the purpose of gathering
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 27
    intelligence” on the users’ real-time searches, and similarly,
    with respect to a subclass of individuals who used the Internet
    Explorer browser, that Facebook fraudulently maintained that
    it employed a protocol that would result in its tracking being
    automatically blocked by the browser. These issues cannot
    be resolved at the pleading stage.
    In sum, Plaintiffs have sufficiently pleaded a reasonable
    expectation of privacy to survive a Rule 12(b)(6) motion to
    dismiss.
    2
    However, in order to maintain a California common law
    privacy action, “[p]laintiffs must show more than an
    intrusion upon reasonable privacy expectations. Actionable
    invasions of privacy also must be ‘highly offensive’ to a
    reasonable person, and ‘sufficiently serious’ and unwarranted
    so as to constitute an ‘egregious breach of the social norms.’”
    Hernandez, 
    47 Cal. 4th at 295
    . Determining whether a
    defendant’s actions were “highly offensive to a reasonable
    person” requires a holistic consideration of factors such as the
    likelihood of serious harm to the victim, the degree and
    setting of the intrusion, the intruder’s motives and objectives,
    and whether countervailing interests or social norms render
    the intrusion inoffensive. 
    Id. at 287
    ; see also Hill, 
    7 Cal. 4th at
    25–26. While analysis of a reasonable expectation of
    privacy primarily focuses on the nature of the intrusion, the
    highly offensive analysis focuses on the degree to which the
    intrusion is unacceptable as a matter of public policy.
    Hernandez, 
    47 Cal. 4th at 287
     (noting that highly offensive
    analysis “essentially involves a ‘policy’ determination as to
    whether the alleged intrusion is highly offensive under the
    particular circumstances”).
    28 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    The ultimate question of whether Facebook’s tracking and
    collection practices could highly offend a reasonable
    individual is an issue that cannot be resolved at the pleading
    stage. Plaintiffs have identified sufficient facts to survive a
    motion to dismiss. Plaintiffs’ allegations of surreptitious data
    collection when individuals were not using Facebook are
    sufficient to survive a dismissal motion on the issue. Indeed,
    Plaintiffs have alleged that internal Facebook
    communications reveal that the company’s own officials
    recognized these practices as a problematic privacy issue.
    In sum, Plaintiffs have sufficiently pleaded the
    “reasonable expectation of privacy” and “highly offensive”
    elements necessary to state a claim for intrusion upon
    seclusion and invasion of privacy to survive a 12(b)(6)
    motion to dismiss.8
    B
    Plaintiffs also have sufficiently alleged that Facebook’s
    tracking and collection practices violated the Wiretap Act and
    CIPA.
    8
    The non-precedential cases cited by Facebook do not compel the
    opposite conclusion. For instance, in In re Google, Inc. Privacy Policy
    Litig., the Northern District of California found no highly offensive
    conduct when Plaintiffs alleged that Google surreptitiously tracked their
    browsing data while using Google’s services. 
    58 F. Supp. 3d 968
    , 987–88
    (N.D. Cal. 2014). Here, on the other hand, Plaintiffs had logged out and
    were not using Facebook when Facebook tracked them. The same is true
    in Low v. LinkedIn Corp., 
    900 F. Supp. 2d 1010
    , 1016–18 (N.D. Cal.
    2012) and In re iPhone App. Litig., 
    844 F. Supp. 2d 1040
    , 1049–50 (N.D.
    Cal. 2012). In those cases, there were likewise no allegations that the
    defendants tracked the plaintiffs after the plaintiffs stopped using the
    defendant’s services.

    The Wiretap Act prohibits the unauthorized “interception”
    of an “electronic communication.”                 
    18 U.S.C. § 2511
    (1)(a)–(e). Similarly, CIPA prohibits any person from
    using electronic means to “learn the contents or meaning” of
    any “communication” “without consent” or in an
    “unauthorized manner.” 
    Cal. Pen. Code § 631
    (a). Both
    statutes contain an exemption from liability for a person who
    is a “party” to the communication, whether acting under the
    color of law or not. 
    18 U.S.C. § 2511
    (2)(c), (d); see Warden
    v. Kahn, 
    160 Cal. Rptr. 471
    , 475 (1979) (“[S]ection 631 . . .
    has been held to apply only to eavesdropping by a third party
    and not to recording by a participant to a conversation.”).
    Courts perform the same analysis for both the Wiretap Act
    and CIPA regarding the party exemption. See, e.g., In re
    Google Cookie, 806 F.3d at 152 (holding that CIPA claims
    could be dismissed because the parties were exempted from
    liability under the Wiretap Act’s party exception).
    The party exception must be considered in the technical
    context of this case. When an individual internet user visits a
    web page, his or her browser sends a message called a “GET
    request” to the web page’s server. The GET request serves
    two purposes: it first tells the website what information is
    being requested and then instructs the website to send the
    information back to the user. The GET request also transmits
    a referer header containing the personally-identifiable URL
    information. Typically, this communication occurs only
    between the user’s web browser and the third-party website.
    On websites with Facebook plug-ins, however, Facebook’s
    code directs the user’s browser to copy the referer header
    from the GET request and then send a separate but identical
    GET request and its associated referer header to Facebook’s
    30 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    server. It is through this duplication and collection of GET
    requests that Facebook compiles users’ browsing histories.
    The Wiretap Act does not define the term “party” in its
    liability exemption, and the other circuit courts that have
    considered the Act’s scope have interpreted the term in
    different ways. The First and Seventh Circuits have
    implicitly assumed that entities that surreptitiously duplicate
    transmissions between two parties are not parties to
    communications within the meaning of the Act. In In re
    Pharmatrak, Inc. Privacy Litig., the First Circuit considered
    whether the defendant could face liability under the Wiretap
    Act when it employed software that “automatically duplicated
    part of the communication between a user and a [third-party
    website] and sent this information to [the defendant].” 
    329 F.3d 9
    , 22 (1st Cir. 2003). The First Circuit rejected the
    defendant’s argument that “there was no interception because
    ‘there were always two separate communications: one
    between the Web user and the [third-party website], and the
    other between the Web user and [the defendant].’” 
    Id.
    Noting that the defendant “acquired the same URL . . .
    exchanged as a part of the communication between the [third-
    party website] and the user,” it determined that the
    defendant’s acquisition constituted an interception and could
    still render it liable. 
    Id.
    In United States v. Szymuszkiewicz, the Seventh Circuit
    reached a similar conclusion. 
    622 F.3d 701
     (7th Cir. 2010).
    In that case, the Seventh Circuit considered whether a
    defendant violated the Wiretap Act when he employed a
    software that instructed his employer’s email to duplicate and
    forward all emails the employer received to the defendant’s
    own inbox. 
    Id. at 703
    . The court determined that, because
    the copies were sent contemporaneously with the original
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 31
    emails, the defendant had intercepted the communications
    and could be held liable. 
    Id. at 706
    .
    However, the Third Circuit has held to the contrary. In In
    re Google Cookie, the court considered whether internet
    advertising companies were parties to a communication when
    they placed cookie blockers on web-users’ browsers to
    facilitate online advertisements. 806 F.3d at 143. As in the
    instant case, the users sent GET requests to third-party
    websites and upon receipt, the website would duplicate the
    GET request and send it to the defendants. Id. at 140. The
    Third Circuit concluded that the defendants were “the
    intended recipients” of the duplicated GET requests, and thus
    “were parties to the transmissions at issue.” Id. at 143; see
    also In re Nickelodeon, 827 F.3d at 275–76 (citing In re
    Google Cookie for the same).9
    We adopt the First and Seventh Circuits’ understanding
    that simultaneous, unknown duplication and communication
    of GET requests do not exempt a defendant from liability
    under the party exception. As we have previously held, the
    “paramount objective of the [Electronic Communications
    Privacy Act, which amended the Wiretap Act] is to protect
    effectively the privacy of communications.” Joffe v. Google,
    
    746 F.3d 920
    , 931 (9th Cir. 2013). We also recognize that the
    Wiretap Act’s legislative history evidences Congress’s intent
    to prevent the acquisition of the contents of a message by an
    9
    In Konop v. Hawaiian Airlines, Inc., we adopted a definition of
    “intercept” that encompassed both an “acquisition contemporaneous with
    transmission” and an act requiring a party to “stop, seize, or interrupt in
    progress or course before arrival.” 
    302 F.3d 868
    , 878 (9th Cir. 2002). In
    that case, however, we considered whether items viewed on a private
    website were intercepted, in violation of the Wiretap Act, not plug-ins that
    duplicated and sent GET requests, as we consider here.
    32 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    unauthorized third-party or “an unseen auditor.” See S. REP.
    NO. 90-1097, reprinted in 1986 U.S.C.C.A.N. 2112, 2154,
    2182. Permitting an entity to engage in the unauthorized
    duplication and forwarding of unknowing users’ information
    would render permissible the most common methods of
    intrusion, allowing the exception to swallow the rule.
    Therefore, we conclude that Facebook is not exempt from
    liability as a matter of law under the Wiretap Act or CIPA as
    a party to the communication. We do not opine whether the
    Plaintiffs adequately pleaded the other requisite elements of
    the statutes, as those issues are not presented on appeal.
    C
    The district court properly dismissed Plaintiffs’ SCA
    claims. The SCA requires Plaintiffs to plead that Facebook
    (1) gained unauthorized access to a “facility” where it
    (2) accessed an electronic communication in “electronic
    storage.” 
    18 U.S.C. § 2701
    (a).
    Electronic storage is defined as either the “temporary,
    intermediate storage of a wire or electronic communication
    incidental to the electronic transmission thereof” and “any
    storage of such communication by an electronic
    communication service for purposes of backup protection of
    such communication.” 
    18 U.S.C. § 2510
    (17).
    Plaintiffs allege that “[w]eb-browsers store a copy of the
    Plaintiffs’ URL requests in the toolbar while the user remains
    present at a particular webpage,” and that this storage is
    incidental to the electronic communication because once “the
    user hits the Enter button or clicks on a link, the
    communication is in the process of being sent and received
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 33
    between the user and the first-party website.” Plaintiffs
    similarly assert that their browsing history—a record of
    previously viewed websites—serves purposes of “backup
    protection” of such communications. In short, Plaintiffs
    allege that the URL is in “electronic storage” in the toolbar
    during the split-second that it takes to complete a search. In
    Plaintiffs’ view, because Facebook duplicates the URL and
    sends it to its servers during that split second, it accesses the
    URL while it is in this “electronic storage.”
    The district court considered the GET requests that
    Facebook duplicated and forwarded to its servers as wholly
    separate from the copy of the URL displayed in the search
    toolbar. Because the copy in the toolbar was not stored
    “incident to transmission” but was only present for the user’s
    convenience, the district court determined that the Plaintiffs’
    data was not in electronic storage.
    We agree. The communications in question—the GET
    requests themselves—are not the communications stored in
    the user’s toolbar. Rather, the GET requests are sent directly
    between the user and the third-party website. The text
    displayed in the toolbar serves only as a visual indication—a
    means of informing the user—of the location of their
    browser. Thus, the URL’s appearance in the toolbar is not
    “incidental” to the transmission of the URL or GET request.
    What is more, Plaintiffs’ interpretation of the SCA would
    stretch its application beyond its limits. True, the SCA’s
    legislative history suggests that Congress intended the term
    “electronic storage” to be broadly construed, and not limited
    to “particular mediums, forms, or locations.” Hately v. Watts,
    
    917 F.3d 770
    , 786 (4th Cir. 2019) (citing H.R. REP., NO. 99-
    647, at 39 (1986)). Nonetheless, the text and legislative
    34 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    history of the SCA demonstrate that its 1986 enactment was
    driven by congressional desire to protect third-party entities
    that stored information on behalf of users. See 
    id. at 782
    (noting that the SCA was enacted to protect against illicit
    access to stored communications in “remote computing
    operations and large data banks that stored emails”). Since
    then, the SCA has typically only been found to apply in cases
    involving a centralized data-management entity; for instance,
    to protect servers that stored emails for significant periods of
    time between their being sent and their recipients’ reading
    them. See 
    id. at 798
     (considering whether a web-based email
    service “stored” emails); Theofel v. Farey-Jones, 
    359 F.3d 1066
    , 1072 (9th Cir. 2004) (considering whether emails
    stored by an internet service provider fell under the statute’s
    purview). Here, the allegations, even construed in the light
    most favorable to Plaintiffs, do not show that the
    communications were even in “storage,” much less that the
    alleged “storage” within a URL toolbar falls within the
    SCA’s intended scope.
    Plaintiffs alternatively argue that their browsing histories
    are stored for “purposes of back-up” and thus satisfy the
    SCA’s electronic storage definition. Plaintiffs note that, in
    Theofel, we held that a copy of information stored on a user’s
    computer “in the event that the user needs to download it
    again” constituted storage for backup purposes. 
    359 F.3d at 1075
    . In this case, however, the browsing histories are not
    composed of the actual communications sent between the
    individuals—rather, the browsing histories are merely a
    record of URLs visited. Thus, Plaintiffs’ claims for relief
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 35
    under the SCA are insufficient, and the district court correctly
    dismissed them.10
    D
    The district court also properly held that the Plaintiffs
    have not stated a breach of contract claim. In order to
    establish a contract breach, Plaintiffs must allege: (1) the
    existence of a contract with Facebook, (2) their performance
    under that contract, (3) Facebook breached that contract, and
    (4) they suffered damages. Oasis West Realty, LLC v.
    Goldman, 
    51 Cal. 4th 811
    , 821 (2011).
    Plaintiffs allege that Facebook entered into a contract with
    each Plaintiff consisting of the SRR, Privacy Policy, and
    relevant Help Center pages. The parties agree that the SRR
    constitutes a contract. In their third amended complaint,
    Plaintiffs attached the SRR that was last revised April 26,
    2011. This document states “[y]our privacy is very important
    to us” and “[w]e encourage you to read the Privacy Policy,
    and to use it to help make informed decisions.” But this
    document does not contain an explicit promise not to track
    logged-out users. For that allegation, Plaintiffs instead rely
    on language from the Data Use Policy and the Help Center
    pages.
    To properly incorporate another document, the document
    “need not recite that it incorporates another document, so
    long as it guide[s] the reader to the incorporated document.”
    10
    Because we hold that the URLs are not in electronic storage, we
    need not decide whether Plaintiffs sufficiently allege that their personal
    computers, web browsers, and browser managed files are “facilities,”
    through which electronic communications service providers operate.
    36 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    Shaw v. Regents of the Univ. of Cal., 
    58 Cal. App. 4th 44
    , 54
    (1997) (internal quotations and citations omitted). During the
    class period, Facebook changed the title of its “Privacy
    Policy” to “Data Use Policy” and made adjustments to its
    content. Although the relevant SRR directs readers to the
    Privacy Policy, Plaintiffs rely on the latest version of this
    document, titled “Data Use Policy,” last revised September 7,
    2011. The attached SRR does not reference a Data Use
    Policy and thus, it does not guide the reader to the
    incorporated document on which Plaintiffs rely. As such, as
    a matter of law, any promise not to track logged-out users
    therein was not incorporated.
    On appeal, Plaintiffs argue that the Data Use Policy
    constitutes an additional agreement separate from the SRR.
    Plaintiffs support this allegation with text from the September
    2011 Data Use Policy, which states that, were Facebook to
    transfer ownership, the new owner would “still have to honor
    the commitments we have made in this privacy policy,” and
    the December 2010 Privacy Policy, which states “[b]y using
    or accessing Facebook, you agree to our privacy practices
    outlined here.”
    First, the December 2010 Privacy Policy does not contain
    any agreement that Facebook would not track logged-out user
    data.11 Second, and more generally, the Privacy and Data Use
    Policies do not outline shared commitments to which users
    must abide. For a contract to exist, there must be an
    11
    The December 2010 Privacy Policy states: “If you log out of
    Facebook before visiting a pre-approved application or website, it will not
    be able to access your information.” This statement merely provides that
    the third-party websites will not receive a user’s information. It does not
    make any promises regarding Facebook’s receipt of data.
    IN RE FACEBOOK, INC. INTERNET TRACKING LITIG. 37
    exchange for a promise. Steiner v. Thexton, 
    48 Cal. 4th 411
    ,
    421 (2010). The 2011 Data Use Policy does not contain any
    exchange. To illustrate, while the SRR outlines commitments
    to which both Facebook and users agree (for example, users
    agree not to “send or otherwise post unauthorized commercial
    communications” on Facebook, while Facebook promises to
    “provide . . . tools to help you protect your property rights”),
    the 2011 Data Use Policy merely provides information—not
    commitments—regarding Facebook’s use of information and
    how users can control that information (for example, it states
    that “[y]our information is the information that’s required
    when you sign up for the site”). Plaintiffs’ reliance on one
    use of the term “commitment” within this document cannot
    overcome the fact that the document does not require the user
    to make any commitment. Thus, the Data Use Policy does
    not constitute a separate contract. Because Plaintiffs have
    failed to allege adequately the existence of a contract that was
    subject to breach, we affirm the district court’s dismissal of
    their breach of contract claim.
    Plaintiffs also alleged that Facebook’s tracking practices
    violated the implied covenant of good faith and fair dealing.
    However, as pleaded, the allegations did not go beyond the
    breach of contract theories asserted by Plaintiffs and were
    thus properly dismissed. Carau & Co. v. Sec. Pac. Bus.
    Credit, Inc., 
    222 Cal. App.3d 1371
    , 1395 (1990).
    IV
    In sum, we conclude that Plaintiffs have standing to assert
    their claims. We affirm the district court’s dismissal of the
    SCA, breach of contract, and breach of implied covenant
    claims. We conclude that Plaintiffs adequately pleaded their
    remaining claims at this early stage to survive a motion to
    38 IN RE FACEBOOK, INC. INTERNET TRACKING LITIG.
    dismiss under Rule 12(b)(6). We remand these issues to the
    district court for further consideration. We do not reach any
    other issue argued by the parties, leaving those issues for
    consideration by the district court in the first instance. All
    pending motions are denied as moot. The parties shall bear
    their own costs.
    AFFIRMED IN PART, REVERSED IN PART, AND
    REMANDED.
