Opinion

DANIEL GLIKSMAN, Case No.24-cv-08650-AMO Plaintiff, ORDER GRANTING IN PART AND v. DENYING IN PART MOTION TO DISMISS Re: Dkt. No. 51 Defendant.

This is a putative data privacy class action. Defendant Healthline Media, LLC’s motion to dismiss was heard before this Court on February 5, 2026. Having read the parties’ papers and carefully considered the arguments therein and those made at the hearing, as well as the relevant legal authority, and good cause appearing, the Court GRANTS IN PART and DENIES IN PART the motion for the following reasons. A. Factual Background1 Healthline Media, LLC (“Healthline”) operates a portfolio of consumer-facing websites which publish health and wellness-related articles. Dkt. No. 44, Amended Complaint ¶¶ 1, 17, 20 (“Am. Compl.”). Healthline’s websites use third-party trackers known as “pixels.” Id. ¶ 3. Specifically, Healthline uses the TikTok Pixel, the Microsoft Clarity Pixel, and the Adnx Pixel (collectively, the “Pixels”). Id. ¶ 6. The Pixels track, record, and collect website users’ information, including their searches and IP addresses, which are subsequently communicated to 1 These facts are drawn from the allegations in Gliksman’s complaint, which the Court accepts as true and construes in the light most favorable to Gliksman. See Manzarek v. St. Paul Fire & third party platforms and advertisers – TikTok and Microsoft – without consent from the website’s visitor. Id. ¶¶ 4-5, 21. Healthline leverages the user data to sell advertising space on its websites and to earn additional revenue. Id. ¶ 7. The Pixels also allow Healthline to place advertisements on other companies’ websites, increasing brand awareness and sales. Id. The data that the Pixels collect from consumers can be used to identify specific individuals, even without information such as the person’s name or address, and to determine the location of the individual. Id. ¶ 8. TikTok Pixel. The TikTok Pixel enables advertisers to track users’ website interactions through the user’s browser. Id. ¶ 33. “The TikTok Pixel collects and transmits search terms, URL[s], or article titles that convey health symptoms, conditions, or diagnoses in addition to supplementary metadata, including information such as ad/event details (related to the clicked ad), timestamp (time page was viewed), IP address (which can identify a person’s geographic location), device details (make, model, operating system) and browser information.” Id. ¶ 34. The TikTok Pixel uses a process called “fingerprinting,” through which the Pixel collects as much data as it can about an anonymous website visitor and matches it with existing data that TikTok has acquired about millions of users. Id. ¶ 36. The TikTok Pixel also offers an “AutoAdvanced Matching” feature which automatically collects additional information from visitors who interact with a business’s website or application, such as email addresses, phone numbers, and other identifiers. Id. ¶ 38. Microsoft Clarity Pixel. Healthline also implements the Microsoft Clarity Pixel and, in addition to other information, discloses users’ Machine Unique Identifier (“MUID”) to Microsoft, which is a unique and persistent identifier generated by Microsoft and assigned to a specific browser to track users’ activity across the internet. Id. ¶¶ 43-44. Adnx Pixel. Finally, Healthline uses the Adnx Pixel, developed by the software company Xandr, which was acquired by Microsoft in 2021. Id. ¶¶ 49-50. Like the other Pixels, the Adnx Pixel allows companies to sell advertising space on their website by using the Adnx pixel to receive, store, and analyze information collected from website visitors. Id. ¶ 52. The Adnx pixel is installed on Healthline’s websites and sends the user’s IP address to Xandr, which stores it in a user’s IP address. Id. ¶ 54. Healthline knowingly installed the Pixels. Id. ¶ 62. In 2022, Healthline was sued for violations of the Video Privacy Protection Act, 18 U.S.C. § 2710, et seq., based on its use of the Meta Pixel on its website. Id. ¶ 57. Healthline also recently announced a $1.55 million settlement with the Attorney General of California relating to allegations that Healthline’s online tracking technology, including pixels, violated the California Consumer Privacy Act (“CCPA”). Id. ¶ 58. “Healthline allows online trackers, like cookies and pixels, to communicate data about readers to advertisers and other third parties. Healthline shared data that could uniquely identify the consumer, in addition to the title of the article they were reading.” Id. ¶ 59 (quoting California Attorney General’s press release on the settlement). Plaintiff Daniel Gliksman visited Healthline’s website numerous times. Id. ¶ 63. During the last year, Gliksman searched for and viewed articles regarding sensitive health conditions on Healthline.com, including , among other topics. Id. ¶ 9. After Gliksman searched Healthline’s website, he received advertisements for various exercise programs and medical studies related to . Id. ¶ 68. B. Procedural Background Gliksman filed suit against Healthline on December 2, 2024. Dkt. No. 1. On February 27, 2025, Healthline filed a motion to dismiss Gliksman’s complaint. Dkt. No. 21. On August 14, 2025, the Court granted Healthline’s motion to dismiss with leave to amend because Gliksman failed to adequately allege he had Article III standing. Dkt. No. 39.2 On September 11, 2025, Gliksman filed an amended complaint. Dkt. No. 44. The amended complaint brings two claims: (1) violation of California’s Invasion of Privacy Act (Cal. Penal Code § 638.51) and (2) violation of California’s Invasion of Privacy Act (Cal. Penal Code § 631(a)). Id. On October 2, 2025, Healthline filed a motion to dismiss, arguing that Gliksman lacked Article III standing and failed 2 On August 27, 2025, Healthline filed a motion to stay discovery pending resolution of its to state a claim under Federal Rule of Civil Procedure 12(b)(6). Dkt. No. 51. Gliksman filed an opposition on December 23, 2025, Dkt. No. 56, and Healthline’s reply followed on November 20, 2025, Dkt. No. 57. A. 12(b)(1) “To satisfy Article III’s case or controversy requirement, a plaintiff must establish that [they] ha[ve] standing to invoke the jurisdiction of the federal courts.” Bowen v. Energizer Holdings, Inc., 118 F.4th 1134, 1142 (9th Cir. 2024) (citing TransUnion LLC v. Ramirez, 594 U.S. 413, 423 (2021)). Article III standing requires a showing of an injury in fact that is traceable to the challenged conduct and redressable by a favorable ruling. See Spokeo, Inc. v. Robins, 578 U.S. 330, 338 (2016) (citing Lujan v. Defenders of Wildlife, 504 U.S. 555, 560-61 (1992)). “Only those plaintiffs who have been concretely harmed by a defendant’s statutory violation may sue that private defendant over that violation in federal court.” TransUnion LLC v. Ramirez, 594 U.S. 413, 427 (2021) (emphasis in original). A challenge to standing under Rule 12(b)(1) can be facial or factual. A facial attack presumes “the truth of the plaintiff’s allegations but asserts that they ‘are insufficient on their face to invoke federal jurisdiction.’ ” Leite v. Crane Co., 749 F.3d 1117, 1121 (9th Cir. 2014) (quoting Safe Air for Everyone v. Meyer, 373 F.3d 1035, 1039 (9th Cir. 2004)). A factual attack “co
