Legal Action Against University California San Francisco (UCSF) for Unauthorized Sharing of Health Data with Meta Platforms

Lowey Dannenberg, P.C. is actively prosecuting a case on behalf of individuals who used the University of California San Francisco Medical Center (also known as “UCSF”) website and/or patient portal to search for or obtain medical care, including searching for appointments and completing online intake forms.

UCSF operates over 20 locations in Northern California and elsewhere, including clinics, hospitals, and other facilities. The action is Doe v. Regents of the University of California, 3:23-cv-00598 (N.D. Cal.) and alleges that individuals who used UCSF’s website and/or patient portal had their private health data shared with and used by Meta Platforms, Inc.—one of the largest advertisers in the world—without their knowledge or permission.
