A class action lawsuit alleging the Meta pixel illegally collected patient data will move forward.

A federal judge has certified four classes of Facebook users in a class action lawsuit against Meta Platforms Inc., alleging that Meta's Pixel tracking code illegally collected patients' private health information from hospital and doctor websites without consent. The lawsuit covers Facebook users from June 17, 2018, to the present, claiming that Meta matched the collected data to Facebook users for system improvement and advertising. The certified classes are bringing claims rooted in privacy and contract law, including breach of contract and intrusion upon seclusion, seeking damages and a court order to prevent further data collection.
