Global Lawsuit Challenges Meta’s Claims About WhatsApp Privacy

By  |  January 25, 2026

An international group of plaintiffs has filed a lawsuit against Meta Platforms Inc., accusing the company of misleading users about the privacy and security of WhatsApp messages, according to Bloomberg. The case, lodged Friday in U.S. District Court in San Francisco, centers on the social media giant’s repeated assurances that WhatsApp conversations are protected by end-to-end encryption.

    Meta has long promoted this form of encryption as a cornerstone of WhatsApp’s design, telling users that messages can only be read by the sender and recipient. The app also displays in-chat notices stating that “only people in this chat can read, listen to, or share” messages, per Bloomberg.

    The plaintiffs argue that these representations are deceptive. In their filing, they allege that Meta and WhatsApp “store, analyze, and can access virtually all of WhatsApp users’ purportedly ‘private’ communications,” claiming the companies have misled billions of users worldwide, according to Bloomberg.

    The lawsuit brings together individuals from Australia, Brazil, India, Mexico, and South Africa. They contend that Meta retains the substance of user messages and that company employees are able to access that content, directly contradicting the company’s public statements, per Bloomberg.

    Meta has strongly rejected the allegations. A company spokesperson described the case as “frivolous” and said Meta intends to seek sanctions against the plaintiffs’ attorneys. “Any claim that people’s WhatsApp messages are not encrypted is categorically false and absurd,” Andy Stone, a Meta spokesperson, said in an email. “WhatsApp has been end-to-end encrypted using the Signal protocol for a decade. This lawsuit is a frivolous work of fiction.”

    The complaint also references unnamed “whistleblowers” who allegedly helped reveal internal practices, though no details about their identities or roles were provided, according to Bloomberg.

    Attorneys for the plaintiffs are asking the court to grant class-action status, which could expand the case to represent WhatsApp users around the world. Several lawyers from Quinn Emanuel Urquhart & Sullivan and Keller Postman are listed in the filing but did not respond to media inquiries. Another attorney for the plaintiffs, Jay Barnett of Barnett Legal, declined to comment Saturday night, per Bloomberg.

    The case adds to ongoing scrutiny of how large technology companies handle user data and whether their privacy promises match their internal practices.
