WhatsApp privacy lawsuit filed

A proposed class action filed in California says WhatsApp, Meta, and Accenture let employees or contractors read, store, or share supposedly private chats, even while WhatsApp told users that only the sender and recipient could read them. The complaint was filed on March 27, 2026, and was reported publicly on April 1. (classaction.org) The plaintiffs, Brian Y. Shirazi and Nida Samson, say the problem dates back to April 5, 2016, when WhatsApp rolled out end-to-end encryption using the Signal Protocol after Meta bought the app in 2014. Their claim is that WhatsApp advertised a locked mailbox while allegedly keeping a spare key inside the company. (classaction.org) End-to-end encryption is the part of the story that matters most here. It means a message should be scrambled on your phone and unlocked only on the other person’s phone, so the company carrying it is supposed to be like a postal truck that moves sealed envelopes without opening them. (about.fb.com) WhatsApp has spent years making exactly that promise. Its public help pages say no one outside the chat, “not even WhatsApp,” can read or listen to messages, and Meta repeated on April 10 that WhatsApp has used the Signal Protocol for a decade. (timesofindia.indiatimes.com) The lawsuit says the alleged opening was not the encryption system itself but a review process for messages flagged for fraud or abuse. According to the complaint, that process let Meta staff, Accenture contractors, and possibly other third parties bypass the privacy users thought they had. (classaction.org) Meta’s answer was blunt. In a public response on April 10, WhatsApp called the lawsuit’s claims “categorically false and absurd” and said messages cannot be read by anyone other than the sender and recipient. (timesofindia.indiatimes.com) That denial did not keep the story inside the courthouse. Elon Musk replied “Can’t trust WhatsApp,” and Telegram founder Pavel Durov used the fight to attack a rival service that competes directly with Telegram for private messaging users. (timesofindia.indiatimes.com, firstpost.com) The timing is awkward for Meta because WhatsApp is no longer just a chat app. On Meta’s January 28, 2026 earnings call, the company said more than 2 billion people use WhatsApp daily, and it said Family of Apps “other revenue” rose 54 percent to $801 million in the fourth quarter of 2025, driven in part by WhatsApp paid messaging. (s21.q4cdn.com, investor.atmeta.com) Meta has also been adding more business tools to WhatsApp, including calling and voice features for the WhatsApp Business Platform that it announced in July 2025. That means the same app now carries family gossip, doctor reminders, shipping updates, and sales chats, which raises the stakes when a privacy claim lands. (about.fb.com) There is another wrinkle that often gets lost in arguments about encryption: backups. Meta said in October 2025 that it was making encrypted WhatsApp backups easier with passkeys, which is a reminder that message privacy depends not just on the chat pipe but also on where copies are stored. (about.fb.com) So the case is now testing two different things at once. One is a legal question about what WhatsApp employees or contractors could actually access, and the other is a trust question about whether a privacy promise still counts if exceptions, review systems, or storage paths are too hard for ordinary users to see.
