Whistleblowers have raised serious concerns about WhatsApp’s privacy, alleging that its parent company, Meta, can access private chats despite its promises of end-to-end encryption.
The claims are detailed in a lawsuit filed in a US court, which argues that users were misled about the true level of privacy offered by the messaging service.
According to the filing, Meta promoted WhatsApp as a fully private platform where only senders and recipients could read messages. The whistleblowers allege this representation does not fully reflect how message data is handled internally.
The lawsuit claims that billions of users worldwide relied on these assurances when choosing the platform for personal and sensitive communication.

End-to-end encryption is designed to prevent third parties, including service providers, from accessing message content. The allegations raise questions about whether WhatsApp’s implementation meets the expectations set by its public statements. Meta has not admitted wrongdoing, and the claims have yet to be tested in court.
The case adds to ongoing global scrutiny of how major technology firms manage user data and communicate privacy protections.

Legal experts note that the outcome could influence how digital privacy claims are regulated and enforced in the future.
The lawsuit remains under review, and no court ruling has been issued. Meta has previously stated that WhatsApp uses strong encryption and prioritises user privacy. Further details are expected as the legal process unfolds.
