The introduction of AI features on WhatsApp processes user data outside of encryption, while Meta faces a US lawsuit and strict EU regulations.
WhatsApp is facing the biggest conflict in its history: The messenger is integrating artificial intelligence – and thus calling into question its foundation of end-to-end encryption. At the same time, regulators in Europe and a lawsuit in the USA are increasing the pressure on parent company Meta. The boundary between private communication and data processing is blurring.
AI in chat: Data ends up on meta servers

Meta’s strategy fundamentally changes WhatsApp. New AI functions in beta versions organize chat histories and analyze messages. But this convenience comes at a price: every interaction with the AI is processed on Meta servers – outside the protected space of end-to-end encryption.

Sensitive information such as health or financial data that users share with AI is no longer private. Meta confirms that this data can be used to personalize content and advertising. There is currently no opt-out for users. The company refers to a “private processing” technology that is being developed and is intended to create a kind of digital vault for AI data.
Lawsuit and denial: Is encryption a “hoax”?
Confidence in WhatsApp’s core promise suffered another setback in January 2026. A lawsuit filed in U.S. District Court accuses Meta’s end-to-end encryption claims as misleading and false. Anonymous whistleblowers allegedly claimed that the company had access to the contents of private messages.
Meta vehemently rejected the allegations and described the lawsuit as “absurd” and “a frivolous fantasy.” The company announced legal action against the plaintiffs’ lawyers. Security experts expressed doubts about the technical feasibility of the alleged access. But public doubt about the promise of encryption has been sown.
EU regulators get involved
In Europe, the EU Commission is taking tough action against Meta. Since January 26, 2026, WhatsApp has been officially considered “Very large online platform” (VLOP) under the Digital Services Act (DSA). The trigger was the “Channels” function, which has over 45 million monthly users in the EU.
WhatsApp must now meet strict new obligations by mid-May 2026. This includes comprehensive risk assessments and measures to address systemic threats to privacy, the spread of illegal content and human rights.
In addition, an antitrust investigation has been ongoing since the end of 2025. The focus is on a new policy that prohibits third-party providers from offering their AI services via the WhatsApp Business Platform – while Meta’s own AI access remains unrestricted. The Commission is already considering interim measures to prevent “serious and irreparable harm” to competition in the AI market.
The new privacy: Users have to act themselves
The definition of privacy on WhatsApp is shifting. The focus is no longer just on encrypted chats, but also on metadata, business communications and AI training data. Conversations with companies can be less protected when traders use Meta’s AI for communication.

Meta responds with new user-controlled features. These include enhanced IP address protection for calls and “strict account settings” for high-risk users. An update is expected to follow by June 2026 that will enable registration using a user name instead of a telephone number – an important step against spam.
The future of WhatsApp’s privacy will be determined by ongoing litigation and compliance with new rules. For over a billion users worldwide, it is increasingly becoming their responsibility to stay informed and use advanced settings. The golden age of simple, secure communication may be over.
