Meta launched an "Incognito Mode" for WhatsApp and its Meta AI app on May 13, 2026. This feature allows private conversations with Meta AI where no data is stored; chats are permanently deleted when the session ends. Powered by the new Muse Spark model and a secure private infrastructure, it ensures privacy without breaking end-to-end encryption. The move addresses growing user concerns over AI data retention and legal risks, positioning Meta ahead in the compliant AI integration race. A "Side Chat" feature for private AI use in group chats is also in development.
