Meta Muse Enrolls Users by Default in Data Collection for AI Model Training

Meta has launched Muse, a personal AI agent that collects user data for AI training via an opt-out system enabled by default, raising fresh privacy concerns about the company's data practices. The app, released in September 2026 and available in the U.S., is designed to manage email, calendars, payments, shopping, health tracking, smart home devices, and other personal tasks. Users can choose which apps to connect, but their conversations and interactions automatically feed into Meta's model training pipeline unless they manually disable the setting in Muse's data controls.
