Meta Hatch privacy: what we know
Any AI agent that books flights, orders food, and shops for you has to see a lot. The privacy question is not just what it sees in the moment, but what it keeps, what it learns, and whether the version of you it builds can ever leave.
What Hatch will almost certainly see
- Your requests. Every booking, purchase, and search you ask it to perform.
- Connected accounts. Payment methods, addresses, calendars, and travel accounts you link.
- Behavior inside Meta apps. Messages, posts, and activity across Instagram, WhatsApp, Messenger, and Facebook, depending on permissions.
- Feedback and corrections. What you fix, reject, or repeat — all signal for future recommendations.
What is less clear
As of late August 2026, Meta has not published Hatch's final privacy terms. We do not know exactly how long inferred preferences will be retained, whether they will be used to train models, or how complete a deletion will be. Meta's track record with other AI products suggests user content can be used for training unless a user opts out in an eligible region.
The real privacy question
Privacy is not only about who can read your messages. It is about who owns the model of you that gets built from them. An agent inside a platform that already monetizes attention and behavior is incentivized to make that model more useful to the platform over time. That is not a conspiracy; it is the business model.
A memory vault inverts that. You are the customer, not the product. The vault's incentive is to keep your data safe, portable, and under your control — because that is the only thing it sells.
