Revocation is where personalization becomes accountable.
Consumer AI products have spent the last wave teaching users that remembered context makes an assistant more useful. A travel preference helps with booking, a pantry habit helps with grocery planning, and a work style helps with task delegation. But as soon as memory becomes useful, it also becomes sensitive. Users need a way to remove remembered facts without wondering whether the system merely hid them from view.
The strongest personal agents will treat revocation as a first-class event. A user should be able to say “forget that address,” “remove that card photo,” or “do not use my job search context anymore,” and receive a compact explanation of what changed. That explanation is not legal theater. It is product evidence that the agent respects the user’s boundary.
