Persistent personal context can include preferences, previous conversations, documents, relationships, routines, and unfinished tasks. It can reduce repeated explanations and help an assistant provide continuity across sessions.
Persistence increases privacy and security consequences because a growing context store can reveal a detailed picture of a person's life. Users need visibility, control, correction, deletion, access boundaries, and clear rules governing how the information is used.

Persistent personal context is information an AI remembers about a user for later conversations. It can help the system continue earlier work and avoid asking for the same preferences every time.
For example, an assistant might remember a user's dietary needs and an unfinished travel plan. That can be convenient, but the user should be able to see, correct, and remove the information and know who else can access it.
