📖What it means

The principle that no user's data is ever shared with another user — including with the admin. The only exception the constitution allows is a genuine hazard to a person or to the system. This is a principle, so no policy or convenience may erode it.

📖Easily confused with

[{"term": "Confidential", "distinction": "User isolation fences one PERSON's data from other people; confidential fences an app's records so each AGENT sees only its own."}]

📖Also called

- data isolation
- user privacy
- no cross-user access
