Why lock App Lock Locked Apps Vault?
App Lock Locked Apps Vault's privacy label lists location — the kind of data you would not want on screen if someone borrows your unlocked phone. Private-photo apps promise to keep pictures out of your main library. The label shows what leaves the phone; it cannot show whether the hiding is a real lock or just a separate folder.
Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.
A lock answers one question — who can open the app on this iPhone. It does not change what App Lock Locked Apps Vault sends to its developer; for that, see App Lock Locked Apps Vault's full privacy report.
