Why lock Lock Master Photo Album?
Lock Master Photo Album is a private photo app, the kind of app that tends to hold personal information 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.
Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.
A lock answers one question — who can open the app on this iPhone. It does not change what Lock Master Photo Album sends to its developer; for that, see Lock Master Photo Album's full privacy report.
