Why lock Safe Mail for Gmail Free?
Safe Mail for Gmail Free is a secure email app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Email apps see every message and contact. Third-party mail clients may route mail through their own servers to offer features like push or AI summaries.
Business apps often handle other people's data — clients, colleagues and customers — so what they collect can affect more than you.
A lock answers one question — who can open the app on this iPhone. It does not change what Safe Mail for Gmail Free sends to its developer; for that, see Safe Mail for Gmail Free's full privacy report.
