Why lock temp mail - 1secmail?
temp mail - 1secmail 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.
Social apps are built around identity and contacts, so data linked to you is nearly universal. Tracking and contact upload are the settings worth checking.
