Why lock Temp Mail - Temporary Emails?
Temp Mail - Temporary Emails 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.
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.
