TRUST Your data stays yours

But is it safe?

We get it. Giving any app access to your email feels risky. Here's why Supermail is different.

100% Local Processing

Your emails never leave your browser. All scanning happens on your device, not our servers. We literally can't read your mail.

Google's Own Auth

We use Google OAuth, the same secure login Google uses. We never see or store your password. You're in full control.

Google Verified

We passed Google's rigorous security review for apps that access Gmail. They verified our data protection practices.
