Proton Mail: Encrypted Email

Private email for everyday communication

Proton Mail: Encrypted Email is an email app for people who want stronger privacy around their messages without giving up familiar inbox tools. It uses end-to-end and zero-access encryption, so messages are protected before they reach Proton’s servers. That makes it a suitable choice for personal correspondence, work messages, and anyone who prefers a privacy-focused alternative to mainstream email services.

Security that stays out of the way

The app is designed to keep encryption in the background rather than make email feel technical. You can send password-protected messages to people who do not use Proton Mail, extending secure communication beyond your own inbox. Its use of open-source cryptographic libraries also gives security-conscious users more visibility into the technology behind the service.

Tools for keeping an inbox usable

Privacy is paired with practical organization features, including labels, folders, and customizable swipe gestures. Multiple accounts can be managed from the same app, while the interface follows the layout familiar from other mobile email clients. Users moving from another provider can also use Proton Easy Switch to import messages, contacts, and calendars from supported services.

A widely used communication app

Proton Mail is developed by Proton AG and listed in the Communication category. It has more than 10,000,000 installs and a rating of 4.26 from 83,255 reviews. Those figures place it among the more established options for Android users looking for encrypted email with conventional inbox management.
