Introducing Encrypted SMS for your Mobile device

Swiss Privacy
Data Security and Neutrality

ProtonSMS is incorporated in Switzerland and all our servers are located in Switzerland. This means all user data is protected by strict Swiss privacy laws.

End-to-End Encryption
Automatic SMS Security

All text messages are secured automatically with end-to-end encryption. This means even we cannot decrypt and read your text messages. As a result, your encrypted text messages cannot be shared with third parties.

Anonymous Text Messages
Protect Your Privacy

No personal information is required to create your secure SMS account. By default, we do not keep any IP logs which can be linked to your anonymous SMS account. Your privacy comes first.


Open Source
Free Secure SMS

We believe text message privacy should be available to all. That’s why our code is open source and basic ProtonSMS accounts are always free. You can support the project by donating or upgrading to a paid account.


Easy to Use
Security without the hassle

ProtonSMS can be used on any device without software install. ProtonSMS secure SMS accounts are fully compatible with other email providers. You can send and receive text messages normally.


Modern Inbox Design
Security with Productivity

The ProtonSMS inbox is optimized for productivity. Each detail within our secure SMS service is optimized to help you better read, organize, and send text messages.
