Threema the Swiss messenger that puts security and privacy first

Since Brazil is becoming the opposite of a free country, we just switched from Telegram to Threema and are convinced that it will help us to saveguard privacy.

Guaranteed Privacy, Strong Encryption, Open Source. That is Threema's promise.

Threema is the instant messenger designed to generate as little user data as possible. All communication is end-to-end encrypted, and the app is open source. Servers are in Switzerland.
