Threema

🇨🇭

by Threema

Threema is a Swiss encrypted messenger founded in 2012 by Manuel Kasper in Pfäffikon, Switzerland. Unlike most messaging apps, Threema requires no phone number or email to register — users get a random Threema ID, enabling truly anonymous communication. All messages, calls, and files are end-to-end encrypted, and metadata is minimized by design. Threema is fully open source and has been independently audited. It's widely adopted in German-speaking countries and used by the Swiss government and military.
