Threema is an instant messenger designed to generate as little user data as possible. All communication is always end-to-end encrypted. When setting up the chat app, each user generates a random Threema ID. Linking a phone number or email address is optional. Free online services are often financed by using user data for advertising. For example, WhatsApp collects metadata, which isn't compatible with privacy protection. Threema is financed by the price of the app and does not collect user data. Hide particularly sensitive chats, and lock them with a PIN or biometric data. Place calls without revealing your phone number. Threema calls are end-to-end encrypted and thus tap-proof. They impress with crystal-clear voice quality and brilliant video quality. Threema is a true Swiss company hosting its own servers in Switzerland.
