Secure Communication for Individuals with Threema

Pay once, chat forever. No collection of user data. Open Source.

Thanks to consistent end-to-end encryption, no one other than the intended recipient can read transmitted messages, not even Threema as the service operator. It’s not required to provide any personal data whatsoever: If so desired, Threema can be used completely anonymously, i.e., without disclosing one’s phone number or email address. Threema was built from the ground up with data protection and privacy in mind (Privacy by Design), which is why only as little metadata as possible is generated when using the service.

Threema is 100% Swiss Made, hosts its own servers in Switzerland*, and, unlike US services (which are subject to the CLOUD Act, for example), it is fully GDPR-compliant.

Security and Privacy by Design

Threema was designed from the ground up with security and privacy in mind. Since day one, the restraint on metadata has been our guiding principle. For where there is no data, no data can be misused. Threema’s server only assumes the role of a switch: After a message has been delivered to its recipient, it will be permanently deleted at once.

The focus on security and privacy protection is also reflected in the implementation of numerous particular features, such as profile pictures, Threema calls, and the desktop app / web client.

Threema is committed to full transparency, and for this reason, the apps are open source. On top of that, renowned experts are regularly commissioned to conduct comprehensive security audits.
