Guaranteed Privacy, Strong Encryption, Open Source
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.
Chat Anonymously: No Phone Number Required
Each user generates a random Threema ID when setting up the app. Linking a phone number or email address is optional.
No Collection of User Data, No Ads
Services that are financed by advertising collect user data in order to target their ads. Threema is not financed by advertising and does not collect user data.
100% Swiss Made and GDPR-compliant
Threema is a true Swiss company hosting its own servers in Switzerland. From software development to customer support, everything is done in-house. The service is fully GDPR-compliant.
Versatile Features, No Gimmicks
Privacy Is Worth Paying For
There is no such thing as a free lunch. If you don’t pay with money for a service, you pay with your data instead.
