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.

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.

Find out how Threema stacks up against other messengers like WhatsApp, Signal, or Telegram in the comprehensive messenger comparison.

iOS users, rejoice! 🙌 The 4.8 update contains a whole host of new features and brings a breath of fresh air to Threema’s iOS app: threema.ch/bp/ios-48
