Description
Threema is a Swiss instant messenger that was built from the ground up with security and data privacy in mind.
For one thing, state-of-the-art end-to-end encryption prevents anyone other than the intended recipient (including the service provider) from reading the messages users exchange. For another thing, it is not required to provide any personal information (such as a phone number or email address) to use Threema. In other words, the service can be used completely anonymously. Finally, Threema adheres to the Privacy by Design principles, which is to say that only as little metadata as possible is generated, and it is only stored for the shortest amount of time possible.
The service provider hosts its own servers in Switzerland.
