Threema is an instant messaging app from Switzerland that focuses on user privacy and data security. It was first released in 2012 and aims to provide a secure and anonymous communication platform.
Key features
- End-to-end encryption: Threema encrypts all communication content (including messages, voice calls and video calls) end-to-end, ensuring that only the sender and receiver have access to the information.
- Anonymous use: Users are not required to provide a mobile phone number or email address, but are identified by a randomly generated Threema ID, ensuring complete anonymity.
- Privacy: Threema is designed to minimise the amount of data stored on the server, with group memberships and contact lists saved only on the user's device and deleted immediately after the message is sent.
- Versatility: In addition to basic messaging, Threema supports a wide range of features such as file sharing, group chat, voice and video calls, and more.
