Threema is a mobile messaging app in which security and privacy issues come first. Thanks to true end-to-end encryption, you can be sure that your messages can only be read by you and the person to whom you wrote them.
You can use Threema completely anonymously, without transmitting any personal information, such as phone numbers or email addresses. Your messages will be deleted from our servers immediately after they are delivered. In this way, you are fully protected from the unauthorized use of your personal data.
Threema performs end-to-end encryption of any type of transmitted data – text, files and even statuses. For this, an open source cryptographic library is used. Keys, unlike Telegram, are stored on users’ devices, and not on the server, which allows for security. The main idea of the messenger is to generate data without the participation of the server side. Most of the actions are performed on user devices. Even local files on the smartphone are encrypted, which is designed to block the collection of personal information without the consent of the owner. In terms of functionality, Threema is a regular messenger with the ability to transfer files. You can use group chats, verify the authenticity of contacts by scanning personal codes, choose one of two themes, etc.
