Threema. The Secure Messenger

Threema is a messaging application that prioritizes privacy and anonymity for its users. This is achieved through various features and practices that limit the collection and misuse of personal information. The app is fully compliant with European privacy legislation and uses rock-solid encryption to ensure that only the intended recipient can read messages. Threema also offers a range of comprehensive features, including text and voice messaging, voice and video calls, file sharing, and group chats.

One of the key aspects of Threema's privacy measures is its minimal data storage on servers. Group memberships and contact lists are managed on the user's device and messages are immediately deleted after delivery. Local files are also encrypted on the user's device, preventing backdoor access or copies. Additionally, Threema's servers are located in Switzerland and the software is developed in-house, further ensuring the security and privacy of user data.

Threema also offers full anonymity to its users. Each user is assigned a random Threema ID for identification, eliminating the need for a phone number or email address. This allows users to use the app completely anonymously without giving up any private information or creating an account. Threema also offers the option to synchronize contacts, but this is not required for the app to function.

The app's source code is open for review by anyone, and Threema regularly commissions security audits to ensure the safety of its users' data. Threema is also ad-free and does not collect user data for advertising purposes. In case of any questions or issues, users can consult the app's FAQs or contact support for assistance. Overall, Threema is a secure and private messaging option for those who value their online privacy.
