More About Threema. The Secure Messenger
Threema is a messaging application that prioritizes privacy and anonymity for its users. This is achieved through various measures, such as not storing group memberships or contact lists on servers, immediately deleting messages after delivery, and encrypting local files on devices. These practices prevent the collection and misuse of personal information, in compliance with European privacy legislation.
The application also boasts rock-solid encryption for all forms of communication, including messages, voice and video calls, group chats, and even status messages. This is made possible through the use of the trusted open source NaCl cryptography library, and the generation and secure storage of encryption keys on users' devices. This ensures that only the intended recipient can access the messages, preventing backdoor access or copies.
Aside from its focus on privacy and security, Threema also offers a range of comprehensive features. Users can send text and voice messages, edit and delete sent messages on the recipient's end, make voice, video, and group calls, share videos, pictures, and locations, and send any type of file. The application also has a desktop app and web client for chatting from a computer, the ability to create groups and conduct polls, and the option to choose between a dark and light theme.
All of Threema's servers are located in Switzerland, and the software is developed in-house. This further ensures the privacy and security of user data. Additionally, each user is assigned a random Threema ID for identification, eliminating the need for a phone number or email address. This allows for full anonymity and the option to use Threema without giving up any personal information or creating an account.
The source code of the Threema app is open for review by anyone, and the company regularly commissions security audits by experts. Threema is also ad-free and does not collect user data, as it is not financed by advertising. In case of any questions or issues, users can consult the FAQs on the Threema website. Overall, Threema is a secure and private messaging option for those who value their online privacy.
PRIVACY AND ANONYMITY
Threema is designed from the ground up to generate as little data on servers as possible. Group memberships and contact lists are managed on your device only, and never stored on our servers. Messages are immediately deleted after they have been delivered. Local files are stored encrypted on your mobile phone or tablet. All this effectively prevents the collection and misuse of your personal information, including metadata. Threema is fully compliant with the European privacy legislation (GDPR).
ROCK-SOLID ENCRYPTION
Threema end-to-end encrypts all your communication, including messages, voice and video calls, group chats, files, and even status messages. Only the intended recipient, and nobody else, can read your messages. Threema uses the trusted open source NaCl cryptography library for encryption. The encryption keys are generated and safely stored on the users’ devices to prevent backdoor access or copies.
