Threema. The Secure Messenger

Threema GmbH
Threema is the world’s best-selling secure messenger and keeps your data out of the hands of hackers, corporations, and governments. Threema can be used completely anonymously, allows to make end-to-end encrypted voice and video calls, and offers every feature one would expect from a state-of-the-art instant messenger. With Threema Web, you can also use Threema from your Desktop.

PRIVACY AND ANONYMITY
Threema is designed to generate as little data on servers as possible – this is a core part of our concept. 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 meta data. Threema is fully compliant with the European privacy legislation (GDPR).

HIGHEST ENCRYPTION STRENGTH
Threema encrypts ALL your communications END-TO-END including messages, voice and video calls, group chats, media files and even status messages. You can rest assured that only the intended recipient can read your chats, and nobody else – not even us. Threema uses the trusted open source NaCl cryptography library for encryption. The encryption keys are generated and safely stored on user’s devices to prevent backdoor access or copies.
