Description

Threema is the world’s best-selling secure messenger and keeps your data out of the hands of hackers, corporations, and governments. The service can be used completely anonymously. Threema is open source and offers every feature one would expect from a state-of-the-art instant messenger. The app also allows to make end-to-end encrypted voice, video and group calls. Using the desktop app and the web client, you can also use Threema from your desktop.
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.

Threema is not only an encrypted and private messenger but also versatile and feature-rich.

To use it on Desktop, you need to have this app opren and phone unlocked. Promised Desktop 2.0 has not come. This has been an issue for many years. Because of this we stopped using the app completely and won’t migrate to Threema Work.

I’m using Threema from begging. Tried Session, Signal and etc. After the years Threema went a long way and in my subjective opinion it’s the best not just as personal IM, but business too of course. Well done Threema team 👌🏻👌🏻👌🏻
