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.

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

FULL ANONYMITY

OPEN SOURCE AND AUDITS
The source code of the Threema app is open for everyone to review. On top of that, renowned experts are regularly commissioned to conduct systematic security audits of Threema’s code.

The best chat app

Wolf country 11111 on

This app is the best chat app for encryption & offers the same plus more options than any chat app it is beyond a 5 star rating in my opinion. It only has no option to hide or unhide active status which I feel for privacy reasons is good plus if trust 100 than I feel its a no need to know option. Wish I found this app long ago 👍👍👍

I like Threema their support is excellent most of all though l like their desire for privacy.I don’t understand why more people aren’t using it,maybe they need to advertise more and possibly have a phone book for those of us who are already on threema.
