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.

Ratings and Reviews
Good app, but hide stale contacts is the dumbest feature I have seen in a while
This is a very nice messaging app with excellent privacy features, but the feature to „inactivate“ and hide contacts that have not been on there is really the dumbest thing I’ve seen in a while, and I doubt it’s tested with users. From my perspective:
1) It will certainly hurt uptake of the app: Most people who decide on whether or not to use the app will check how many people are on there. Seeing only a few contacts will discourage them. See network effect.
2) Having „(inactive)“ display next to your name for 24 hours after you started using the app again just feels plain weird in an app that is boasting it’s privacy features. Who says I‘m inactive? And why doesn’t the very action of sending a message determine activity? Also, having to chat with „inactive“ contacts with the constant reminder that they are deemed inactive (it shows in the chat and in notifications) is an unpleasant experience.
Great app, but has problems now
I have used the app for 4 years. Has always been the got to app for myself and friends for private messaging. Since the last update though, messages are not uploading properly for any of us. Often we when we see each, we complain that the other hasn’t responded. In actual fact, out messages sometimes don’t load onto the server from our phone. Apart from that, very happy with it.

Well maintained and secure
I’ve been using Threema for over five years. It’s constantly improved, secure and has a great feature set. I’ve never had it crash. Paying for it is a great, sustainable idea. I recommend anyone serious about privacy consider using Threema.
