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

Voice and messages errors

Threema users on

We encounter the following recurring errors: - In the case of voice calls, it does not ring, the caller cannot answer the call. - The other party receives the sent messages, but cannot answer. These problems are only solved by restarting the phone temporarily. On iPhone 13 and 11. Thank you for your help!

Shortcomings

Gyusz1976 on

Followings are missing to be the best one: - Self deleting messages - set expiration timer... - separating with difference colorization of chat partners in dark mode

Nagyon jó!

Nagyon jó csak a magyaroknak nem nagyon van rá pénzük ezért kevés az ember :S

Biztonságos és robosztus

Két éve használom. Az egyetlen gond vele, hogy kb. 5 évvel megelőzte a korát. A küldött üzenetek, csatolt file-ok úgy vannak titkosítva hogy azok a szerveren sem olvashatóak.

Végre egy normális IM

Évek óta használom, tökéletesen működik, a zavaró inkább az, hogy túl kevesen költenek szaros néhány garast ara, hogy ezt használják kommersz szarok helyett.
