Description

Threema is the world’s favorite 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 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 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.

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

• write text and send voice messages
• make voice calls (requires iPhone 5s / iOS 9 or above)
• share videos, pictures and locations
• send any type of file (pdf, animated gif, mp3, doc, zip, etc.)
• use Threema Web to chat from your Desktop
• create groups
• conduct polls with the unique poll feature
• choose between a dark and a light theme
• quickly and silently reply with the unique agree/disagree feature
• verify the identity of a contact by scanning their personal QR code
• use Threema as anonymous instant messaging tool
• synchronize your contacts (optional)

FULL ANONYMITY
Each Threema user receives a random Threema ID for identification. A phone number or email address is not required to use Threema. This unique feature allows you to use Threema completely anonymously – no need to give up private information or to open an account.

TRUSTED CONTACTS
We let users confirm trusted contacts with a QR code or a key fingerprint to prevent man in the middle attacks.

INDEPENDENT COMPANY
We are a 100% independent and self-financed company in the heart of Switzerland with its own servers and in-house software development. Switzerland is a country with some of the most user friendly privacy laws in the world.

Et ça fonctionne sur iPad !

C’est un point que vous ne trouvez pas nativement sous WhatsApp…!
J’aime bien l’app même si, effectivement, ça demande un poil de configuration mais revenons aux fondamentaux : votre idée est bien de naviguer en toute tranquillité, non ?!
La tranquillité, ça se paye. Et ce ne sont pas les quelques euros qui vont vous mettre sur la paille.

Une vrai app de messagerie !

La seule problématique avec cette application c’est comment faire comprendre aux gens l’intérêt de l’adopter. Mais après tout libre a chacun de faire ses propres choix... Continuez comme ça team Threema !!! PS 1 : un planning/agenda partagé serait intéressant PS 2 : des fonctionnalités pour la collaboration d’entreprise seraient bienvenues PS 3 : un peu d’IA dans le futur ?

Sécurité au rendez vous !

Appels chiffrés !😊 peux être bientôt les appels vidéos chiffrés ? La meilleure application sur le marché je recommande, en espérant que la confidentialité et le respect de la vie privée reste sa principale priorité. Serveur en suisse c'est super !⚡️ J'approuve le thème sombre. Un grand merci !😄
