Description
SimpleX - the first messaging platform without user identifiers of any kind (not even random numbers) - 100% private by design!
Security assessment by Trail of Bits: https://simplex.chat/blog/20221108-simplex-chat-v4.2-security-audit-new-website.html
SimpleX Chat features:
- quantum resistant end-to-end encrypted messages, with editing, replies and deletion.
- disappearing messages with opt-out per contact/group.
- message reactions.
- delivery receipts, with opt-out per contact or group.
- multiple chat profiles, with hidden profiles.
- app access and self-destruct passcodes.
- incognito mode - unique to SimpleX Chat.
- sending end-to-end encrypted images and files.
- voice messages up to 5 minutes – also end-to-end encrypted.
- "live" messages – they update for all recipients as you type them, every few seconds - unique to SimpleX Chat.
- single-use and long-term user "addresses".
- secret chat groups - only group members know the group exists and who is the member.
- end-to-end encrypted audio and video calls.
- connection security code verification, for contacts and group members – to protect from man-in-the-middle attacks (e.g. invitation link substitution).
- end-to-end encrypted push notifications (they contain only encrypted meta-data, not the actual content).
- encrypted portable chat database - you can transfer your chat contacts and history to another device.
- all local files and media are encrypted by default.
- animated images and "stickers" (e.g., from GIF and PNG files and from 3rd party keyboards).
SimpleX Chat advantages:
- privacy of your identity, profile, contacts and metadata: unlike any other existing messaging platform, SimpleX uses no phone numbers or any other identifiers assigned to the users - not even random numbers. This protects the privacy of who you are communicating with, hiding it from SimpleX platform servers and from any observers.
- complete protection against spam and abuse: as you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address.
- full ownership, control and security of your data: SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received.
- decentralized proxied peer-to-peer network: you can use SimpleX Chat via your own relay servers and still communicate with people using pre-configured or any other SimpleX relay servers.
- fully open-source code.
You can connect to anybody you know via link or scan QR code (in the video call or in person) and start sending messages instantly - no emails, phone numbers or passwords needed.
Your profile and contacts are only stored in the app on your device - relay servers do not have access to this information.
All messages are end-to-end encrypted using open-source double-ratchet protocol; the messages are delivered via relay servers using open-source SimpleX Messaging Protocol.

Très prometteuse !
Une version pour IPad serait géniale, merci . Dommage que cela ne soit pas plus friendly pour les systèmes GNU/Linux et Windows. Une version web/desktop peut-être ?
Très Bonne application
Juste un bug , je pense qu’il faut séparer les contacts et les conversations, pour éviter de supprimer les contacts en croyant supprimer l’historique.
Ma numéro 1
Simplex est devenue en l'espace de quelques mois une application de messagerie sécurisée stable et incroyablement bien pensée. Elle surpasse toutes les autres applications dites "sécurisées" par son fonctionnement, je vous invite à lire les informations à ce sujet sur le site web. Merci à ces développeurs de continuer de se battre pour un mondre libre et sans censure.
Très prometteuse !
Je trouve que cette application de chat offre ce qui se fait de mieux en terme de sécurité, d’anonymat et de chiffrage. Tout est fait pour le respect de la vie privée. Il y a vraiment plein de bonnes idées, par contre elle souffre un peu de sa jeunesse mais les petits bugs sont vites corrigés. J’espère qu’ils trouveront un moyen de durée car la concurrence est dure!
