MLS: The Naked King of End-to-End Encryption

SimpleX Chat v6.3: new user experience and safety in public groups

We updated SimpleX Chat Privacy Policy & Conditions of Use. It's more Power to the People! 1. Added content license in groups, and stated that NO LICENSE is granted to the server operators or ourselves. We do not ask for ANY license to YOUR content! 2. Added the conditions of access to preconfigured servers via modified 3rd party applications. The previous policy version prohibited it, unintentionally. Thanks to the users developing apps for suggesting it! 3. Clarified some definitions: - "aggregate statistics" explicitly excludes any stats that can be related to particular users. - the content that can be removed changed from "identified illegal content" to "illegal content identified in publicly accessible resources". These changes do not change how we work: we never had user-related statistics, and we technically and legally cannot access private chats. Our privacy policy also: - includes a commitment to run the published code, - re-confirms the absence of any compulsory requests. Thanks to all users for suggesting these changes. The full text:

SimpleX network: cryptographic design review by Trail of Bits, v6.1 released with better calls and user experience.

v6.1-beta.0 is released with support for SOCKS proxies both in iOS (via TestFlight) and Android (via Github releases as direct APK download: https://github.com/simplex-chat/simplex-chat/releases/tag/v6.1.0-beta.0). You can host your own SOCKS proxy (this one looks good: https://github.com/heiher/hev-socks5-server) or you can try ours, if you use preset servers (it won't allow connecting to any other servers directly, but you can still send messages to anybody who uses other servers): Address: 139.162.173.97 Port: 443 Username: user Password: YJHolWSzTfOny7es
