SimpleX Chat crowdfunding is live! We are building the first messaging network that can't identify you – a decentralized, open-source network where only you decide who can connect to you and which servers to use, and nobody can know who you talk to. Yesterday SimpleX got to 1M+ downloads on Play Store (3M+ total). Thank you! We invite you to invest in SimpleX Chat and become part of building private and secure communications for all people. If you invest $500+, you also get SimpleX public name as a perk: - for 10 years if you invest until August 15 - for 5 years for early bird investors - for 3 years after that.

We are launching public SimpleX names - a name nobody can take from you. You can try a test SimpleX name with your channel or business in v7-beta. Read more in the blog post:

To ensure SimpleX Network independence, we created a non-profit SimpleX Network Foundation! The board: Heather Meeker (https://heathermeeker.com), Matt Odell @ODELL , Tadeas Kmenta (Flux), Evgeny Poberezkin (SimpleX Chat).

Consortium - SimpleX Network Consortium

An agreement governing the licensing and evolution of the SimpleX Network protocols.

Freedom of speech needs infrastructure that protects it by design - protocols, governance and funding. v6.5 release brings SimpleX Channels: a new model for online publishing built for participation privacy: - channel owners hold their own channel keys, - each channel uses multiple relays for reliability, - publishers can run their own chat relays, - channels can be added to our SimpleX Directory (https://simplex.chat/directory).

SimpleX Channels, SimpleX Network Consortium and Community Crowdfunding — to Preserve Freedom of Speech

We updated SimpleX Chat Privacy Policy and Conditions. What changed: Stronger privacy commitments: - explicitly states that preset servers do not log IP addresses. - you can verify clients and servers via reproducible builds. quantum-resistant end-to-end encryption. - messages are irreversibly removed from preset servers on delivery or after 21 days. - transparency commitment by client apps. New private one-time connection links and public addresses: - your profile data is encrypted on the server - only people with the link can access it, not the servers. - one-time link profile data is removed once the connection is established. Public channels (beta): - chat relays are used to deliver messages to channel subscribers. - chat relays cannot identify subscribers. Commit with the change:

A big news for SimpleX Chat privacy and security: Android apps released via GitHub and F-Droid are now 100% reproducible! It means that you can easily verify that the app is secure, even if the download site was hacked. From v6.5 our release process is: 1) build Android apps on two independent machines and confirm they are 100% identical; 2) cryptographically "sign" them; 3) add signature files to the release page so you can verify. v6.5 beta.3 release:
