App of the Day: @SimpleXChat - a private and encrypted messenger without any user IDs. Make a private connection via link / QR code to send messages and make calls. -> privacytools.io/app/simplex-ch…
Big thank you to @trailofbits for finding bugs and vulnerabilities in SimpleX Chat and submitting patches. SimpleX Chat is getting better every day!
Patch the Planet is our joint initiative with @OpenAI to help maintainers strengthen critical open-source software. In one week, we used Codex and GPT-5.5-Cyber to find hundreds of bugs inside OSS like cURL, Python, and the Go project. 37 patches merged, with more in flight. 🧵

Alain Brenzikofer @brenzi5 will talk at @Web3summit on June 19: SimpleX Community Credits: Making Privacy Profitable. Big thank you to @Web3foundation for the opportunity and for their help with our proof of concept on @Polkadot that Alain built - the vision is getting real! 👇
🆔Starmer's plans for child-locked devices is a Trojan horse for digital ID "The only way to escape Starmer’s Great British Firewall and get regular internet access is to undergo a digital ID check on the device to register yourself as an adult user. Convenient, perhaps, for a Prime Minister who has failed to get a digital ID system through the front door" - @silkiecarlo
@NivalCat @HeatherMeeker4 @TadeasKmenta @epoberezkin The foundation is non-profit. SimpleX Chat remains a commercial entity. Both are needed. Network protocols governance will gradually transition from company to consortium over coming years, as the protocols stabilize. The motivation is explained here: github.com/simplex-chat/s…
To ensure SimpleX Network independence, we created a non-profit SimpleX Network Foundation! The board: @HeatherMeeker4, Matt Odell (primal.net/odell), @TadeasKmenta, @epoberezkin simplexnetwork.org/consortium.html
Scanning devices is not a solution for safety - it's a backdoor that endangers everybody. It violates many laws, including in the UK, and is technically unenforceable. Such ideas were rejected before and must be rejected now.

@unstoppablebyhs Let's add to this page: simplex.chat/links/
@aniiland @TheSynapseX This is a complex problem, that no messaging app has solved without compromising users' security or privacy. We understand that it is important for the users, and has to be provided at some future point, to improve usability. We commented more here: simplex.chat/faq/#why-cant-…
Most private messengers encrypt the message. @SimpleXChat hides the identity, the graph, and — with Tor — the route. No phone number. No username. No user ID. No central social graph. Optional Tor/Orbot routing. That’s why SimpleX is different. Signal protects your chats. Telegram hides only Secret Chats by default. XChat encrypts content but still leaves metadata visible to X. SimpleX goes deeper: The server doesn’t know who you are. The network doesn’t need your phone number. And with Tor, even the route can be harder to trace. Encryption protects the message. SimpleX protects the map.
We just created the page with the links to 240+ community articles, posts, videos, podcasts, guides in 20+ languages about SimpleX Chat: simplex.chat/links Big thank you to everybody who promoted what we build. It would not have happened without you.
Decentralized architectures, like Session or Tor, cannot guarantee via technology alone that different nodes are run by different entities, and that they don't collude and don't sell or exchange metadata. As Eric Hughes put it - "code alone doesn't cut it". As clients decide which nodes to route traffic through, they need to know which node is owned by which entity. Simply selecting random nodes is insufficient even if one operator runs 2-3% of nodes, and the real concentration in decentralized networks is much higher than that. If you know a technical design that can enforce node independence and prevent metadata sharing - please explain. We don't think it's possible.
We updated SimpleX Chat Privacy Policy and Conditions: - Stronger privacy commitments from operators and apps. - New one-time links and public addresses. - Public channels released in v6.5 (beta). See all changes via the link in the comment 👇

Our support contact in the app (Ask SimpleX team) switched to the new support bot 🤖🚀 It lets users send questions about SimpleX Chat to @grok (opt-in), or to connect to the team. We will publish the guide how anybody can use this bot for customer support later this month.
