Delta Chat @delta.chat · 26/05/2026Reminder: There are no accounts in the classic sense anywhere with #chatmail or #deltachat. It's all private profiles on end user devices which co-ordinate in a #p2p fashion. Chat profiles *use* email (relay) addresses for transporting messages through a […] [Original post on chaos.social] 063
Delta Chat @delta.chat · 05/05/2026We don't think any institution or state has the right to prevent families and friends from private chatting, physically or digitally. But the Cyber Authority China (CaC) seems to take offense: - they made Apple remove #deltachat iOS for mainland china - their […] [Original post on chaos.social] 1322
Delta Chat @delta.chat · 18/04/2026"Popularity is overrated" is an often occuring phrase in our circles. Which is of course nonsense because only what is popular, counts, right? Only what everybody else does is a valid choice, right? #deltachat #chatmail and #webxdc are used in private places and […] [Original post on chaos.social] 006
Delta Chat @delta.chat · 24/03/2026End-to-End Encryption is good but metadata protection counts as much. Names, group descriptions and memberships, avatars, who talks to whom ... Both #deltachat and #signal go to great length to protect all the metadata that WhatsApp grants itself gratuitously […] [Original post on chaos.social] 0935
Delta Chat @delta.chat · 20/03/2026The last two weeks saw a dev gathering in the black forest from several in #chatmail, #deltachat and #webxdc communiities, also joined by @n0iroh and @rpgp folks.

Delta Chat @delta.chat · 31/01/2026Ever wondering where the QR codes in #deltachat come from? each of them is handmade, as everything in delta :) #fosdem 0911
Delta Chat @delta.chat · 30/12/2025It's true: the more technical background and pre-conceptions you have, the more more likely you run into trouble with #deltachat 😂 Don't think so much! 😉 025
Delta Chat @delta.chat · 30/12/2025#39c3 .ending .. quite an enjoyable blast, and thanks to all the wonderful people just dropping by to say "thank you, it all works very nice for us"! 🥰 Certainly raised team spirits :) This year around, apart from one #chatmail relay setup workshop we didn't do […] [Original post on chaos.social] 013
Delta Chat @delta.chat · 12/12/2025Your chat profile/identity: a tar file. Your social web app: a zip file. chatmail.at and webxdc.org are spearheading ever new and more fun ways to deny power to servers and platform billionaires. Unlike classic email servers, #chatmail relays […] [Original post on chaos.social] 0312
Delta Chat @delta.chat · 11/12/2025#deltachat PSAs regarding the last 24 hours: 1) If you messaged someone about 20-30 hours ago, and did not get an expected response/receipt better "resend" (long-tap or right-click the message to resend). Unfortunately, not all queued messages at the crashing […] [Original post on chaos.social] 006

Delta Chat @delta.chat · 03/12/2025On the occasion of SimpleX and Session getting cryptocoin-donations/funding ... we won't hide that most delta contributors are pretty skeptical of cryptocoin-circles.

Delta Chat @delta.chat · 03/12/2025#Telegram has a nice and fast UI, granted. But the 1 billion people using TG are at risk because of its big central database that any state security service craves for. Moreover, several anonymization proxy-bot offerings were hacked in 2024, identifying […] [Original post on chaos.social] 107
Delta Chat @delta.chat · 26/11/2025#chatmail does secure email federation that works. Using lean "relay" servers that enforce metadata-minimized end-to-end encryption. There is a new little tool that checks whether two relays are interacting well for messaging, and how fast. You need a terminal […] [Original post on chaos.social] 024

Delta Chat @delta.chat · 19/11/2025Signal just released a "poll" feature with great fanfare, while all #deltachat apps already integrated a full suite of chat-shared apps, checklists, polls, shopping lists, calendar, editor + tons of games. Better, anyone can create new apps, eg as […] [Original post on chaos.social] 0211
Delta Chat @delta.chat · 19/11/2025Any data that is collected on servers will eventually leak or be abused otherwise. By design, no one can enumerate #deltachat profiles which are private and not published on any server. Conversely, #chatmail relays do not see or collect private data or metadata […] [Original post on chaos.social] 0212

Delta Chat @delta.chat · 13/11/2025Denmark and other EU governments still pursue #chatcontrol. They still want to permanently legalize client-side scanning but postponed making it mandatory.

Delta Chat @delta.chat · 25/10/2025Our project is one of constant exit planning and circumvention considerations ... as times and tech are getting more shitty.
