@jwildeboer curious why you are recommending Silicon Valley single choke point app Signal, when we have decentralised open source #DeltaChat from Europe?
I've published a temporary fork of Delta Chat for Android with UnifiedPush support: https://codeberg.org/s1m/delta-chaton
It will be automatically updated, as there should not be much conflicts between releases. I expect to discontinue this fork once (if) the support is merged
#deltachat @delta hello how difficult is to add an another theme for the app like this?
#DeltaChat getting some nice coverage in the media 👇🏻
The Best Private Messaging App Isn’t WhatsApp or Signal, It’s Delta Chat https://lifehacker.com/tech/delta-chat-messaging-app-privacy
one of the benefits of #hacking on an early project like #deltanet is being able to take a rattle-can and make your own graffiti
let's see if the author allows me to tag his building without a permit.
this is like the most exciting project i've experienced this year. bringing #fediverse like social web to #deltachat
if this pops off like i think it might, that whole fedi it's over trope may no longer be a trope

Messed around with an older Kindle Fire tablet this weekend, and stumbled-discovered you can side-load #fdroid through the Silk Browser. From there, you can install any of #deltachat, #ironfox, #orbot, #comaps,... even #supertuxcart
Installing apps through #AuroraStore is hit-or-miss, where the 'misses' are very informative: #firefox & #fennec must have hooks to Google Play Services, because they immediately crash upon opening in FireOS.

reflecting a lot on #fediverse lately. instance hopping is such an event and sometimes disruptive. ive spent a lot of time running #chatmail relays and until recently contributing to upstream. we can relay hop and its almost silent. your cryptographic identity is owned by you, not the relay operator. giving you a feeling or being nomadic. servers go down, operators retire or fade out. but you keep your identity.
this works great for #deltachat and enjoy the flexibility. but #activitypub doesn't have an agreed upon implementation. @silverpill is doing great work with his research and #mitra ecosystem. my hopes are eventually we'll see this on fedi across the ecosystems.
Surprisingly, got my whole family on #chatmail, #deltachat client precisely (while I use #arcanechat).
And it wasn't even me pushing for it, we needed to discuss something via secure channels, got them the choice between signal (secure but centralized) and DeltaChat (decentralized, "invite only", preferred by me) and they just switched.
It means that, between them and some of my colleagues, I have now switched my main messaging to Delta/Arcanechat.
I'll have to keep WhatsApp installed because it is used by some of my seldom contacted people (few colleagues, suppliers, etc), but back in the launcher drawer it goes!
Why the name #deltachat ? - here is my answer:
"delta" is often used to mean "difference," which felt fitting. not just in terms of making a difference, but also to find a place on scales like central-p2p or beginner-expert. if you think of a river delta, it’s also about things becoming broader and more distributed.
none of it fits 100%, i know :)
at the end, the name sounded nice to me, and i got a domain. also, i spent far too much time on naming and needed a decision :)

@delta Hmmz the volume of the microphone is really low when making a video call with #deltachat on iPhone. I can barely hear the other person, even when the volume is set to max.
Is this a known issue?

next #deltachat #ios version is coming with #liquidglass 🥛 thanks Amzd for the work. though frustrating being forced by #bigtech to do things that may not be loved and feel superfluous, it's wanted by many meanwhile.
there are still some things to tweak, we created an issue at https://github.com/deltachat/deltachat-ios/issues/3157 . on-point help is welcome - and already ongoing thanks to some new contributors ❤️
#Deltachat allows you to run applications within a given group/conversation. Today's application is arkanoid v. 3.10.0 by arcanecircle https://webxdc.org/apps/#arcanecircle-arkanoid Follow #webxdc for more apps.
@novarivera @bjornsdottirs our first pinned post here goes to a detailed description of (no) metadata in messages, including openpgp handling. The way #chatmail and #deltachat works and handles encryption and metadata-minimization is quite different from how email clients of the last ten years did it.
@STP_KITT We actually also got a lot of people being thankful that they could remove messages they had sent to the wrong chat, sometimes with sensitive info. See also https://www.typing.com/br/articles/making-digital-mistakes
As to editing one's own messages, we didn't hear many complaints although in theory it could be problematic. Mostly it's used for typo-fixing and fixing some grammatical nonsense, or some inline web-link. #deltachat is meant for usage with somewhat trusted people, not unknown people who try to trick you.
It's hard these days to find a unifying description, or know about all the people and communities involved in #deltachat #chatmail #webxdc developments. One shared sentiment probably is wanting to develop anti-authoritarian technologies and cultures around it, and being opposed to authoritarian tech policy moves in the West, chat control, age verification, prescribing Google/Apple control, enforcing digital app use etc
It's also a reason we are only posting on the fediverse bridged to bsky.
@delta what is this for a statement? "#deltachat is going proprietary with #chatmail relays"
As far as I can see the relay software is still licensed under MIT. Are there any changes planned, regarding this?
A note on "#deltachat is going proprietary with #chatmail relays":
1) It's all based on IETF standards, with configuration and custom integration code fully FOSS and documented at: https://chatmail.at/doc/relay/ with hundreds of permission-free deployments.
2) We know of several alternative relay implementations and deployments
3) Own servers or big email providers can be used (YMMV)
However it's fair to criticize our relentless focus on E2EE, and our moving away from email addresses as identity.
I'm officially one of you. Whenever I see graphics about digital sovereignty and moving away from Big Tech, I go: "well, actually" - especially when I see Signal suggested as an alternative to WhatsApp.
My first thought: Signal is pretty centralized, #DeltaChat would be a far superior alternative 🙈🙉🙊
Disclaimer: I use both (Signal and DeltaChat) but I really wish I could move all my convos to @Delta@chaos.social. Slowly convincing one person at a time...
What do you think is unique about the #deltachat project in the realm of secure cross-platform messaging?

That was easier than I thought it would be. 😀
Dear friends of the BSD Cafe,
One of the principles this place was built on has always been free communication. Whether on the Fediverse or on Matrix, the goal is the same: open, secure, private, decentralized tools. Because we know, from experience, that anything centralized will sooner or later come to an end.
Matrix is great, and we like it. But it's tied to its server - you can't migrate away (easily). It does its job well, yet sometimes it asks for more than a conversation should: heavy to host, hard to leave.
So when my friend @outofcreativity brought it up again at EuroBSDCon, I decided to give Delta Chat another try after many years. And yes - its philosophy fits mine, and the Cafe’s, well.
For a few months we ran a relay - a chatmail server - but it was on Debian, and I didn't want to make an official service that runs on Debian. Not because it doesn't work: it works perfectly. But because it wouldn't be in the spirit of this place.
Thanks to @feld 's excellent cookbook recipe, I also kept a private relay of my own running for months, just to test it. It held up beautifully. So yesterday, with the help of some friends in the cookbook chat, I migrated the Debian server to FreeBSD - accounts and data included - and I can finally call it a stable, official Cafe service.
Our chatmail relay - https://chatmail.bsd.cafe - runs on FreeBSD, in a jail. Which means it gets everything the other services get: hourly backups via zfs send and receive, FreeBSD's security, and all the rest.
I'd encourage everyone to try Delta Chat. Secure, decentralized communication built on protocols we already know and trust: the ones behind email. And the development is moving fast. Multi-relay is no longer a promise - it's here, and it's solid: a single profile can use several relays at once, so your account and your reachability survive even if one of them goes down and disappears. That's real resilience. The real decentralization, the one we love.
Because Signal is great. But Signal, too, is centralized. And we happen to like the true spirit of the Internet.

Did you know that ♪WhatsApp now his ♪AI read in all your chats if you don't disable it?
If you do not want to leave this AI to your private conversations for evaluation and training, you could finally change with good reason. (Or stop deactivating)
WhatsApp not only knows your messages - it knows your contacts, your communication routines, your groups. And all this ends up at Meta. Signal is the pragmatic way out: end-to-end encrypted, as little metadata as possible, no advertising model.
New in ♪UnplugBigTech Part 6: Set up signal, set the most important protection settings and start the transition without chaos. WhatsApp doesn't have to leave immediately - but signal will be your new standard.

This #deltachat is intriguing. I need to convince some of my contacts to try it with me.
we can't offer a full comparison but here are three key points:
1. Tox is not a cross-platform user offering like #deltachat, but more an infrastructure library like https://github.com/chatmail/core
2. Tox can only transfer messages between contacts who are online at the same time. complicates mobile usage.
3. Tox depends on a global distributed hash table (DHT) to find other contacts; doesn't work in highly restricted networks like during national internet shutdowns/larger failures etc.
Reminder: 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 federated e2ee-restricted SMTP network.
A chat profile or chat group has zero data on the server. It's radically different from classic email servers, Whatsapp, Signal, XMPP and Matrix servers which host and control chat identity.

Neo-spoon meme (scene from matrix movie where neo looks at a child bending a spoon which eventually tells him "there is no spoon") with the following words top: "On which server is your account?" and below the bending spoon "there is no account."
The tale of "convenience" is a bit of a trick. A lot of corporate provided services maybe were somewhat convenient a decade ago, but they are now increasingly authoritarian, and people tend to ignore how much time they steal.
Total number of hours spent solving captchas or consent screens with #deltachat #chatmail and #webxdc apps: 0 (zero). Nada. Zilch.
Compare with the estimated 819 million hours which humans spent with Google's recaptcha alone https://boingboing.net/2025/02/07/recaptcha-819-million-hours-of-wasted-human-time-and-billions-of-dollars-google-profit.html
#Conversations_im is currently in the Top 50 most download apps on @fdroidorg.
In the messaging category it ranks fairly close to #Element X and has almost 3x the downloads of #DeltaChat. Just to give you a perspective on loudness on social media vs reality.
While onboarding is extremely easy, the real challenge is to find initial contacts or circles to chat with. There is no discovery and no central registry. Every new chat profile is private and nobody knows about it other than your contacts. So we are curious. What is the current number of chats (1:1 or group chats or channels) you have with #deltachat apps? Not contacts but chats you have read or wrote something into, in the last months.

Good news among the bad news!
If the recent #0day attacks against Linux kernel+servers were launched against #chatmail relays, privacy of chatting with #deltachat is preserved. Why? Because we already assume the server could be actively hostile, and still not read or see any avatar, names or messages.
Since the March 2.48 zero-metadata releases relays/servers do not see cryptographic identities, and get no chance to launch "machine-in-the-middle" (MITM) attacks.
We 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 great firewall appears to block some #chatmail relays
- if you ask DeepSeek directly about Delta Chat, it doesn't want to talk
It's pretty sad, really. Everybody on this planet needs, and has a human right to private communication.

Making sure that deleted messages are actually deleted and unrecoverable is more involved than most folks think. The FBI could recently recover deleted Signal messages from an iOS phone because the notifications you see on your phone were stored in an extra database. Apple has now fixed this, also making #deltachat iOS users safer. Few know that so called "forward secrecy" is all about deleted messages becoming unrecoverable, see https://autocrypt2.org for our plans

#deltachat user profiles are private and invisible to the public. No one can discover you, or your children, via phone numbers or any other public handle. Chat profiles exist only on user devices. No PIN and no "SMS verification code" ever asked or needed.
The lack of "public discovery" also means you don't auto-discover others via phone numbers or other public handles. Getting in contact with others is "opt in": you scan a QR code or click an invite link to join a group or open a chat.
This morning nine.testrun.org was briefly unavailable, some network problem. A good time to remind everyone to add a second relay to your #deltachat app:
1. Go to https://chatmail.at/relays randomly choose one of the listed relay pages and copy the invitation code to your clipboard
2. In delta chat settings go to advanced/relays and tap "add relay" and paste the invitation code
3. That's it.
If one relay is unavailable you still can receive and send messages.

"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 communities that people are molding for themselves. We are just providing tools and approaches that work ... At least most of the time 😅 "Nothing works all the time" is another project mantra. Brb preparing the next releases :)

@pixelschubsi @adbenitez new protocols are fine. The point may rather be that contrary to popular nerd belief protocols are only one part of an effort. What distinguishes #deltachat from #xmpp is that one is a cross-platform mass-user focused app with a consistent UX across the platforms and using standards under the hood, while the other is a set of specs with many different implementations and UX approaches on the various platforms, and sometimes tenuous compatibility between them.
@rakoo no, user numbers are getting.increasingly unknown even to us. We tried to express this. That more people are joining the fun and contributing in various ways, is what we experience and appreciate. All three key efforts,#chatmail #deltachat and #webxdc are community efforts.
Just found out that Delta Chat doesn’t actually support voice or video calls… Yeah, sure, you can make calls by using a third-party app like Jitsi, BUT THAT HAS NOTHING TO DO WITH DELTA CHAT.
That’s how you ruin a simple app that even my grandma understood, turning it into something worthless and unusable for most ordinary people who don't have a clue. What a huge disappointment. #DeltaChat What a load of nonsense.
@delta
It’s a real pity because I loved Delta Chat for its simplicity. You could tell a non-geek: "Install it, choose a name, and let's start chatting"—it’s easy as shit. But the fact you can't make calls is a huge missing feature.
So, it’s time to look for another chat app that isn’t American and doesn’t lack essential features like calling. How the hell do you expect to compete with apps like WhatsApp and Signal if you're missing half the basics?
#deltachat contributors range from age 16 to 65, spanning diverse genders and even more countries and cultures. We have many discussions, and also conflicts but we usually don't carry those out in big public groups but rather go for 1:1s and generally small-group discussions. There is no central assembly or board that decides everything. It's more chaotic and admittedly hard to get an overview on, but thats' also how the yearly #CCC congress comes about, which many of us regularly attend.

@severin thanks! Unfortunately, it is not likely the apps will offer contact discovery themselves. It would bring #deltachat closer to being a social media app, and invite spam and abuse which we are not prepared to handle due to the decentralized nature of our efforts. We do not know, mediate or see any interactions between users, an providing central discovery would break that privacy property.
boostedAfter three intense months of work from more than a dozen contributors, #deltachat 2.48 releases are rolling. Maybe the most feature-packed releases ever?

- native Audio/Video calls on Android and iOS, as well as UbuntuTouch
- Group and Channel descriptions
- A new background audio player
- Revamped Download-on-Demand
and, last but not least, the long-awaited next-generation of messaging resiliency through "multi-path" routing ....
