Apart from the new #Gnome effort, there also is an interesting experiment of a #Rust terminal-client with #Ratatui -- for others to start from should they feel they need some enjoyable distraction :)

Here we go! The first release of my native Delta Chat client for GNOME is out! github.com/trufae/deltachat-gnome/r... cc @delta @gnome i'm using it in daily basis, and it's quite stable right now, but still lacks many features from the […]

the public #chatmail relay list https://chatmail.at/relay covers about ~20% or so of chat relays we heart about and have traces or hints from, and we definitely don't see everything -- which is how it should be :)

What if all public funding and all private donations to our efforts stop tomorrow?

Users should be fine for years thanks to the wonderful world-wide community of #chatmail relay operators 💜 Relays are dirt cheap to run. Also, our developments are much cheaper and less complex compared to what […]

Do you want to live in a world where private digital communication is not possible anymore? That's a growing reality for many people world-wide.

Private communication is extremely important to salvage into the digital realm and it's not just […]

#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 […]

Under the hood, we are using IETF Internet Messaging specifications commonly tagged as "email". Sounds old, right? Actually there is a lot of new stuff going on! For example, #chatmail apps now fully support:

- RFC9788 ("Header Protection") to achieve minimal metadata

- RFC9580 ("OpenPGP") to […]

@chiefbongo and no worries, contact discovery is more or less a no-go area, even though it is lightly discussed sometimes, but certainly not via a centralized server, let alone one that we would run.

@chiefbongo yes, calls are end-to-end encrypted. Sorry for not making this more explicit. We also still have work to do to update docs and get everything stabilized 😅

@jaseg in the very first sentence we try to clarify the scope, i.e. "With the latest 2.48+ releases, a chat message reveals close to zero metadata to servers." The key phrase here is "to servers", and we then detail all the data that was made invisible to the server.
If you want to discuss this […]

@jaseg yes, it's about message header metadata, and the fact that no cryptographic identities are visible on the transport layer, making it hard for hostile servers to track anything when users change relays. This blog post is not a security whitepaper, which we admittedly still need to update […]

After three intense months of work from more than a dozen contributors, #deltachat 2.48 releases are rolling. Maybe the most feature-packed releases ever?

- "zero metadata" messaging

- native Audio/Video calls on Android and iOS, as well as UbuntuTouch

- Group and Channel descriptions

- A […]

swiss news: a new chatmail relay https://chatsecure.ch ... hosted in denmark, however :) also there is an upocoming event in Môtiers in two days. And there was a podcast featuring delta chat last year […]

@ahalam all the mentioned metadata in the top post resides in the encrypted parts of messages. The server does not see group descriptions, names, avatars etc. We'll soon do a blog post on this and recent advances to "zero metadata" operations, stay tuned :)

screenshot of artifical WhatsApp screen courtesy of @fex@cfn.social [Lock Icon] Your personal messages are end-to-end encrypted¹ But: When you message someone is saved forever. When you type is saved forever. Your approximate location is saved forever. Every profile picture is saved forever. Every status update is saved forever. Every group name is saved forever. Every group description is saved forever. Every community name is saved forever. Every community description is saved forever. Every time you join a group is saved forever. Every time you leave a group is saved forever. Every new contact is saved forever. Deleting a contact is saved forever. What you search for is saved forever. Who you call and when is saved forever. When you hang up is saved forever. When you’re online is saved forever. When you’re offline is saved forever. Every link you open is stored forever. Your phone model is stored forever.

Your Wi-Fi network is stored forever. ..... Your IP addresses are stored forever. Your meta ID is stored forever. Your settings are stored forever. ¹Just in case your contacts don’t back up your messages with Google or Apple

End-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 […]

The 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. The tech demos and hacking results we presented to each other, were pretty mind blowing and tracing […]

Fun funding fact: If we had 10 times more money to develop #deltachat , the #chatmail relay network and the #webxdc secure mini app ecosystem, we would still have ten times less than what signal has (let alone Whatsapp or telegram). But we don't want to increase nudging people for donations, as […]

I know #Signal is very popular, but at least for me, using NVDA, the desktop client is far less screen reader friendly than the mobile clients. The mobile clients work far better for me, but I honestly don't use my phone for much these days outside of being a media player that can make phone […]

OH in some chaos circles "#deltachat is the new emacs of operating systems" ...
We are not sure about that 😂 but what we do know is we are soon bringing out releases that we have been working towards for 12 months in multiple already released steps. The funniest thing? Nothing changes on the […]

@liaizon @julien see https://delta.chat/en/help#remove-account -- if you delete your profile from your devices nobody will have the private key anymore. The addresses (if on a relay) are going to stop existing after some time. There is virtually no residue then.

@julien If you want to stop using Delta Chat you can just un-install it. If you are in group chats, it's nice for the others to leave group chats before deinstall.

Our strong focus on end to end encryption and zero metadata does mean that one of the original project notions of "you can use delta chat as a lightweight cleartext email client and your contacts don't need to care" was deprioritized since some time now and remains available rather for […]

some insights from #deltachat forum gardening 🌸

- we’re getting about 7 new feature proposals per week, with over 1k ideas shared so far

- we aim to keep things simple and focused, so we often have to say "no!", but:

- we do listen: over the years, we’ve fulfilled about ONE THIRD of your […]

Direct mention on groups User Story: I have created a group in Delta Chat and started to chat with some friends. I am able to say something like “@tom: you are right” so it is clear to what friend I am replying to, “tom” is the contact name I have set for my friend but other users see the name they have set for Tom, internally Delta Chat replace “@tom” with Tom’s email so this even work for people that don’t use DC or that don’t have Tom as a contact. Sometimes the group get a bit noisy, and I am somewhat busy, rather...

@tchambers you're not doing anything wrong ❤️ "@user", so called "mentions", are not implemented yet, but discussed at support.delta.chat/t/direct-mention-on-grou...

@pancake wasn't liquid glass only introduced last year from apple?

@pancake delta chat doesn't feel native on Android and iOS for you? Or do you mean desktop platforms?

@daniel We are currently in the process of removing three "legacy options" and it definitely costs us at least 100 times more effort that it took to introduce them.

#DeltaChat breaks the one app, one ID rule of phone-number-based apps by supporting multiple chat profiles. This allows for true private messaging where you can keep a public identity for the Web or Fediverse separate from a private one for family and friends. Managing multiple selves is a new […]

The total privacy of #DeltaChat has a trade-off: there is no global directory. Connecting for private messaging requires a direct QR scan or using an existing channel to exchange invite links. The hurdle is often the readiness of friends, family, or those around you to switch. However, once […]
