It packetises and encrypts chats, using email(SMTP) as the transport medium.
Sends downsampled pics, videos or push-to-talk audio by default. Can send full quality pics, videos, or attachments too, as a file.
Integrates with Jitsi Meet to connect video-calls.
It’s available on F-Droid, and you can use a seperate free-email-address(100MB limit) for the SMTP backend (from https://nine.testrun.org/ ), or use your own existing email address.
Do note, because it’s using email, the recipient and sender are not private, along with the time, and probably the relative size of the messages.
The specific content of each message should be private as long as the encryption is done well. I haven’t looked at it so I don’t know if it implemnts safeguards to verify who you’re messaging with (besides using the email address) and I don’t know if it uses PFS (Perfect Forward Secrecy) to protect against a key getting compromised.

Elegant and robust.

No spam, because it is a family group for sharing non-public pictures etc.
You’d only get spam if you invited a spammer to chat.
The privacy comes from the E2EE.

I haven’t used Signal.
Is your ‘registered Signal number’ your phone handset number?

[You are right, Delta Chat uses AutoCrypt, which is OpenPGP based.]

I mainly want personal family photos away from long corporate data retention (and possible leaks) and away from AI scrapers.
Delta Chat covers this.
I’ll check out Signal again though, thanks for the recommendation.

Really cool! An interesting concept well executed. Sadly has the same problem every new messenger has - barely any users.
But that’s hardly their fault.
