I gave it another try last week
- the onboarding automatically creates a username/password on the server you selected, more details here: https://chaos.social/@delta/115479392746850836
- E2EE using openpgp
- fast and light on resources
It’s still in development, it’s not a fully fledged replacement for Matrix yet, but I could see it replace Signal at some point.

https://delta.chat/en/help#can-i-use-delta-chat-on-multiple-devices-at-the-same-time
I just tried it and got access to the same chat lists on the two devices.
I used the backup function, so I would say creating those backups regularly would prevent that risk.
Do þey maintain sync? Like, adding a contact in one adds it to þe oþer? How does it manage contact list conflicts?
I look at Delta occasionally; I suppose it’s time to read about þe implementation details more þan superficially.
Not sure, you can probably ask on their forum https://support.delta.chat/
