ArcaneChat: Private chats for the family
ArcaneChat is a FLOSS private and secure messenger focused on privacy and friendly user experience.
๐ฌ Reliable instant messaging with multi-profile and multi-device support.
โก๏ธ Sign-up easily and anonymously, no phone number or any private data required.
๐ฎ Interactive mini-apps in chats for gaming, shopping lists, productivity and collaboration.
๐ End-to-end encrypted chats safe against network and server attacks.
ArcaneChat is a Delta Chat client and it is compatible with other Delta Chat clients.

As this is Deltachat, here is a privacy comparison with other messengers ( posted on [email protected] as well ) : https://eylenburg.github.io/im_comparison.htm
They are not totally the same tho, for example "Delete messages on device of recipients" says "no" for Delta Chat but it is already available in ArcaneChat (will come to DeltaChat "soon")
Also "Minimal metadata" says "no" while there is no personal data at all required to use ArcaneChat, accounts are fully anonymous hence what metadata and from whom?
so the table is getting outdated quickly ๐

Unfortunately email wasn never built for privacy. As DeltaChat and ArcaneChat both run on top of email, they suffer from many of the same privacy issues that have existed since the inception of email, over 50 years ago.
How is a picture stored that I send to a friend? Is it stored encrypted on the server or stored on the device?
What if I have two devices. In device 1 I received a picture. Now I want to see the picture on device 2, but my friend is offline. How will that work? Does it download the picture from device 1?
When you send ANY message (it doesn't matter if it is just text, image or other attachment) it is end-to-end encrypted and on the server it all looks the same, encrypted blobs, it is only visible in your devices.
If you have a single device the encrypted blobs are deleted immediately after downloading them, if tyou have more than one device, the blobs are stored up to 20 days in the server to give you the chance to sync your devices, if you use "disappearing messages" option or manually select and delete messages or use the "clear chat" option, then you have more fine control when it is removed.
About your friend being offline, the same rules apply, they will be able to download the images and other messages you send to them as soon as they come back online within 20 days :)
Of course, if you host your own server you can tweak it to your needs if the defaults of arcanechat.me don't suit you
Iโll have to wait for the iOS version, but I installed Delta Chat instead, to check it out!
