2019-02-11 Delta Chat

I think my favourite new chat app is going to be Delta Chat. It’s a chat client that uses your email account for everything.

Thus, you automatically get a robust back end for distribution.


  1. anybody who has an email address can be contacted (first message is unencrypted since the app needs to exchange keys, first)
  2. it’s decentralized (the infrastructure is not in the hands of Facebook, for example – which is what I don’t like about WhatsApp)
  3. you don’t have to hand over your phone number to anybody (that’s what I don’t like about Signal)
  4. perhaps chat is a bit slower, as messages travel at the speed of email, I don’t know? I don’t think I’ll mind, though.
  5. the imprint shows a German company being responsible for it all (which is only slightly better than Five Eyes)

Check out the FAQ. I need to read more about Autocrypt.

I’m not sure how they make money, however.



Very cool, Alex! Thanks for bringing it to my attention. If you’ve set it up already, did you set up a new (dedicated) email address to use with it? or just use your existing email?

Right now I don’t have enough friends to make it a necessity. Also, I kind of believe that Email is no longer that important, so I don’t mind my email app giving me an unread count at the same time that the chat app gives me the same unread count. In a way, the unread messages and the unread mails are the same, aren’t they? So I guess you could simply switch off notifications for one of the two. But for now, I made no changes whatsoever and simply think of it as “easier to use than them installing GPG and doing manual key management.”
