Delta Chat (delta@chaos.social)'s status on Tuesday, 24-Mar-2026 20:21:17 JST Delta Chat

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. #Matrix stores similar scales of metadata on their servers, even if you can choose which server stores it.
Everything is better than #Telegram which additionally stores message contents in all group chats/channels and most 1:1 chats.

  @delta Wait. How does Delta protect metadata? I thought you had anonymous accounts but you can't protect metadata.

  @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 :)
