Anonymous chats get their own store
Encrypted messages from anonymous chats are no longer kept in the main database.
When you turn a chat anonymous, your browser encrypts each message before it is sent. ZeroLog cannot read these messages. They are now stored apart from the main database, which holds your account and regular chats.
What you notice
Nothing, as long as it works. If the anonymous store is unavailable, an anonymous chat shows an error and saves nothing. It does not fall back to the main database. Try again a little later.
Deleting an anonymous chat, turning anonymous mode off, or deleting your account also deletes its encrypted messages. If they cannot be deleted at that moment, the chat or account stays and you see an error, so nothing is left behind unnoticed.
Regular chats are not affected. The anonymous chat guide explains how the encryption works.
