Since delta Chat was born for increasing the privacy of the users , at least it seems me to understand:
- Independent of any company or services. You own your data.
- Your data are not saved on a central server; this way, in contrast to most other messengers, Delta Chat even protects your metadata (who writes to whom?)
- You do not distribute your address book to anyone.
whether not to prevent or to underline very well if the interlocutor uses email server as gmail, yahoo, amazon, hotmail, etc, etc?
just a warning like:
"attention your interlocutor is not using a server that respects your privacy!
Pay attention to what you write or attach!"
Or highlight in red the sender or recipient who uses these services.
