@GreyLinux I been using Signal since about 2018 (It might not be that year). Only with one person as another way of communicating but its been great.
I also have used Tox, Jami, Matrix, XMPP, Telegram, briar, delta chat, Session.
The ones I recommend are mostly Matrix, signal, xmpp (have not tested it much but its been good when I did) and DeltaChat (It uses email so as long as your email is private then it should be private to).
@GreyLinux If you want to try a fully decentralized chat messenger then Briar is nice to try.
DeltaChat is nothing more then a frontend for email but email can be really private if used correctly.
I made a video about session if you want to check it out
Its nothing different then any other messenger like Signal or Matrix and xmpp.
