i am also in for any recommendation you can give me. how about a secure messenger like tox f.ex?
I've never used tox f.ex, nor do I know anyone else that has, so can't comment on it. I can however say that end to end encrypted messaging can now be engaged via using the Axolotl UT native Signal client https://open-store.io/app/textsecure.nanuc -
or by initiating a "secret chat" in Telegram using the recently updated TELEports client - https://open-store.io/app/teleports.ubports
There is also a (admittedly clunky) webapp for the Wire service as well - https://open-store.io/app/wireut.totalsonic
