Session SimpleX Nextcloud Talk (self-hosted for family) 0xChat (Nostr) Keychat (Nostr)

Meet at a bar and do real life talk 😁 - or be a programmer.

Same problem. You'd need a foolproof disguise to get to the bar undetected, but you can only rent your disguise from the very same folks you're trying to hide from!

Signal the Protocol is good, & these are good adaptations of it. #SimpleX is what I recommend most typically among my circle. The basic idea of "2 relays, 1 per side, instead of one signal dot com for both sides of the chat" is a really easy no-cost privacy-win concept to communicate to technotypicals 🙂

Not sure on the details. 0xChat has written about it.
