where are the jitsi servers? Also how can I be sure that my data is safe? Finally, it’s meet.jit.si totally open source?
All the running software is opensource, there are few brandings on top.
If you do not trust it, you are free to deploy your own instance, all you need is a Debian/Ubuntu machine and a DNS pointed to it https://jitsi.org/qi.
ok thanks for the reply. And on a server, once a call is over, what remains?
sorry for my many questions, but how can we be sure of this?
Check the code, run it your self to verify or in case you don’t trust a my word, trust your deployment and use that. You are free to do so.
