There is no authentication enabled on meet.jit.si, but authentication is available for custom deployments of meet.jit.si without 2FA.
No history for a room is kept after the room is destroyed, which is when the last person leaves. So all messages are destroyed.
What do you mean?
Most of the active jitsi-meet maintainers are working for a company where we develop a video conferencing solution, meet.jit.si is a free service, which the developers use to improve with every new version and monitor in order to spot problems and add new features.
What do you want to know? meet.jit.si is currently deployed in 6 regions across the globe.
There are some analytics stored about usage, but they do not include ip addresses.
Meet.jit.si is using callstats.io for call statistics, where I think Ip address is stored, but they are GDPR compliant if this is what you are asking.
I’m not sure what metadata do you mean other the one explained above.
I’m not familiar with Wire and Signal, but Skype is a messaging app with option for video and videoconferencing. Meet.jit.si is not at all messaging app, doesn’t have accounts, you cannot send a personal message to a user … it is just adhoc meetings, with exchanging messages only inside meeting with no history.
I don’t see it in anyway categorized as messaging app/service where you need to be able to send messages to users, but you cannot as there are no user accounts
