Dont connect it to the internet. That’s all

Sounds like you’re discrediting our fellow user, u CIA?

I don’t know stremio but jellyfin (and Plex and emby) are interresting becquse they allow you to serve content outside of your local network.

A solution is that you manage the server and jellyfin and your friends/family connect to it. It only works if you have a decent upload or if you rent a server/vps

Delta chat implement some of those features.
