Musicolet

is it possible to use musicolet on a Rasperry Pi with remote access? or with automatic sycronisation? like I add something mp3 file on my phone and it automaticly sychonizes on the home server and vice versa? or ist jellyfin the only possible way for this. and FileBrowser? and how safe is it? portforwarding with noIP. is it possible to sperate the home network from the Home server network?
