I feel I'm potentially really bullish on AlbyHub, but I strugle to understand what it is exactly. For example I installed AlbyHub with Phoenixd on my Umbrel, but I'm not sure about who/where runs the Phoenixd node as I have nothing to backup out of a password for the app.

A bit confusing. I guess  I'm running a Phoenixd node alongside a LND node on my Umbrel Server, but I'm still not sure lol
