If I use Umbrel and download Alby Hub on it, does Alby Hub run through TOR, or would it leak your I.P address?

or is it better to download Alby Hub on Windows and route it through a VPN? 

 Alby on Umbrel uses Umbrel's internal LND app for all the lightning-related management. It inherits LND's capabilities on your Umbrel's. NWC connections are done through Nostr.

 I guess if my Bitcoin/LND node is running on TOR, then Alby will also use TOR as well which is what you are saying I think. 

What is NWC? I never heard of it. 

 Yes, it should!

NWC is Nostr Wallet Connect - a protocol that you can use to give otehr apps or pepole permission to use your node. https://nwc.dev
