Noonlight + Home Assistant

Hi all- I signed up for Noonlight and use Home Assistant. I entered my credit card info, but there really isn't an interface to manage my account or even cancel if I choose to. Am I missing something? I installed the Noonlight app and set a PIN in there, but it's unclear to me whether that is actually connected with my Home Assistant instance. In addition to that, it seems like the Noonlight integration for Home Assistant only uses coordinates, but that doesn't really work if you live in an apartment.

Maybe I'm missing something super dumb- so any guidance is GREATLY appreciated!
