Field notes
Location can be selected from city presets or entered as coordinates, and the page offers a separate control to use device location. It says calculations run in the browser rather than sending GPS coordinates to the server. Custom coordinates follow the device's time zone, so users working across time zones may need a city preset. Optional Google Analytics cookies can be rejected without affecting Moon tracking.
