Mobile background notifications: the new service is in testing. It is not enabled in version 0.38, and server health does not confirm delivery to a phone. Release details.

Weather data itself (radar, warnings, forecasts) comes straight from NWS, SPC, NHC, RainViewer, and Open-Meteo — the app's Data Health panel (Data tab) shows those feeds live for your location. This page covers the parts frankweather.com hosts: the signed update channel and the self-hosted base map.
