Privacy policy for StarHop Navigator.
StarHop Navigator is an offline app. Your data stays on your device — with one exception: the weather query via Apple WeatherKit (see below).
The app uses the accelerometer, compass, and your location to calculate astronomical positions. This data is processed exclusively on your device.
Your location is used for three purposes:
Sky calculations — Azimuth and altitude of stars and deep-sky objects depend on your location. This calculation happens locally on your device.
Weather data — When creating an observation session, your GPS coordinates are sent to Apple Weather (WeatherKit) to fetch current weather conditions (temperature, wind, cloud cover, humidity). This happens automatically when a session is created and can be repeated manually via the “Fetch Weather” button. Weather data is stored locally on your device. More information: weatherkit.apple.com/legal-attribution
Observation site — Your location is reverse-geocoded into a place name that is stored in the observation session. This query uses Apple services.
Settings, favorites, equipment data, and observation notes are stored locally on your device.
