Privacy Policy

At Night Astro Planner, your privacy is foundational. We do not require accounts, do not collect personal information, do not use advertising SDKs, and do not track users across apps or websites.

Is my location data transmitted to remote servers?

We (the developer) never collect, store, or track your location on any server, and your data is never shared with advertising networks or data brokers.

• 100% On-Device Calculations: All astronomical algorithms, Julian date transforms, Meeus ephemeris equations, celestial trajectories, and 20-year historical sky climatology lookups are computed locally on your device.
• Apple Maps & Apple Weather (iOS): To display satellite maps, reverse-geocode place names, and fetch 7-day astronomical weather forecasts, your selected observation coordinates are transmitted directly to Apple via Apple MapKit, CoreLocation, and Apple WeatherKit in accordance with Apple's Privacy Policy. (On Android, interactive maps and weather forecasts use the Google Maps SDK and the MET Norway API).
• NASA GIBS Light Pollution Tiles: To compute high-resolution Bortle and SQM light pollution ratings and render the Dark Sky heatmap, the app requests regional satellite map tiles from NASA Earthdata GIBS (gibs.earthdata.nasa.gov). Only the regional map tile index is requested—never your personal identity.
• Private iCloud Sync: If you bookmark custom observing locations on iOS, they are stored on your device and synced exclusively to your personal Apple iCloud account via Apple CloudKit. We have no access to your iCloud data.

Zero Third-Party Advertising & Tracking

No advertising frameworks, data brokers, or cross-app tracking identifiers (IDFA / AAID) exist within the applications.
