Night Astro Planner Privacy Policy

Privacy Policy for Night Astro Planner
Last Updated: November 8, 2026
Night Astro Planner ("the App"), developed by Jeremiah Pierucci, is designed with a strict privacy-first architecture. We do not collect personally identifiable information, do not track users across other apps or websites, and do not sell or monetize personal data.
This Privacy Policy explains how data is handled when you use Night Astro Planner.
Location Data
The App requests access to your device's location strictly to provide astronomical calculations and local observational planning:
• Astronomical Calculations: Real-time celestial coordinates, altitude/azimuth paths, moon phases, sunrise/sunset, and astronomical darkness calculations are performed on-device.
• Weather & Atmospheric Forecasts: To provide local cloud cover, transparency, seeing, and wind forecasts, geographic coordinates are transmitted securely over HTTPS to Apple WeatherKit in accordance with Apple's Privacy Policy.
• Light Pollution Maps: To display local Bortle class and artificial night sky brightness, the App requests map tiles from NOAA / CIRES Falchi 2016 World Atlas servers (hosted via ArcGIS) corresponding to your region.
• Interactive Maps: Site inspection and location selection utilize Apple Maps (MapKit).
Your location is never shared with advertising networks, telemetry brokers, or third-party marketers.
Astronomical Database Searches & Imagery
• Celestial Target Search: When searching for targets, queries are transmitted over HTTPS to scientific astronomical catalogs, including the CDS SIMBAD Astronomical Database, CDS Sesame, and the NASA/IPAC Extragalactic Database (NED). These requests contain only the queried celestial identifier and no user identifiers or personal data.
• Survey & Reference Imagery: Astronomical survey tiles and reference photographs are streamed on demand from public scientific repositories, including CDS hips2fits, the DESI Legacy Imaging Surveys, and Wikimedia Commons / ESO / NASA.
Data Storage & iCloud Synchronization
• No Account Required: You do not need to create an account or provide an email address to use Night Astro Planner.
• Private iCloud Sync: If you enable iCloud on your Apple device, your custom saved locations, saved target lists, equipment profiles, and imaging session logs are synchronized across your devices via Apple CloudKit. This data is stored exclusively in your private, encrypted Apple iCloud container. The developer has no access to your private iCloud data or database records.
In-App Purchases & Subscriptions
Subscription and in-app purchase transactions are processed directly by Apple through Apple StoreKit. The developer does not receive, process, or store your credit card information, bank details, or billing address. All billing records are handled according to Apple's standard privacy and payment terms.
Third-Party Analytics & Tracking
Night Astro Planner contains: • No third-party advertising frameworks. • No behavioral tracking tools or data brokers. • No cross-app tracking identifiers (IDFA).
The App's privacy manifest declares zero tracking and zero collected personal data types.
Data Retention & Your Rights (Data Deletion)
Because all your data is stored either locally on your device or in your private Apple iCloud container: • You can modify or delete your saved targets, locations, equipment profiles, and session logs at any time directly within the App. • You can purge cached forecast data at any time via in-app Settings. • Deleting the App and removing its data from your Apple ID iCloud Storage permanently removes your data.
Children's Privacy
Night Astro Planner does not knowingly collect or solicit personal information from children under the age of 13 (or under 16 in the European Union).
