Sidereal: Deep Sky Atlas Privacy Policy
Effective July 19, 2026. This policy explains how Sidereal handles information.
Summary
Sidereal does not collect data, track you, show ads, require an account, or use a developer-operated backend. The developer does not sell or share personal information from the app.
Information on Your Device
The app may store observing-site settings, favorites, plans, notes, and display preferences. These records remain in the app's local container and are not transmitted to the developer.
Device Permissions
Sharing and Exports
When you choose a share or export control, content is created locally and passed to an Apple system interface. You choose the destination. The developer does not receive the export.
Network Access and Third Parties
The app has no developer-operated account service, advertising SDK, analytics SDK, tracking SDK, or crash-reporting SDK. A clearly labeled external reference link may open a website only when you choose it; that website is governed by its own policy.
Retention and Deletion
Local information remains until you delete it with available controls or remove the app. Apple-managed device backups are controlled by your Apple settings.
Product Scope
Object positions and observing plans are educational aids and are not intended for navigation.
Children's Privacy
No personal information is knowingly collected from children or any other user because the app transmits no user data to the developer.
Changes
This policy and the App Store privacy disclosure will be updated before a future release changes these practices.
