Asterfolio Privacy Policy

Summary

Asterfolio does not collect data, track users, show ads, require an account, use subscriptions, or use a developer-operated backend. The developer does not sell or share personal information from the app.

Information Stored on Your Device

The app stores information you choose to enter, including observing sites, sessions, targets, user-entered sky conditions, telescopes, eyepieces, filters, magnification, notes, sketches or photos you select, and target queues. This information remains in local app storage on your device and is not transmitted to the developer.

Sharing and Exports

If you create a PDF packet, it is generated locally and passed to Apple's system share sheet. You choose the destination. The app does not upload the packet to the developer.

Permissions and Network Access

Version 1.0 does not request camera, microphone, location, contacts, photo library, or notification permission. It makes no developer network requests and contains no third-party advertising, analytics, tracking, or crash-reporting SDK.

Retention and Deletion

Local records remain on your device until you delete them or remove the app. Deleting the app removes local app data, subject to normal iOS backup behavior controlled by you and Apple.

Product Scope

Asterfolio is an observing notebook and optical calculator. It does not predict safe weather, navigation, solar-viewing safety, object visibility, or equipment suitability. Never view the Sun without purpose-built certified solar equipment and current expert guidance.
