Privacy Policy

Data we do not collect

The app does not collect, upload, sell, or share personal data that identifies you. It contains no third-party advertising or analytics SDKs.

• No account or sign-in is required
• No access to contacts, photos, camera, or microphone
• No request for or tracking of your precise location
• No cross-app or cross-website user profiling

Data stored on your device

Your building collection, reading history, cached full-archive entitlement, and previous-support marker are stored locally on your device. They enable collection and reading states and provide an offline entitlement hint. The developer cannot access these records.

Deleting the app will generally remove these local records. Device backup and restoration are managed by your Apple device and its system settings.

Maps and Apple services

The app uses Apple MapKit to display maps and StoreKit to process and restore in-app purchases. The app itself does not read your current location. Apple may process information needed to provide these system services under its own privacy policy; that processing is outside the app's control.

In-app purchases

Purchases are processed securely by Apple through the App Store. We do not receive or store payment card numbers, billing addresses, or other payment details. The app receives only the transaction status needed to verify an entitlement through StoreKit.

Children's privacy

The app does not collect personal data from children or knowingly collect personal information from anyone under the applicable age of digital consent.

Changes to this policy

If the app's features or data practices change, we will update this page and show a new effective date above. Material changes will also be communicated in the app or on the website when appropriate.
