Privacy Policy

Last updated: April 2026

      CrownSide does not collect, store, or share any personal data. No account is required, and the app works fully offline.
    

Data Storage

All data you enter into CrownSide — including watch details, wear records, measurements, and maintenance history — is stored locally on your device using Apple's SwiftData framework.

If you have iCloud enabled on your device, your data may sync across your own Apple devices via iCloud. This sync happens entirely within your Apple account and is not accessible to us.

No personal information
No usage analytics or telemetry
No crash reports sent to third parties
No advertising identifiers
No location data

Third-Party Services

CrownSide does not integrate with any third-party analytics, advertising, or data platforms. No data is shared with or sold to any third party.

Export

CrownSide allows you to export your watch data as a JSON file. This export is initiated solely by you and is not transmitted anywhere automatically. You control where it goes.

Children's Privacy

CrownSide does not knowingly collect any information from anyone, including children under 13.

Changes to This Policy

If this policy changes, the updated version will be posted on this page with a revised date. Because we collect no data, changes are unlikely to affect you.
