Luban Craft Pro Privacy Policy

Last updated: 2026-07-23

Data Collection

This app does not require an account and does not use third-party advertising or tracking SDKs. Saved dimensions, recent calculations, and preferences remain on your device and are not collected by the developer.

Purchases

The Pro unlock is sold through Apple In-App Purchase. Apple processes purchase and payment information. The app reads App Store transaction entitlement only to unlock Pro features.

App-Specific Notes

• The app does not request location, camera, microphone, or contacts access.
• External resource links open only when you choose them; the destination website's privacy policy then applies.
• Ruler interpretations are cultural and design references and are not used for profiling or tracking.
