This privacy policy applies to the Pocket Ruler app (the "App") developed by Ho Pui Chung ("we", "us", or "our").
We do not collect, store, transmit, or share any personal data. The App has no account system, no analytics, and no network requests.
The Level feature reads your device's accelerometer sensor to measure tilt angles. All sensor data is processed entirely on-device and is never stored or transmitted.
The Ruler feature uses your device's screen size and PPI to render a physical ruler. No measurement data is recorded or sent anywhere.
The App does not integrate any third-party SDKs for advertising, analytics, or tracking.
The App does not knowingly collect any information from children under 13.
If this policy changes, the updated version will be posted at this URL with a revised "Last updated" date.
