Privacy Policy — AR Ruler
Effective July 14, 2026 · Ad-free utility, developed and maintained independently.
What the App Does
AR Ruler lets you measure distances, angles, and areas using your device's camera and ARCore, and includes a bubble level and a compass. All measurement, level, and compass functionality runs entirely on your device.
Camera Access
The app requests camera permission solely to power the live AR preview used for real-time measurements via Google's ARCore. Camera frames are processed on-device, in real time, to detect surfaces and track the phone's position. No camera image, video, or frame is ever saved, stored, or transmitted anywhere — nothing leaves your device.
Data Collection
AR Ruler does not collect, store, or transmit any personal data. No account or sign-in is required or offered. No analytics, tracking, or advertising SDKs are included in the app. No network requests are made by the app at all — it has no internet permission and does not need one. Measurement results (points, lengths, shapes) exist only in memory while you use the app and are not saved to disk or sent anywhere.
Local Diagnostic Log
The app keeps a small, on-device diagnostic log of basic in-app events (such as which screen was opened) to help with troubleshooting, automatically discarding anything older than 24 hours. This log is stored only locally on your device and is never sent automatically anywhere — it is only ever shared if you explicitly tap the "Log" button and choose an app (e.g. email) from the system share sheet to send it, entirely under your control. If you choose to use the "Log" feature, your device model, Android version, and app usage logs will be attached to an email that you send yourself from your own mail app to the developer. This is entirely optional and initiated by you — the app does not transmit this data automatically.
Third Parties
The app does not share any data with third parties, because it does not collect or transmit any data in the first place.
Children's Privacy
The app does not knowingly collect any information from anyone, including children, since it does not collect information at all.
Changes to This Policy
If this policy ever changes — for example, if a future version of the app adds new functionality that touches user data — this document will be updated accordingly.
