Privacy Policy

Last updated: 2026-06-13

Overview

Online AR Ruler ("we", "our", "the app") respects your privacy. This policy explains what data is and is not collected when you use onlinearruler.pages.dev.

Camera Data

Your device camera is used solely to render the AR view and detect surfaces for measurement. Camera frames are processed in real time entirely on your device. No images, video frames, or camera data are ever transmitted to any server, stored locally beyond the current session, or shared with third parties.

Measurement Data

Measurements you take (lengths, areas, volumes) are displayed on screen only. They are not stored, uploaded, or associated with your identity in any way.

Analytics

We use Google Analytics to collect anonymised, aggregated data about page visits, device types, and geographic regions. This data does not identify individual users. You can opt out via your browser's analytics opt-out settings or by using an ad blocker.

Advertising

We use Google AdSense to display advertisements. Google may use cookies to serve ads based on prior visits to this or other websites. You can opt out of personalised advertising at google.com/settings/ads. Ads are only shown on non-AR content pages and a thin banner in the AR session. No ad network has access to your camera data.

Cookies

This site uses only third-party cookies from Google Analytics and Google AdSense. We do not set first-party cookies.

Children's Privacy

This site is not directed at children under 13. We do not knowingly collect any personal data from children.

Changes to This Policy

We may update this policy from time to time. The date at the top of this page reflects the most recent revision.
