Privacy Policy

Your privacy matters. This policy explains how Online Ruler handles your information.

Information We Collect

Online Ruler runs entirely in your browser. We do not collect, store, or transmit personal data from the measuring tool. Your calibration values, unit preference, edge layout, and theme are stored only in your browser localStorage and never leave your device.

Analytics

We use Google Analytics to understand aggregate traffic such as page views and general location. This data does not identify you personally. You can opt out with browser extensions that block analytics scripts.

Cookies

We use minimal local storage to remember your calibration, language, and theme preferences. Google Analytics may set its own cookies. No advertising cookies are used.

Third-Party Services

We use Google Analytics for traffic analysis. When you submit the contact form, your message is processed by our API provider solely to deliver it to us. See Google's privacy policy at policies.google.com/privacy.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page.
