Privacy Policy

Introduction & Privacy Principles

At UltimateOnlineRuler.com, we believe that simple web utilities should respect your privacy. This Privacy Policy explains how information is handled when you visit our website.

Because our measurement tools run entirely in your web browser, we do not collect, process, or store your measurements, coordinates, or camera feeds on our servers.

Client-Side Measurement & Local Storage

All calculations—including line distances, circle dimensions, rectangle measurements, and angle calculations—are executed entirely within your browser runtime.

We use standard browser localStorage exclusively for your convenience:

• Display Calibration: Saves your calibrated pixels-per-millimeter ratio so your physical scale calibration is preserved across visits without needing to recalibrate every time.
• Unit Preference: Remembers your preferred measurement unit (cm, mm, inch) for the home route.

Web Analytics & Server Logs

To ensure reliability and monitor aggregate website performance, we may use Google Analytics. Google Analytics collects anonymized, aggregate telemetry such as page views, general device category (desktop/mobile), country of origin, and referral sources in accordance with Google’s privacy policy.

Our web hosting infrastructure may record standard web server access logs (such as IP address, request timestamp, HTTP status, and user-agent) strictly for security monitoring, DDoS prevention, and routing.

Third-Party Services & Advertisements

We may display contextual advertisements through Google AdSense or affiliate partner links to support the free operation of this tool. These third-party networks may use cookies or web beacons to serve relevant advertisements based on visits to this and other websites.

You can manage or disable cookies at any time through your browser settings or opt out of personalized advertising via Google Ad Settings.

Children’s Privacy

UltimateOnlineRuler.com is a general audience measurement utility and does not knowingly collect any personal information from children under the age of 13.
