Privacy Policy

About this policy

This policy describes the current operation of Precise Online Ruler at preciseonlineruler.com. It covers the ruler and the information pages on this website.

Measurements stay in your browser

The ruler calculates measurements on your device. The current tool does not upload your selections or measurement history to a measurement server. Your five most recent drag measurements are held in memory and are cleared when you reload or close the page.

Settings saved on your device

When browser storage is available, the ruler uses local storage to remember calibration and preferences between visits. These settings include the scale, calibration method, display characteristics used to check that scale, units, ruler edges, crosshair preference, selected device model, and custom reference length.

This information is stored in your browser, without an account. Local storage is different from a cookie and is not automatically sent with page requests. You can remove saved settings by clearing this website’s site data in your browser. If storage is unavailable, settings apply only to the current visit.

Cookies, analytics, and external resources

The current site code does not set advertising or analytics cookies or include third-party analytics or advertising scripts. Fonts are served with the site.

Website delivery

To deliver a webpage, the hosting infrastructure receives technical request information such as an IP address, requested URL, and browser request headers. The hosting provider may process access or error logs for delivery, security, and troubleshooting. These requests are separate from the measurements calculated locally by the ruler.

If you contact us, you choose what to share. A message may include your email address, its contents, and any attachments. We use that information to respond to your request and investigate issues.

You can use the ruler without an account, clear saved site data through your browser, and choose whether to contact us. To ask about personal information you have shared or request its deletion, use the details on our Contact Us page. Available privacy rights depend on your location and applicable law.
