Privacy policy

Last updated October 26, 2026

This policy explains what information is collected when you use Exact Ruler at exactonlineruler.com (“the site”), how it is used, and the choices you have. If you have questions, contact us at hello@exactonlineruler.com.

The short version

Information stored on your device

To remember your calibration, preferred unit, ruler edges, grid setting and light or dark theme, the site saves a small amount of data in your browser’s local storage. This data stays on your device. It is not sent to us, and we cannot see it. You can delete it at any time by clearing this site’s data in your browser settings.

Measurements you take with the ruler are not recorded or sent anywhere.

Analytics

We use Google Analytics to understand how visitors use the site, such as which pages are viewed, how long visits last, the type of device and browser used, and the approximate region a visit comes from. Google Analytics uses cookies and similar technologies to collect this information. We use it in aggregate to improve the site and do not use it to identify you.

You can learn how Google uses this data at policies.google.com/technologies/partner-sites, and you can opt out with the Google Analytics opt-out browser add-on.

Advertising

The site shows ads provided by Google AdSense, which helps keep the ruler free.

If you are in the European Economic Area, the United Kingdom or Switzerland, you will be asked for your consent before cookies are used for personalized advertising, and you can change your choice at any time.

Fonts and hosting

The site loads its typeface from Google Fonts, which means your browser connects to Google’s servers and shares your IP address with them. Like most websites, our hosting provider may also keep standard server logs, such as IP addresses, browser type and the pages requested, for security and to keep the site running. These logs are kept only as long as needed for those purposes.

Children

The site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Your rights

Depending on where you live, you may have the right to access, correct or delete personal information about you, or to object to or limit how it is used. Because we don’t collect information that identifies you directly, most data relating to your visit is held by the services described above, and you can manage it through the links in this policy. For any request, contact us at hello@exactonlineruler.com.

Changes to this policy

We may update this policy from time to time. The date at the top shows when it was last changed.
