The ruler works entirely in your browser. Your calibration (pixels-per-inch), unit choice and theme are saved in your browser's local storage on your own device. This data is never sent to our servers, never shared, and you can delete it at any time by clearing site data in your browser.
Like most websites, our hosting provider may log standard technical data such as your IP address, browser type and pages visited, used for security and to keep the service running. We do not use this data to identify you.
We may show ads through Google AdSense. Google and its partners use cookies — including advertising cookies — to serve ads based on your prior visits to this and other sites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet.
You may opt out of personalised advertising by visiting Google Ads Settings. Alternatively, you can opt out of third-party vendors' use of cookies for personalised advertising by visiting aboutads.info/choices.
Our pages may link to external sites. We are not responsible for their privacy practices; please review their policies separately.
TrueRuler is not directed at children under 13, and we do not knowingly collect personal information from them.
We may update this policy from time to time. The "Last updated" date above shows the latest revision.
