Privacy Policy

Last updated: August 2026

Who we are

CarRunningCosts (carrunningcosts.co.uk) is a small, independently run website providing free car running-cost calculators. This policy explains what happens to your data when you use the site. If you have any questions, contact hello@carrunningcosts.co.uk.

The calculators themselves

Every calculator on this site runs entirely in your own browser. The distances, fuel prices, and other figures you type in are used only to work out the result shown on screen — they are never sent to, processed by, or stored on our servers. If you close the tab, that information is gone.

Cookies and similar technologies

This site itself does not set any cookies of its own. However, if it displays advertising or uses analytics (see below), those third-party services may set cookies or use similar technologies in your browser to remember your visit, measure site usage, or show relevant ads.

Advertising

This site displays, or intends to display, advertising served by Google AdSense. Google and its advertising partners may use cookies and similar technologies to serve ads based on your prior visits to this and other websites, and to measure ad performance. You can learn more about how Google uses this data at Google's Partner Sites policy, and you can opt out of personalised advertising at any time via Google's Ads Settings or aboutads.info.

Analytics

We may use privacy-focused analytics tools to understand, in aggregate, how many people visit the site and which calculators they use, so we can improve them. Where analytics cookies are used, they do not identify you personally.

Children's privacy

This site is not directed at children, and we do not knowingly collect personal information from anyone under 13.

Your choices

You can control or delete cookies through your browser settings at any time. Blocking cookies may affect how ads are shown but will not affect how the calculators work, since they don't rely on cookies to function.

Changes to this policy

If this policy changes — for example, when advertising or analytics services are added — we'll update this page and revise the "Last updated" date above.
