Short version: the calculators run entirely in your browser, we don't ask you to sign up, and the main data collection here comes from advertising and analytics cookies.
Last updated: July 2026
We do not ask for or store your name, email or vehicle details unless you choose to send them through the contact form. Everything you type into the calculator and vehicle checker is processed in your browser and never transmitted to us.
This site displays advertising served by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the internet.
You may opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of a third-party vendor's use of cookies for personalised advertising by visiting www.aboutads.info.
We may use privacy-respecting analytics to understand which pages are useful and which are ignored. This measures aggregate patterns — page views, rough location at country level, device type — not individual identity.
You can block or delete cookies through your browser settings at any time. Blocking advertising cookies may make the ads you see less relevant, but the calculators will continue to work exactly as before, because they never depended on cookies.
Please do not send us vehicle registration numbers, chassis numbers, licence details or payment information. We have no use for them and no wish to store them.
This site is aimed at vehicle owners and is not directed at children under 13. We do not knowingly collect information from them.
If this policy changes, the updated date at the top of this page will change with it. Material changes will be noted on the home page.
