Privacy Policy

What we collect

The calculators run entirely in your browser. The numbers you type are never sent to our servers. We do not have accounts, forms that store data, or email lists.

Like most websites we collect standard server logs (IP address, browser type, pages requested, time of request) for security and to count visits. We use Google Analytics 4 to understand which pages are used. Google Analytics sets cookies and collects usage data under Google's privacy policy. IP addresses are anonymised by Google Analytics 4 by default.

Advertising and cookies

This site is funded by display advertising. We use Google AdSense and may use other third-party advertising vendors. These vendors, including Google, use cookies and similar technologies 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 to you based on your visit to this site and other sites on the internet. You can opt out of personalised advertising by visiting Google Ads Settings, or opt out of some third-party vendors' use of cookies at aboutads.info. Third-party vendors and ad networks serving ads on this site are listed in Google's ad technology providers page.

If you are in the European Economic Area, United Kingdom or Switzerland, you will be shown a consent message before advertising cookies are set, and you can change your choice at any time via the link in the site footer.

Third-party links

We link to marketplaces' own fee documentation. Those sites have their own privacy policies and we are not responsible for them.

Children

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

Your rights

Depending on where you live you may have the right to access, correct or delete personal data we hold about you. Since we do not collect personal data beyond standard logs and analytics, the practical route is to clear your cookies and use the opt-out links above. For anything else, contact us.
