Privacy Policy

What we do not collect

The values you type into any calculator on this site are processed entirely within your browser. They are not sent to us, not written to any database, and not visible to anyone but you. We do not operate user accounts and we do not ask for your name, email address or any other personal detail.

Local storage

Two preferences are saved in your browser's local storage: your chosen currency and whether you prefer light or dark mode. These stay on your device, are readable only by this site, and can be cleared at any time through your browser settings.

Advertising

This site is supported by advertising served through Google AdSense. Google and its partners may 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 based on your visit to this site and other sites on the internet.

You can opt out of personalised advertising by visiting Google's Ads Settings. You may also opt out of third-party vendors' use of cookies for personalised advertising through the Network Advertising Initiative opt-out page. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website.

Analytics

We may use privacy-respecting, aggregate analytics to understand which calculators are used, in a form that does not identify individual visitors and does not include anything you typed into a calculator.

Children

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

Changes

If this policy changes, the updated version will be posted here with a new date at the top.
