Privacy policy

The short version: our calculators run in your browser, and we don’t collect or sell the figures you type.

Information you enter into calculators

Every calculation on this site happens locally in your browser. The numbers you enter — prices, mileage, income and so on — are never transmitted to us or stored on a server. Your chosen currency is saved in your browser’s local storage purely so the tools remember it next time; you can clear it any time through your browser settings.

Analytics and logs

We may use privacy-respecting analytics and standard server logs to understand which pages are useful and to keep the site secure. This data is aggregated and is not used to identify you personally.

Cookies

We keep cookies to a minimum. We do not use them to build advertising profiles of you. Any third-party services (such as our content delivery network or advertising) may set their own cookies; you can control these in your browser.

Advertising

The site may display advertising to fund its free tools. Advertising partners do not receive any data you enter into our calculators.

Your choices

You can browse and use every calculator without providing any personal information. To remove the stored currency preference, clear your browser’s site data for this domain.
