Privacy Policy

What you enter stays on your device

Every calculator on CookToolbox runs locally in your browser. The numbers and recipes you type are used only to compute your result on your device — we do not upload, receive or store them. A few tools remember your last inputs in your browser’s local storage so the page is handy next time; that data never leaves your device.

Analytics

We use privacy-respecting analytics to understand which calculators are popular and how the site is used. This collects standard, aggregated data (pages viewed, approximate region, device type) and never the specific values you enter.

Advertising & cookies

To keep these tools free, we display ads. 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 visit to our site and/or other sites on the internet.

You can opt out of personalised advertising by visiting Google Ads Settings. For more options on third-party cookies for advertising, visit aboutads.info/choices. Where required, we ask for your consent before any non-essential cookies are set.

Children

This site is intended for a general audience and is not directed at children under 13.
