This Privacy Policy explains what information MultiCalco (multicalco.com) collects, how it is used, and the choices you have. Last updated: July 16, 2026.
Information we collect
Our calculators run entirely in your browser, and we do not ask you to create an account. We do not collect the numbers you type into a calculator. We may collect standard, non-identifying technical data such as your browser type, device, and general location, and aggregated analytics about which pages are visited.
Cookies
We and our partners use cookies and similar technologies to run the site, understand traffic, and serve advertising. You can control or delete cookies through your browser settings; blocking some cookies may affect how parts of the site work.
Advertising and Google AdSense
We use third-party advertising, including Google AdSense, to help keep MultiCalco free. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google uses advertising cookies to serve ads based on your visits across the web.
You can opt out of personalised advertising by visiting Google Ads Settings at adssettings.google.com, or opt out of some third-party vendors at aboutads.info. Where required, we request consent for personalised advertising before it is served.
Analytics
We may use privacy-respecting analytics to understand which calculators are useful so we can improve them. This data is aggregated and is not used to identify individual visitors.
Links to other sites
Some pages link to external sites, such as source material for a formula. We are not responsible for the privacy practices of those sites, and we encourage you to read their policies.
Children
MultiCalco is a general-audience site and is not directed to children under 13. We do not knowingly collect personal information from children.
