This policy explains what happens to data when you use calculator-free.com. It covers this website only, not any site we link to.
Every calculator on this site runs entirely in your browser. The numbers you type — your income, your weight, your loan, your dates — are never transmitted to us and are never stored anywhere. We do not run user accounts, we do not ask for your name or email to use a calculator, and we do not build profiles of individual visitors.
Three things on this site store or read data in your browser:
cft in your browser's local storage, so the site remembers whether
you chose light or dark mode. It never leaves your device and we cannot read
it.Google's use of advertising cookies is described in How Google uses information from sites or apps that use our services. A full list of the vendors Google may work with is at business.safety.google/adscookies.
Visitors in the European Economic Area, the United Kingdom and Switzerland are shown a consent message powered by Google's Funding Choices before personalised advertising cookies are set, as required by the GDPR and the ePrivacy Directive. You can withdraw or change that consent at any time using the privacy or consent link the message leaves on the page, or by clearing this site's cookies in your browser.
Independently of that message, you can:
Where the GDPR applies, advertising and analytics cookies are set on the basis of your consent; the theme preference is set on the basis of our legitimate interest in the site working as you left it. We hold no database of visitors, so there is nothing for us to retain or delete. Data collected by Google is retained under Google's own schedules, described in its privacy policy.
Under the GDPR you have the right to access, correct, erase, restrict and port your personal data, and to object to processing. Under the CCPA/CPRA, California residents have the right to know what is collected, to delete it, and to opt out of its "sale" or "sharing" — the opt-out links above are the way to exercise that here. Because we hold no personal data ourselves, a request about advertising or analytics data should go to Google; we will help you direct it if you contact us.
Pages load fonts from Google Fonts and the small country flags in the language switcher from flagcdn.com. Both receive your IP address as part of any ordinary web request. The site is served through Cloudflare, which processes requests to deliver pages and protect against abuse.
This site is not directed at children under 13 (under 16 in parts of the EEA), and we do not knowingly collect their data.
If this policy changes, the date at the top changes with it. Questions about privacy: contact us.
