Privacy policy

Last updated 2026-07-28.

Who is responsible

AlphaCalcs is an independently run website. The person responsible for this site acts as the data controller for the limited processing described below and can be reached at info@alphacalcs.com for any privacy question or request.

The short version

Numbers you type into a calculator never leave your device. We do not have accounts, and we do not sell personal data. Advertising and analytics partners do set cookies, and you can refuse them.

What we collect ourselves

  • Calculator inputs: nothing. All maths runs in your browser.
  • Usage statistics: pages viewed, approximate country, device type and referring site, through Google Analytics 4 with IP anonymisation.
  • Email: only if you write to us, and only kept as long as the conversation needs.

Advertising

Ads are served by Google AdSense and its partners. 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 to you based on your visit to our sites and/or other sites on the internet.

You can opt out of personalised advertising at Google Ads Settings, or opt out of third-party vendor cookies at aboutads.info. Visitors in the EEA and UK see a consent banner and no advertising or analytics cookies are set until a choice is made.

Legal basis (GDPR)

Consent for advertising and analytics cookies; legitimate interest for keeping the site secure and available. You can withdraw consent at any time by clearing site data or using the consent link in the footer.

Your rights

Under the GDPR you may request access to, correction of, deletion of, restriction of or portability of any personal data held about you, and you may object to processing. Write to info@alphacalcs.com. We do not sell personal information. You also have the right to lodge a complaint with your national data-protection authority; in the Netherlands this is the Autoriteit Persoonsgegevens.

Children

AlphaCalcs is not directed at children under 13 and we do not knowingly collect their data.
