Privacy Policy

Last updated: 15 June 2026. This policy explains what data CalcBoxes collects and how it is used. In short: the calculators run in your browser and we don’t store what you type.

The calculations themselves are private

Every CalcBoxes tool runs entirely on your device using JavaScript. The numbers and dates you enter — your date of birth, weight, salary, loan details and so on — are processed locally in your browser and are never transmitted to or stored on our servers.

Information we collect

We use privacy-respecting analytics to understand which tools are popular and how the site performs. This may include your approximate location (country or region), device and browser type, and the pages you visit. This data is aggregated and is not used to personally identify you.

Cookies and advertising

CalcBoxes is supported by advertising, which may be served by Google AdSense and its partners. These third parties may use cookies and similar technologies to show and measure 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 to you based on your visit to CalcBoxes and/or other sites on the internet.
• You can opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalised advertising at aboutads.info.
• Where required (for example for visitors in the EEA, UK and Switzerland), we present a consent prompt before non-essential cookies are set.

How your information is used

We use the limited data we collect to operate and improve CalcBoxes, to measure traffic and tool usage, and to display advertising that keeps the site free. We do not sell your personal information.

Your choices and rights

You can control cookies through your browser settings and manage ad personalisation through the links above. Depending on where you live, you may have rights to access, correct or delete personal data held about you. To make a request, contact us at [email protected].

Children’s privacy

CalcBoxes is a general-audience site and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to this policy

We may update this policy from time to time. Any changes will be posted on this page with a new “last updated” date.
