Privacy Policy

Last updated: 13 July 2026

The short version

The calculators run entirely in your browser. The numbers you enter are never sent to our servers, never stored by us, and never shared. The only data practices to know about are the standard ones below.

What the calculators process

Amounts, rates and periods you type into a calculator are processed locally in your browser with JavaScript. If you use a "copy link" button, your inputs are encoded into the URL you copy — share such links only with people you want to see those numbers. Your theme preference (light/dark) is stored in your browser's local storage and never leaves your device.

Hosting and server logs

The site is hosted on GitHub Pages. Like virtually all web hosts, GitHub may log standard technical data (IP address, user agent, pages requested) for security and operations, governed by GitHub's privacy statement.

Advertising and cookies

If advertisements are shown on this site (for example via Google AdSense), the ad provider may use cookies or similar technologies to serve and measure ads, including personalised ads where you have consented. You can control personalised advertising through Google's Ads Settings, and manage consent through the banner where it appears. We do not run our own analytics cookies on the calculators.

Third-party links

Pages may link to external sites (official government resources, documentation). Their privacy practices are their own; this policy covers only calculatemoney.xyz.

Children

The site is a general-audience educational resource and does not knowingly collect personal information from anyone, including children.

Changes and contact

Material changes to this policy will be reflected on this page with an updated date. Questions? Contact us.
