Privacy Policy

Last updated: July 2026

What we collect

Nothing you type into any calculator is collected. Salaries, allowances, loan amounts, and every other figure you enter are processed entirely in your browser and never leave your device. We do not require accounts and we do not store calculation history.

Preferences stored on your device

Your chosen color theme and light or dark mode are saved in your browser’s local storage so the site remembers them on your next visit. This data stays on your device and is not transmitted to us.

Advertising

This site displays ads served by Google AdSense to remain free to use. Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising in Google’s Ads Settings. For more on how Google uses data, see How Google uses information from sites that use its services.

Analytics

If we use analytics, it is limited to aggregate, non-identifying page statistics such as which calculators are visited. We do not link any analytics data to figures you enter, because those figures never reach us in the first place.

Your choices

You can clear your browser’s local storage at any time to remove saved preferences, and you can use ad-blocking or cookie controls in your browser. The calculators work the same either way.

Questions about this policy can be sent to the site owner through the contact details published on this domain.
