Information We Collect

All calculators on this site run entirely in your browser. Values you enter into a calculator (loan amounts, dates of birth, health metrics, etc.) are not sent to our servers, stored, or shared — they exist only on your device for the duration of your visit.

We may use third-party services such as Google Analytics and Google AdSense to understand site usage and display advertising. These services may use cookies or similar technologies to collect information such as your IP address, browser type, and pages visited. You can control cookies through your browser settings.

Advertising

If this site displays third-party advertisements, the ad provider (e.g. Google AdSense) may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising through Google Ads Settings.

Children's Privacy

This site is not directed at children under 13, and we do not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
