Data you enter
Dates of birth you enter into any calculator are processed entirely in your browser. They are not transmitted to our servers, not logged, and not stored anywhere. Close the tab and the data is gone.
Analytics and advertising
We may use third-party analytics and advertising services (such as Google AdSense) that collect standard technical information — pages visited, approximate location derived from IP address, browser type — to measure traffic and serve relevant ads. These services operate under their own privacy policies.
You can typically control ad personalization through your browser settings or the ad provider's opt-out tools.
Cookies
The calculators themselves set no cookies and use no local storage. Advertising and analytics partners may set cookies as described above; the site remains fully functional with cookies blocked.
Changes to this policy
If this policy changes, the updated version will be published on this page with a revised date. Continued use of the site after changes constitutes acceptance of the updated policy.
