Birth dates in our tools
When you use a calculator, the date is processed in your browser and remembered only in your browser’s local storage so you don’t have to type it again. It is not sent to our servers.
Cookies, analytics and ads
To see which pages are helpful and keep improving the site, we use Google Analytics. It uses cookies to count visits in aggregate: pages viewed, approximate country, device and browser type. We do not use advertising cookies, we never sell data, and the birth dates you enter in our tools are not sent to Google Analytics.
Server logs
Like most websites, our hosting provider keeps short-lived technical logs (such as IP address and pages requested) to keep the site secure and running.
Your choices
- Clear your browser’s site data to remove a saved birth date.
- Use the site without entering any personal data — every article is readable without it.
- Block cookies in your browser or use Google’s opt-out add-on if you prefer not to be counted in visit statistics.
