Privacy Policy

Last updated: October 2026

What we collect

Every calculation runs in your browser. Birth dates and other values stay on your device and are not sent to our servers, unless you open a result link (see below). You do not need an account.

Result links

If you choose Copy result link on the chronological-age calculator, the link shows the birth date and calculation date. Anyone with the link can see those dates, and opening it sends the link to our hosting provider. Personal result links are kept out of search engines. For private dates, copy the age text instead of sharing a link.

Analytics

We may use privacy-friendly analytics to see overall use, such as page views and country. They do not use tracking cookies. An opened result link includes its dates, so only open one if you are happy for those dates to be in a link.

Cookies

We use only the cookies the site needs to work. We do not use tracking cookies or share data with anyone for advertising.

Who we share it with

We do not work with advertising networks. Our hosting, analytics and error monitoring providers may handle page requests, including the link of a result you open.

Changes

If we change this policy, we will post the new version on this page with a new date.
