Privacy Policy
Last updated: July 2026
Information We Collect
Age Calculator Online does not collect, store, or transmit any personal information. All age calculations are performed entirely in your web browser using client-side JavaScript. The date of birth you enter never leaves your device.
We do not require account creation, email registration, or any form of sign-up to use our free age calculator tools. Your privacy is built into the design of every calculator on this website.
How We Use Information
Since we do not collect any personal data, there is no information to use or process. Your age calculation data remains on your device and is deleted when you close the page or clear your browser data. We have no access to the dates you enter or the results displayed.
Cookies
We use minimal cookies for essential functionality, including:
- Theme preference — remembers your dark/light mode selection using localStorage (not a cookie, never sent to servers)
- Google AdSense — uses cookies to deliver relevant advertisements based on your browsing history
- Google Analytics — uses cookies to collect anonymized traffic statistics
You can control cookie settings through your browser preferences. Most browsers allow you to block or delete cookies from individual websites.

- Google AdSense — for displaying advertisements. Google may use cookies to serve personalized ads. See Google's Privacy Policy for more information.

Data Retention
We do not retain any personal data because we do not collect any. Anonymous analytics data (page views, browser type, approximate location) is retained by Google Analytics according to their data retention policies.
Your Rights
Depending on your jurisdiction, you may have rights regarding your personal data, including:
- The right to access any data held about you
- The right to request deletion of your data
