Local calculation
Birth date and target date values are processed in your browser by JavaScript. The static site does not intentionally transmit those values to a backend service.
Privacy
Your birth date should not become a data point.
Age Calculator is built as a privacy-first static utility. The default build does not require login, uploads, analytics or active ads.
No account required
You can calculate exact age, birthday countdowns and milestones without registration, email capture or payment flow.
Advertising status
Reserved ad slots are inactive. No AdSense script, publisher identifier or ad request is included until explicitly configured later.
Future changes
If analytics or ads are added later, this page should be updated before deployment so users understand what changes.
