Privacy Policy
Last updated: September 19, 2026
Your dates never leave your browser
Exact Age Calculator has no backend and no database. Every calculation — your date of birth, the reference date, and every result shown on screen — is computed entirely in JavaScript running in your own browser. Nothing you type into the calculator is ever sent to, or stored on, our servers.
What is stored, and where
The only information saved is two small preferences, stored locally on your own device using your browser's localStorage: your light/dark theme choice, and whether you'd like a site-link watermark included when you copy or share a result. Neither of these is personal information, and neither is ever transmitted anywhere — it stays on your device until you clear your browser data.
Cookies, trackers, and analytics
This site does not use cookies, third-party trackers, or analytics scripts, and does not run any advertising. There is no account system and nothing to sign up for.
Sharing a result
If you choose to copy a result or share it via WhatsApp or your device's share sheet, that action is initiated by you and sends only the text you can see on screen — we have no visibility into if or how you choose to share a result.
Changes to this policy
If this policy ever changes — for example, if a future feature needs to work differently — this page will be updated and the "last updated" date above will change accordingly.
