The short version
The calculators run in your browser. The dates you type are never sent to us, and this site doesn't use cookies.
What happens to the dates you enter
- Calculations: they happen on your device. We never receive the dates.
- “Remember my date on this device”: on the pages that offer it, ticking this box saves your date of birth in your browser's local storage, so the calculators can fill it in next time. It stays on your device. Untick the box, or clear this site's data in your browser, to delete it.
- Copy: puts the result text on your clipboard. Some results include the dates you entered, so you can paste them into your notes.
- Share: sends the result text you see and the page address. It doesn't add your date of birth, but keep in mind that an exact age, such as your age in days, can reveal it.
Cookies, analytics and ads
There are no cookies, no analytics and no ads on this site. If we add a privacy-friendly analytics tool or ads later, this page will be updated before they go live.
Server logs
Like any website, our hosting provider may keep standard server logs, such as IP address, browser type and the pages requested, to keep the site secure and running. These logs never contain the dates you type into a calculator.
