Privacy Policy
Calculations using the date of birth you enter run only in your browser. Your date of birth is never sent to our server or stored.
This site plans to show advertising from Google AdSense. Google and its partners may use cookies to show ads based on your visits to this and other sites. You can turn off personalized advertising in Google's My Ad Center.
We use Google Analytics to see which pages are read and to improve the site. It uses cookies to collect data such as pages viewed, device type and approximate region, without identifying you by name. The date of birth or name you enter is never sent. In Japan and many other regions, measurement starts as soon as a page opens. You can accept or decline in the notice shown on your first visit; if you decline, we stop measuring on this device and delete the analytics cookies already set. You can change your choice at any time with “Cookie settings” at the bottom of every page. For visitors from the European Economic Area (including the EU), the UK and Switzerland, no analytics cookies are used until they accept.
This site uses Google Fonts to display text. When you view a page, your browser loads font data from Google's servers, and information such as your IP address may be sent to Google. The date of birth you enter is never sent.
If you contact us by email, we use your name, email address and message only to reply, and we do not share them with third parties unless required by law.
