Information We Collect
Your Birth Date can be used without creating an account, and we do not collect personal identifiers such as your name or email address. Your birth date is processed in the browser for the life-grid calculation and is not sent to or stored on our servers. We aggregate only anonymous usage statistics such as visits and shares.
Browser Storage
Your birth date is stored only in your browser's localStorage so you do not have to enter it again. It remains on your device and is used only to calculate your life grid.
Advertising Cookies
We may show ads through Google AdSense to support the service. Google and other advertising partners may use cookies to serve ads, and you can manage your ad personalization preferences on Google's Ads Settings page.

If you have any questions about how we handle information, please reach out to the site operator.
