Your birth date and name

The chart is calculated in your browser. The birth date and the optional name you enter are not sent to our server and are not stored by us. If you copy a share link, the date is part of that link, so anyone you send it to can see it.

Hosting and statistics

The site is hosted on Cloudflare. Like any web host, Cloudflare processes technical data such as your IP address to deliver pages and protect the site from abuse. We may use Cloudflare Web Analytics, which counts visits without cookies and without tracking you across sites.

Fonts

Fonts are loaded from Google Fonts. When your browser requests them, Google receives your IP address. See Google's privacy policy.

Advertising

The site does not show ads at the moment. If we add advertising (for example Google AdSense), we will update this page before the ads go live, including how advertising cookies work and how to opt out.

Children

This site is not directed at children under 13 and we do not knowingly collect their data.
