The calendar is made entirely in your browser. The schedule, dates and names you enter are kept in the page address so you can bookmark or share it; they are not sent to us or stored by us. If you share the link, whoever you send it to can see what's in it.
We may use Cloudflare Web Analytics, which does not use cookies, to count page views. Cloudflare processes standard request data (such as IP address) to deliver and protect the site.
We also record anonymous usage counts for each page view so we can improve the pages: the page path (never the names, dates or schedule in the address), the referring site or campaign tag, your country and device type, whether you used the generator, which buttons you pressed, how far you scrolled and how long the page was open. This uses no cookies and no identifiers that last beyond the page. Add ?notrack=1 to any page address to turn it off in your browser.
If we add advertising in future, this page will be updated before any advertising cookies are used.
Custody Days does calendar arithmetic only. It is general information, not legal advice, and it doesn't know your parenting plan or court order: where they differ, they apply.
