Privacy

Short version: this site does not collect personal data.

• Calculations run in your browser. The priority-date calculator works on a small data file that your browser downloads; the date and category you type are never sent to a server and are not stored (not even in local storage).
• No cookies. The site sets no cookies and uses no local storage.
• No third-party requests. Fonts, scripts, charts and data are all served from this site’s own domain. There are no ad networks, social widgets or trackers.
• Analytics: none at the moment. If we turn on a privacy-friendly, cookieless counter (Cloudflare Web Analytics), this page will say so first. No Google Analytics, no advertising or social trackers.
• Server logs. Like any web host, the hosting provider (Cloudflare) processes standard request data such as IP address and page URL to deliver the site and protect it from abuse. We do not receive or combine this with other data.
• Email. If you write to us, we use your message and address only to reply.
