Your birth details stay in your browser

Your birth date, time and place

When you press Calculate, the calculation happens in your browser. Nothing you type into the form is sent to this site or anyone else.

The share link puts your details in the part of the address after the # sign. Browsers never send that part to a web server, so it does not appear in any server log. Anyone you send the link to can see the details in it, so share it only with people you are happy to tell.

Birth place search

To suggest towns as you type, your browser downloads a list of towns that start with the same two or three letters, from this site. Those requests show which letters were typed, not your birth date, time or the town you pick.

What our host sees

The site is served by Cloudflare. Like any web host, Cloudflare handles standard request information, such as your IP address, the page address (without anything after the #) and your browser type, to deliver pages and protect the site. We do not add tracking or analytics to that.

Photos

Some photos load from Unsplash’s image servers (images.unsplash.com), which receive the same standard request information when your browser fetches an image.

Changes

If we add anything that changes this, such as advertising, this page will say so before it goes live.
