Privacy

The short version: what you type into a calculator stays on your device.

Birth data

Names, birth dates, times and places are processed by code running in your browser. They are not sent to our server or to anyone else. The place search downloads a small list of cities that start with the first two letters you type, and filters it on your device; the server only sees which two-letter list was requested, the same file for everyone.

Share links keep your details after the # sign in the address. Browsers never send that part of an address to a server, so a shared link carries the data to the person you send it to, and to nobody else. Anyone with the link can see the details in it.

Stored on your device

Nothing, unless you tick "Remember on this device". Then your last form entries are saved in your browser's local storage so the form fills itself next time. Untick it and they are deleted. Your light or dark theme choice is also remembered locally.

Visit counter

We count page views with our own cookieless counter. It records the page path (never the part after #, never anything you typed), the referring site, a country code from our network provider, a rough device type, browser and operating system. Visitors are told apart by a daily hash that cannot be linked across days or traced back to an IP address. There are no cookies, no ads and no third-party trackers.
