Birth data
The calculator runs entirely in your web browser. The date, time, place and gender you enter are processed on your device and are not transmitted to us or to anyone else. If you use the share link, those details are placed in the part of the address after the “#” sign, which browsers do not send to web servers; anyone you send the link to can see them.
City list
When you start typing a birthplace, your browser downloads our static list of cities. The download is the same for everyone and does not include anything you typed.
Server logs
The site is served as static files by a content-delivery network, which, like any web server, processes technical data such as IP addresses and browser type in order to deliver pages and protect against abuse. We do not use these logs to identify visitors.
Cookies
The calculator itself needs no cookies. Our own pages do not set cookies for tracking. Our advertising partners set and read cookies and similar technologies, as described below.
Advertising (Google AdSense)
This site uses Google AdSense, a third-party advertising service, to show advertisements that help keep the site free. In connection with this:
- Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites.
- Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
- You may opt out of personalised advertising by visiting Google’s Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalised advertising at www.aboutads.info.
- How Google uses information from sites that use its services is explained at policies.google.com/technologies/partner-sites; its advertising cookie policy is at policies.google.com/technologies/ads.
- Visitors in the European Economic Area, the UK and Switzerland will be asked for consent through a Google-certified consent message before personalised ads are shown. Where required by law (for example in some US states), you can opt out of the “sale” or “sharing” of personal information for advertising.
Ad partners never receive the birth details you type into the calculator: those stay in your browser.
Analytics
We use aggregate traffic statistics (such as Google Search Console data about search impressions) to understand which pages are useful. We do not build profiles of individual visitors.
Children
The site is not directed at children under 13, and we do not knowingly collect personal information from them.
Changes
We will update this page, and its date, when our practices change.
