Privacy on this site

The synastry calculator runs entirely in your browser. Birth dates, times and time zones you type are used for the computation on your device and are never sent to us or anyone else. This site sets no cookies and runs no analytics.

The waitlist form collects your email address, your language, and the campaign tags in the link you arrived from (utm_source, utm_medium, utm_campaign, utm_content), plus a hashed copy of your IP address kept for one hour to limit abuse of the form. We use them to tell you when the app ships and to count which channels bring signups. Nothing else is collected. To be removed, reply to any email we send or write to the address on the App Store listing once it exists.

The Cosmea app, when it ships, keeps both birth charts in the phone's keychain and scores the calendar on the device. This site's privacy notice will be replaced by the app's full policy at launch.
