Birth details stay local
Your birth date, birth time and the selected place are used in your browser to calculate your chart. The birth calculation is not sent to our server. If you enable “Remember on this device,” the form is stored in localStorage on that device; unticking it removes the saved copy. A shared computer can expose locally remembered details to other users.
Place search and technical requests
Searching for a city sends your search text to our server so we can query the GeoNames place database. Hosting and security systems receive ordinary request metadata such as IP address, URL and user agent. We do not deliberately add birth dates, times or selected-place coordinates to analytics events. City queries can appear in infrastructure request logs.
Optional sharing
Creating a share link sends only Sun, Moon, optional alternative Moon and Rising signs, plus a phase label. It does not send your birth date, time, location, email or name. Anyone with the link can view the result. Share records remain until removal or service maintenance; do not treat a public link as a private account. To request deletion, contact support with the link.
Analytics
We use self-hosted Plausible for aggregate usage measurement and events such as calculation completion or sharing. We configure no advertising cookies. We do not send your birth date, time or birthplace as analytics properties. Our hosting and DNS providers also process request data needed to serve and secure the site.
Security and retention
We limit access to production configuration and use HTTPS. Technical logs and backups are retained for operational needs and rotated; removal from active storage may precede expiration from backups. No system can promise absolute security. We do not sell birth information or operate accounts, payment processing or marketing-email subscriptions in this release.
Your choices and contact
Use the calculator without remembering inputs or sharing. Clear local site storage to remove remembered details. For data-access or deletion questions, write to [email protected]; include only the details needed to identify a request. We update this page if data practices change.
