Your birth details stay on your device

Calculations run in your browser. We do not send entered birth dates, times, coordinates or chart results to an astrology service or our server. Inputs are not included in page URLs. There are no accounts or cloud-saved charts. Closing the tab clears the tool’s in-memory data; your browser may independently restore form fields or session history.

Site delivery and technical records

Cloudflare delivers the website and may process connection information such as IP address, request time, browser information and requested path for delivery, security and operational logs. These are separate from the birth information processed locally. This release includes no advertising, behavioral analytics or third-party tracking scripts. Fonts, city data and calculation libraries are hosted with the site.

Downloads and contact

Chart images are generated locally. Default exports exclude birth date, birth time and city, but planetary placements can still be personal. Review an image before sharing it. If you email us, your email provider and our mail provider handle that message; include only the information needed for your question.
