PRIVACY / PLAIN ENGLISH
Your birth data is not social content.
Astrology.ac is designed to give you a useful chart before it asks you to create an account or save anything.
Anonymous chart calculations
When you create an anonymous chart, your name, birth date, birth time, birthplace, coordinates, and timezone are sent to our chart endpoint to perform the calculation. The endpoint returns the chart placements and does not write the birth inputs to a database.
Share links
A share link contains an authenticated-encrypted set of calculated placements and the display name you chose. It does not contain your birth date, birth time, birthplace, age, latitude, longitude, or timezone. Exact degrees remain encrypted; public receipts show sign-level results and categorical aspect evidence. Compatibility and current-weather views also use sign-level positions so repeated requests cannot reveal the sealed degrees. Anyone with the link can see the receipt, so use a nickname if that is what you want shared. Anonymous capability links expire after one year.
Place search
Birthplace suggestions are provided by Open-Meteo’s geocoding service. Your search text is sent to that service so it can return matching cities and timezones. Astrology.ac does not attach your name or birth date to a place-search request.
Analytics
We use Vercel Web Analytics and Speed Insights to understand basic usage and performance. Private chart and match tokens are replaced with generic route labels before analytics events leave your browser. We do not install advertising pixels, sell personal data, or build cross-site profiles.
Saved charts and compatibility
The first release does not persist saved charts or raw compatibility inputs. If optional accounts or saved charts are added, they will be opt-in and this page will be updated before those features launch.
