Privacy

The application runs entirely in your browser. No personal data is sent to any server.

• Calculation: happens locally in the browser (NASA/JPL ephemerides).
• Storage: saved profiles, settings and templates live only locally (localStorage); a profile is saved only if you tick “Save”. Nothing is uploaded. You can back up / restore your data (export/import) or clear it in Settings.
• Place search: to turn a city name into coordinates it queries a public service (Open-Meteo); only the typed text is sent.
• The prompt is anonymous by default: your birth date, time and place are never included — only astronomical positions and aspects. The name is added only if you turn off anonymization yourself.

Passing data to an AI

When you copy or open the prompt in a third-party AI (ChatGPT, Claude, Gemini…), you pass data to that third party under its terms. We take no responsibility for that.

Analytics

The site shows no ads and stores no cookies. To see how many people visit, we use Cloudflare Web Analytics: it uses no cookies or localStorage, creates no visitor identifiers and does not store your IP address — only the country is derived from it. So we see aggregate page views and visits, where they came from, and the country and browser, nothing else. Analytics also cannot see your form data: your birth date, time and place are never sent anywhere, and everything is computed in your browser.
