ChartOdyssey is designed so the core generator does not need an account, database, upload, or calculation API.
Minimal analytics
If analytics is enabled, events may record page, generator success, style, download, copy, or share actions. They must never include raw birth inputs or coordinates.
Your controls
You can clear a result by refreshing the page without its sign-only query string. ChartOdyssey does not create a cloud history.
Analytics preference
Allow anonymous GA4 page views and the fixed interaction events described above. Birth date, time, city, timezone, coordinates, and URL query parameters are never included.
Google Analytics is disabled on this device.
