The daily check-in saves your birth date, mood, intentions and check-in date in browser local storage, along with saved stone selections. The birth-chart form can also save birth time, place, coordinates and a calculated chart. Google sign-in provides account information such as name, email and profile image.
Daily stone recommendations are computed in the browser from your saved inputs and sky context. The current forms save to this browser and do not automatically sync after sign-in. Authenticated profile and practice APIs can store submitted birth/chart data, check-ins and saved stones in Cloudflare D1; account and session records also use D1.
Local practice data is stored under chg-practice and remains until you clear this site’s browser data. Clearing browser data does not delete server-side account or profile records. The current interface has no account-data export or server-data deletion control; no automatic deletion period is specified here.
Cloudflare hosts the site and D1 storage; Google handles Google sign-in and authentication uses session cookies. If a birth city is not found in the local city table, the browser sends that city name to OpenStreetMap Nominatim. Full chart calculation loads Swiss Ephemeris code from jsDelivr. These requests also expose normal connection information to the receiving service.
