How your data is handled

Signed-out birth details stay in this browser; after sign-in they sync to your US-hosted account. City searches and the coordinates/date-time needed for time-zone lookup go to Google Maps when the global provider is available. Raw birth details are not sent to AI; only derived chart facts are sent when you ask an AI feature. Privacy details
