Your birth details and local storage

For calculation, birth date, time, location and settings are sent only to the this website’s calculation service. No model is called, no account is created and no database record is written.

Understanding and use

Unsaved details use this tab’s session storage to survive refresh and language changes. “Save on this device” writes browser local storage until you delete it or clear site data; others using the device may see it. Delete individual saved charts or clear all below. Downloaded files are your responsibility. The existing sign-in link carries no birth details. Public chart calculations are not saved to an account.
