Birth data and privacy
Understand why birth details are needed for a chart and how the platform separates sensitive profile data from unrelated product functions.
Why birth details are needed
A Human Design chart depends on birth date, local birth time, and birth location. Location is used to determine coordinates and the historical timezone rules needed for the calculation. The platform stores profile details in a consistent format so saved charts can be reproduced and checked later.
Treat birth data as sensitive
Birth details can be personally sensitive, especially when combined with names, locations, account identifiers, or relationship context. Birth profiles and resulting charts are therefore available only through the account that stores them and are covered by account-security, privacy-request, and deletion controls.
Not an advertising profile
Human Design Type, Authority, Profile, chart history, birth details, and related interpretations are not used to infer advertising interests. Advertising controls, if enabled, stay separate from your Human Design profile and follow your consent choices and any ad-free access on your account.
