Mystic Universe collects the following information to provide our services:
▸ Guest Saju Analysis
▸ Social Login Members (Kakao / Google)
Note: For guest analyses, only anonymous, non-identifiable statistical data is stored on our servers:
Birth year, gender, country code; Saju day pillar, zodiac, shinsal (values derived from birth data); blood type & personality type (if entered); AI tier, language setting.
Name, phone number, exact birth date, birth time, and city name are never stored on the server.
Note: No separate registration form — membership is via social login only. When members save a Saju to their vault, the full birth date (year, month, day), birth time, and city are stored. This information is used to calculate Daeun (Major Fortune Cycles) and Seun (Annual Fortune) cycles, and is permanently deleted upon account withdrawal.
