Frequently Asked Questions

AstroSanmei provides Sanmei-inspired personality analysis, character interpretations, similarity scores, relationship analysis, and fictional worldbuilding content. All content is provided for personal entertainment, reflection, and character exploration only.

The switch time shown on Home is the solar term transition time currently being applied. AstroSanmei changes the day pillar at the solar term transition time, not at midnight, so Today's Figure list may differ between morning and evening even on the same calendar date.

A 10.0/10 score means the year, month, and day pillars of the birth date all match. This full match occurs only about 24 to 26 times across 3000 years; at minimum, 60 years pass before the same set appears again, and in some cases it does not appear for 180 years. AstroSanmei handles solar term transition times through high-precision celestial mechanics calculations based on DE440/441, allowing a more precise comparison than a simple 60-day cycle or 12-part division of the year.

AstroSanmei uses NASA JPL's DE440 and DE441 ephemeris data, which provides high-precision planetary positions. This enables accurate calculations for anyone born between 601 BCE and 2400 CE.

No. All analysis is performed entirely on your device. The only network access is when you use the place name search feature, which uses Apple MapKit.

AstroSanmei is available for iOS. Please check the App Store listing for the minimum iOS version requirement.

Your profile, birth date, birth time, birth place, registered characters, and app settings are stored only on your device. If you enable the iCloud sync feature described below, registered character information can be shared across devices signed in with the same Apple ID. AstroSanmei does not send this information to a developer-operated server.

When you turn on iCloud sync in Settings, user characters on this device are saved to iCloud and merged with user characters from other iPhone/iPad devices where iCloud sync is also turned on with the same Apple ID. When you turn sync off, that device no longer participates in iCloud sync, and user characters are stored only on that device. Turning sync off does not delete user characters already saved on each device. Delete them on each device if needed. Your own profile information is not included in iCloud sync.

If you search for a birth place, place search and geocoding are handled by Apple’s MapKit. The text you enter may be processed by Apple in order to return place suggestions or coordinates. AstroSanmei does not receive or store your birth place search queries on a developer-operated server.

No. AstroSanmei does not require access to your current location for birth place input. You can search for your birth place manually by entering a town or city.

No. AstroSanmei is for personal entertainment, reflection, and character exploration only. Counselors, coaches, consultants, and other advisors may not use AstroSanmei for professional services, client reports, advice, or paid services.

No. AstroSanmei’s analysis results, similarity scores, relationship analysis, daily timing, and character interpretations are provided for entertainment and reflection. They are not medical, legal, financial, psychological, religious, career, relationship, or other professional advice. Do not rely solely on app results when making important decisions.
