XuanSeal is a product team focused on deterministic BaZi charting and in-depth chart readings. We build tools that help people reflect on identity patterns, timing, priorities, and trade-offs.
- Deterministic Four Pillars chart generation from birth date, time, and location — free, with true solar time correction and the Li Chun year boundary.
- Paid readings built on that chart: Book of Fate (natal life reading), 2026 Fortune Book (annual timing), and Compatibility Book (pair reading), plus the XuanSeal Master annual membership with Daily Fortune and chart Q&A.
- Web-native reading pages saved to your account — read instantly online, yours to revisit anytime.
Your chart itself is computed by fixed calculation rules — the same input always produces the same chart. The reading prose is generated by a large language model working under structured BaZi prompts that are constrained to your chart's actual facts (Day Master, Five Elements balance, Ten Gods, luck pillars). If a reading misses, we regenerate it once for free and refund within 7 days if it still is not a fit.
- Cultural and entertainment use only: not medical, legal, psychological, or investment advice.
- Data minimization: we keep only the data needed to provide and secure the service.
- User control: deletion/export requests are supported via support@xuanseal.com.
- Product language and UX are reviewed before release for clarity and safety wording.
- We keep legal and methodology pages updated with major product changes.
- We monitor user feedback, failed flows, and quality regressions in weekly reviews.
