Conflict of interest
Conflict-of-interest statement
2 min readWhere the money comes from, who has equity in what, and who, if anyone, gets to influence the methodology. The list is short because the situation is simple, and we want it to stay that way.
Funding
The site is funded by two paid downloads, both processed through Stripe: the $49 naming PDF and the 2026 forecast PDF. The chart calculator, compatibility tool, and learning content are free, no signup, no ads, permanently. The two PDFs are clearly marked, never blocking, and the chart you came for is always free.
Equity and outside positions
The team has no equity in any other BaZi venture, school, or commercial product. No one on the team holds a paid teaching position, course-platform contract, or advisory role with another BaZi business. If that ever changes, this page changes first.
Advertising and sponsorships
The site does not accept advertising, affiliate links, or sponsored content. There are no referral fees from book retailers, no rev-share with course platforms, and no paid placements in the bibliography or sources lists. References are listed because they are the references the engine uses, not because anyone paid to be there.
Methodology independence
Methodology decisions — which thresholds to use, which classical text to follow when schools disagree, which charts to ship as case studies — are not influenced by any external party. The thresholds are documented in docs/threshold-provenance.md with their reasoning; the lineage choices are documented at /learn/methodology. If a practitioner or institution wishes to argue for a different rule, the venue is a GitHub issue or a public methodology note, not a private arrangement.
Updates
This page will be updated if any of the above changes. Updates land in the public corrections log at /about/corrections, with the date and the nature of the change. The page is short on purpose, because change is meant to be visible.
