Sibyl Compass is a free, bilingual, privacy-first metaphysics utility platform focused on transparent calculations, traditional-system methodology, and reflective interpretation.
This page explains who publishes Sibyl, how calculation and interpretation stay separate, which evidence labels appear in the product, and where the platform deliberately refuses false precision.
01
About Sibyl Compass
Four tools, one accountable product standard
Sibyl Compass brings Tarot, BaZi, Numerology, and Feng Shui into one bilingual learning and utility platform. Each system keeps its own vocabulary, rules, and limits rather than being collapsed into one generic spiritual score.
Free core access
The current core calculators, card library, profiles, guides, and method disclosures are available without an account or paywall.
Bilingual by design
English and Simplified Chinese pages are edited as complete local-language experiences, not displayed as duplicated bilingual bodies.
Utility before prediction
The product is designed to calculate, explain, and support reflection. It does not promise events, certainty, or guaranteed outcomes.
02
Methodology
Calculation first, interpretation second
A deterministic layer establishes the result before editorial content explains traditional terms or offers bounded reflection. Presentation components may display an engine result, but they cannot repair, infer, or replace it.
Named systems
Every result remains inside its named tradition: a Tarot draw is not a BaZi assessment, and personal Kua is not an Annual Flying Stars chart.
Visible conventions
Where a tradition has competing conventions, Sibyl names the selected method and keeps version information visible.
Fail closed
When time precision, civil-time ambiguity, unsupported interactions, or missing evidence could change a result, the product returns a review-required state instead of guessing.
Sibyl treats each calculation as a contract: defined inputs, a named rules version, structured output, explicit errors, and independent regression evidence for factual boundary cases.
Time is not one coordinate
BaZi and Kua distinguish local civil time, UTC instants, true-solar wall time, solar-term instants, DST ambiguity, and historical timezone provenance where those distinctions matter.
Expected results need independent evidence
Property tests can verify shape and invariants. Specific calendar, pillar, Kua, or Flying Star facts require a canonical specification or an external source rather than expected values generated by the same implementation.
Presentation does not calculate
Localized labels, charts, grids, and reports consume existing engine output. They do not recreate a flight order, pillar boundary, reduction trace, or derived metaphysics rule.
04
Editorial policy
Traditional vocabulary without manufactured certainty
Sibyl explains traditional systems in modern, readable language while keeping cultural interpretation distinct from scientific evidence and deterministic calculation.
Substance over filler
Editorial pages define the symbol or term, explain the named traditional frame, give practical reflection, identify limits, and link to the next useful concept.
No universal-consensus claim
A Founder-approved Sibyl convention is labelled as the platform's canonical specification. It is not presented as the only legitimate traditional lineage.
Review and correction
Content carries versions and provenance where useful. Material calculation or evidence errors are corrected through reviewed repository changes, tests, and release history.
05
Privacy and local-first principles
Personal inputs stay out of the public web
No account or email is required. Birth data, locations, Tarot questions, and private results are not placed in URLs, sent to analytics, or saved to cloud storage by default.
Local calculation
Current tools calculate in the browser whenever the approved architecture permits it. Place resolution uses a local dataset and does not bundle a birth date or time into a lookup request.
Explicit local storage
A feature such as the Tarot journal writes to local browser storage only after the user chooses to save. It remains deletable on that device.
Private results are not indexable
Private-result routes are excluded from the public sitemap and marked noindex/nofollow. Public learning pages never contain a visitor's personal inputs.
06
Limitations
What Sibyl does not claim
These tools present cultural, traditional, and reflective frameworks. They do not scientifically validate metaphysical systems and do not replace medical, legal, financial, safety, construction, or other professional advice.
No guaranteed outcome
A card, number, pillar, direction, or annual star does not guarantee an event, relationship result, health condition, or financial outcome.
Method differences remain real
Different schools may prioritize other rules, thresholds, chart orientations, or interpretive methods. Sibyl names its convention rather than hiding disagreement.
Precision has a boundary
Historical timezone data, provisional adapters, incomplete source precision, and near-boundary inputs are disclosed. Review-required states are a feature, not a missing prediction.
Evidence taxonomy
How Sibyl labels evidence
The evidence class tells you what a test or rule can prove. It does not turn a traditional system into scientific measurement.
PROPERTY
Property
Generated cases that test invariants such as valid ranges, stable shapes, uniqueness, or round trips without claiming a specific historical fact.
CANONICAL_SPEC
Canonical specification
A frozen Sibyl convention or traditional lookup table that has completed the required review and is tested independently from its implementation.
EXTERNAL_AUTHORITY
External authority
Evidence tied to a named outside source such as an astronomical publication or a specific IANA timezone database release.
