1. Overview and Service Scope
HexaSage (hexsage.ai) is an I Ching strategic sandbox system rooted in the 3,000-year Book of Changes (Zhouyi) symbolic-logic framework, modern celestial mechanics (true solar time, high-precision solar longitude algorithm), and natural language processing. Generative AI serves strictly as a digital semantic translator and literature interface; the systemic methodology rests entirely upon classical I Ching treatises. The platform is strictly designed as an intellectual decision-support heuristics tool and cultural research instrument. We unequivocally repudiate superstition and do NOT provide any psychic, fortune-telling, divination, or supernatural outcome predictions.
This policy outlines how we adhere to legality, fairness, necessity, and data minimization when collecting, processing, and protecting your data.
2. Information We Collect (Data Minimization & Physical Coordinates)
Account Information: email address, nickname, gender, and country/region, utilized solely to authenticate and administer your SaaS account.
[Physical Coordinates Nature of Birthdates]: Birthdates entered under Earthly Branch Archetypes or Solar-Term Ephemeris are processed strictly as astronomical coordinate timestamps for celestial mechanics algorithms (Equation of Time, solar longitude term boundaries). This data is never linked to legal personal identities, government IDs, or sensitive PII, and is never monetized or shared with third-party advertisers.
Research & Deduction Data: user-submitted inquiries, generated hexagram matrices, classical literature cross-references, credit consumption logs, and study streak histories, processed solely to render deductions and refine platform capabilities.
Payment Credentials: order tokens, package tiers, transaction amounts, and status. Sensitive financial credentials (credit cards, CVV) are processed exclusively by certified PCI-DSS compliant gateways (such as PayPal); our servers never store raw payment data.
Technical & Security Logs: IP addresses, browser specifications, and security audit logs, collected strictly for infrastructure resilience and abuse prevention.
3. Data Usage, Zero-Training Commitment & Cognitive Privacy
We process collected data exclusively to maintain cloud services, execute astrometric calculations, process billing, and deliver customer support.
[Zero-Training Commitment & Cognitive Privacy]: We recognize that a leader’s inquiries reflect deep personal strategic deliberation. We strictly commit that your submitted strategic queries, astronomical birth data, and AI-synthesized deduction reports will NEVER be utilized to pre-train, fine-tune, or populate any public Large Language Models (LLMs) or third-party artificial intelligence foundation models. All AI inference is executed via stateless, end-to-end encrypted pipelines, ensuring zero cognitive residue and safeguarding your cognitive privacy.
4. Information Sharing & Third-Party Disclosure
We never sell, rent, or monetize your personal information to third parties. Data exchange occurs strictly within necessary operational boundaries: (1) Payment Processors: securely exchanging transaction tokens with licensed processors (PayPal) to complete purchases; (2) Algorithmic Model Providers: transmitting anonymized symbolic hexagram structures to dedicated AI models for semantic synthesis under strict non-retention agreements; (3) Statutory Obligations: disclosing data solely when compulsory under valid statutory law, court subpoenas, or binding governmental enforcement.
5. Data Security and Global Storage
We maintain enterprise-grade security infrastructure. All data in transit is encrypted via TLS 1.3 / HTTPS protocols, and stored data is protected with AES-256 encryption at rest. Cloud servers reside in high-tier data centers equipped with automated firewalls, intrusion detection, and access controls to prevent unauthorized access or disclosure.
6. User Rights & Right to Erasure (GDPR / CCPA)
You maintain comprehensive statutory rights over your personal data, including the right to inspect, export, rectify, or revoke consent. Crucially, you possess the full Right to Erasure (Right to be Forgotten)—empowering you to permanently delete your account and expunge all historical research sessions at any time via your account settings or by contacting support@hexsage.ai. We execute irreversible physical deletion within statutory deadlines.
7. Cookies and Local Storage
Our platform utilizes browser localStorage and secure authentication tokens strictly to retain your session state, UI language preference, and display settings. We deploy no cross-site advertising trackers. You can clear local storage and cookies at any time via your browser settings.
8. Revisions, Corporate Entity, and Contact Channels
We may amend this Privacy Policy periodically to reflect technological and legal enhancements. Material updates will be highlighted on this page. For any data protection inquiries or requests, please contact our data privacy officer.
