Privacy Policy
Last Updated: July 26, 2026
Yipa (the "App") is operated by Shanghai Chaowei Emerging Technology Consulting Co., Ltd. ("we"). We know your records and hexagram content matter. Privacy is built into the product: that content is encrypted on your devices—we cannot read it in plaintext. We do not sell your personal information or use it for targeted advertising. This Policy explains what we collect, why, how we protect it, and your rights.
1. Scope
This Policy applies to personal information we process when you use the Yipa mobile app, our website (yipa.hyperge.top), and related services. If a specific feature has its own notice, that notice applies to that feature.
2. Information We Collect
We follow a "minimum necessary" approach and collect only what we need to provide the service: [Information you provide] • Account data: e.g., email, for registration, sign-in, and account management • Records and hexagram content: protected with end-to-end encryption in the App; we cannot read plaintext [Information collected automatically] • Device and runtime data: device identifiers, model, OS version, app version • Logs and usage statistics: for security, stability, and troubleshooting • Push-related identifiers: on builds that use remote push (e.g., iOS and Google Play), for service notifications (e.g., when an AI observation is ready); you can disable notifications in system settings [Subscription and payment data] • When you purchase a subscription or in-app item, payment is processed by third parties such as the Apple App Store, Google Play, or WeChat; we do not collect or store your full payment card number • To activate and maintain subscription entitlements and to verify orders and prevent fraud, we may process transaction identifiers, product IDs, subscription status, and expiry dates [What we do not do] • Sell your personal information • Use plaintext records or hexagram content for ads or profiling • Read your end-to-end encrypted content in plaintext
3. How We Use Information
We use collected information only to: • Provide, maintain, and improve Yipa's core features • Authenticate accounts, ensure security, prevent fraud, and troubleshoot issues • Send service-related notifications (you can manage these in system settings) • Personalize your experience where you have consented We process personal information under applicable laws, including bases such as your consent, performance of a contract, and compliance with legal obligations.
4. Storage, Security, and Retention
[Security] We use industry-standard measures to protect personal information we process (such as account data), including encryption in storage and transit. Records and hexagram content use end-to-end encryption; only you hold decryption keys (e.g., your recovery phrase). We cannot access plaintext. Please keep your credentials and recovery phrase safe—loss may prevent recovery of encrypted content. [Location] Your personal information is primarily stored in the People's Republic of China. [Retention] We retain personal information only as long as needed for the purposes in this Policy. After account deletion, we delete or anonymize account-related data within a reasonable period, except where law requires otherwise. End-to-end encrypted content is handled per our deletion process described in the App.
5. Sharing and Processors
We do not sell your personal information. We may share or use processors only when: • You have given explicit consent • Required by law or lawful requests from authorities • Necessary to protect life, property, or other significant legitimate interests of you, us, or other users Third-party SDKs listed in Section 9 are integrated only to provide sign-in, payments, and—on supported builds—message push and similar features. Each processes data under its own privacy policy.
6. Your Rights
Under applicable privacy laws, you may: • Access and obtain a copy of your personal information • Correct or complete inaccurate information • Delete your account and related data (in the App or via support@hyperge.top; we respond within a reasonable time) • Withdraw consent (some features may become unavailable; prior processing based on consent is not affected) • Request an explanation of how we process your information • Manage notification and similar permissions in system settings If you believe our processing infringes your rights, contact us or lodge a complaint with a competent regulator.
7. Children
Yipa is intended primarily for adults. If you are under 18, please read this Policy with a guardian and use the App only with guardian consent. We do not knowingly collect personal information from children under 14 without guardian consent. If you believe we have done so, contact support@hyperge.top and we will verify and delete promptly.
8. AI-Assisted Content
Brief and in-depth observations in Yipa are produced with AI assistance. Outputs are for observation and reference only—not medical, psychological, legal, or financial advice, and not a substitute for professional judgment. Such content is labeled in the App with clear markers such as "AI observation". If you are in crisis or emergency, contact local emergency or mental health services immediately rather than relying on the App.
9. Third-Party SDKs
The App integrates third-party SDKs for sign-in, payments, and—on supported builds—message push. The SDK disclosures below align with China's national SDK registry. Other SDKs we may use include: • Third-party sign-in (e.g., Apple, Google) • In-app purchases (Apple App Store, Google Play, etc.) • Google Firebase Cloud Messaging (Google Play builds only, for message push) Each SDK processes data under its own privacy policy; we integrate them only to provide the related features. Direct-download builds do not use a third-party remote push SDK; service notifications rely on in-app polling and local system notifications.

10. Policy Updates
We may update this Policy from time to time. For material changes, we will notify you through in-app notice, website announcement, or other reasonable means, and seek your consent where required by law before you continue using the service.
