Privacy Policy

1. Scope and controller

ZNAI, L.L.C. ("Dawnvane," "we," "us") controls personal data processed through dawnvane.com and the related Book and Agent services. This policy applies to users aged 18 or older.

2. Information we collect

• Account data: identifiers and basic profile information returned by the sign-in provider, such as an email address.
• Birth profile: birth date, local birth time, birthplace, gender used for traditional luck-cycle direction, and an optional nickname.
• Derived content: deterministic Bazi chart facts, five-element percentages, timing data, generated Book content, questions, Agent answers, and conversation history.
• Commerce data: product, price, currency, order status, and Stripe transaction references. Dawnvane does not receive or store full payment-card numbers.
• Technical data: security, error, and request metadata reasonably needed to protect, debug, and operate the service.

3. How we use information

We use data to authenticate accounts, resolve birthplace and timezone, calculate the chart, generate and deliver a Book, answer one Agent turn at a time, maintain entitlements, prevent duplicate charges or abuse, provide support, and comply with law.

Dawnvane does not sell personal information or use it for targeted advertising.

4. Deterministic charting and AI processing

The Bazi chart and five-element calculations are deterministic software operations. They do not use a language model, and the model cannot recalculate or override the selected chart.

For a paid Book or Agent answer, the reviewed payload may send derived chart facts, your optional nickname, your current question, a bounded portion of successful conversation history, and relevant reviewed knowledge excerpts to DeepSeek. The payload is designed not to include the raw birth date, birth time, birthplace, or gender fields. DeepSeek is operated in the People's Republic of China, so this processing may occur outside your country, including in China.

5. Place and payment providers

For a mainland-China birthplace, Dawnvane may send the entered place label to Amap to resolve it to district level. For an overseas birthplace, Dawnvane may send the city label and coordinates to Google Maps Platform to resolve city and timezone. Birth date, birth time, gender, nickname, Book text, and chat questions are not sent to these place providers for that lookup.

Stripe processes checkout and payment information under its own privacy practices. Dawnvane relies on Stripe's signed server notification—not a browser return page—to grant a Book or conversation entitlement.

6. Retention

• Birth-profile data and delivered Books: retained while the account remains active, unless a shorter period is required by law or requested by you.
• Conversation content: up to 12 months.
• Security and operational logs: up to 90 days.
• Payment, tax, accounting, and fraud-prevention records: up to 7 years where reasonably required.
• After a verified deletion request, encrypted content is removed or rendered inaccessible in the primary database promptly; residual backup and cache copies are scheduled for deletion within 30 days, unless law requires limited retention.

7. Security and sharing

We use access controls, encryption, signed requests, limited-purpose service accounts, and payment-webhook verification. No internet service can guarantee absolute security. We share data only with processors needed to operate the service, professional advisers, a successor in a lawful business transaction, or authorities when legally required.

8. Your choices and rights

Depending on where you live, you may request access, correction, deletion, portability, restriction, objection, or information about disclosures. You may also ask us not to use optional data. We will not discriminate against you for exercising a legal privacy right.

Send a request from the email associated with your account to scarlettzhang93@gmail.com. We may verify identity before acting. We may retain limited records where required for transactions, security, legal claims, or compliance.

9. International use and changes

Our providers may process data in countries with different privacy laws. Where applicable law requires a transfer safeguard or additional consent, we will apply it before offering the relevant processing. Material policy changes will be posted here with a new effective date.
