1. Information we collect
- Birth chart inputs, such as name or nickname, birth date, birth time, calendar selections, gender, and related reading preferences.
- Contact and account information, such as email address, OAuth profile details, display name, and account status when account features are used.
- Checkout information, such as email, product selected, payment status, order identifiers, refund status, and payment provider metadata.
- Reading content, including prompts, questions, generated reports, share links, comments, likes, and saved library records.
- Technical and usage information, such as IP address, browser, device, time zone, pages viewed, logs, error reports, and security signals.
2. How we use information
- To calculate and display Korean Saju, Four Pillars, five-element, and astrology-style readings.
- To generate free and advanced reports, create shareable result links, and send paid result access links by email.
- To process payments, confirm successful orders, prevent fraud, provide support, and keep purchase records.
- To operate, debug, secure, analyze, and improve the service, including AI prompt quality and product experience.
- To comply with law, enforce our terms, and protect users, the service, and our rights.
3. AI and birth data
Birth information can be sensitive because it may identify personal timing, profile, and relationship details. We use it to provide the reading you request.
When AI-assisted writing is enabled, parts of your submitted input and chart-derived data may be sent to an AI provider to create or improve the written explanation. Do not submit information you do not want processed for this purpose.
4. Payment and email providers
Payments may be handled by Lemon Squeezy or another payment processor. We receive order status and identifiers needed to unlock or deliver the report, but we do not store full card numbers.
Result emails may be sent through an SMTP email provider, Resend, or another email delivery provider. Email delivery metadata may be stored to confirm whether a result link was sent.
5. Sharing and public links
If you create or receive a share link, the result page may be accessible to anyone who has the URL. Shared pages can include chart details, reading text, and other information included in the result.
Avoid sharing a link if the result contains private birth information or personal details you do not want others to see.
6. Cookies and similar technologies
We may use cookies, local storage, session tokens, logs, and similar technologies to keep the service working, remember preferences, support authentication, prevent abuse, and understand usage.
Browser settings may allow you to block cookies, but some features may stop working correctly.
7. When we share information
We do not sell personal information for money.
- With service providers that help us host, operate, secure, process payments, send emails, authenticate users, analyze usage, or generate AI output.
- When required by law, legal process, government request, or to protect rights, safety, security, and fraud prevention.
- In connection with a merger, financing, acquisition, reorganization, or sale of assets, subject to appropriate protections.
8. Retention
We keep information for as long as needed to provide the service, maintain result links, support purchases, comply with legal or tax obligations, resolve disputes, prevent fraud, and enforce agreements.
You may request deletion, but some records may need to be retained where required by law, security, accounting, or legitimate business needs.
9. Security
We use reasonable administrative, technical, and organizational safeguards designed to protect information. No online service can guarantee absolute security.
You are responsible for keeping any account credentials, email account, and shared result links secure.

11. Children
The service is not directed to children. We do not knowingly collect personal information from children where parental consent is required. If you believe a child submitted personal information, contact us so we can review and delete it where appropriate.
12. International users
Your information may be processed in countries other than where you live. Those countries may have different data protection laws. By using the service, you understand that information may be transferred and processed internationally.
