Privacy Policy

1. Information We Collect and Process
1) Sign-in: account identifier, email address, display name and profile image URL. Your first sign-in creates a member account.
2) Entered details: birth date, birth time and birthplace, gender, solar/lunar calendar and optional MBTI. Profile details entered or changed while signed in are automatically stored on our server for return visits and use across devices; they may also remain in browser storage.
3) AI readings: analysis data, questions, conversation and reading results are transmitted to and processed by our server and AI service, and stored on our server. Compatibility requests may include the other person’s entered Saju details and optional MBTI; only enter information you may lawfully provide.
4) Usage and payments: visits, clicks and other usage records, access logs, referral information, language, country code, and payment, refund and credit records. Payment providers handle payment credentials; we do not directly collect or store full card numbers or card passwords.
5) Optional notifications: consent history, push subscription details and the Saju details used for notifications. Marketing updates and browser notifications are used when you choose them.
6) Ink-and-wash portrait (optional): if you choose it, one photo you take or choose and the finished painting.

2. Purposes of Processing
1) Sign-in, user identification and service provision
2) Restoring entered details, Saju, compatibility and AI readings, and resuming readings
3) Managing credits, payments, refunds and access, and resolving errors
4) Service improvement, usage statistics and your chosen updates and notifications

3. Retention Periods
1) Account and Saju profile: deleted when you delete your account.
2) AI requests, conversations and readings: even unsaved records are stored for recovery and error handling, and records older than 30 days are regularly removed. Readings you choose to save are retained until deleted or your account is deleted. Saved year-ahead readings are released from saved status after their target year ends and are then subject to cleanup.
3) Browser-stored information may remain after you close the window. You can remove it using your browser’s site-data settings.
4) Transaction records subject to statutory retention, including contract and payment records, are kept for five years. Payment and usage records are disconnected from your member account on account deletion; information required by law is retained for the mandated period.
5) Ink-and-wash portrait: the photo is not kept. Up to three finished paintings made with a credit are kept in My ink-and-wash portraits in your account and are deleted when you delete them there or delete your account. Our operator may view it to answer your enquiries and check quality. The request time, whether it was finished and whether a credit was used remain in usage records.
6) Portrait on a saved reading: a saved reading that includes face reading shows the ink-and-wash portrait you chose as your main portrait, on any device signed in to that account. The free face-reading diagram is not attached to readings. Deleting a saved reading leaves your portraits in place.

4. External Services and Information Processing
We do not sell personal information. We use Supabase for authentication and data storage, Google Gemini for AI readings, Vercel for hosting, Toss Payments and PayPal for payments, and Google Analytics for usage statistics. Information needed for each function is processed by the relevant service. When you request an AI reading, your analysis data, questions and conversation are sent to the AI service. If you choose an ink-and-wash portrait, one photo you take or choose is sent to Google Gemini to paint it. Any disclosure required by law is handled under applicable law.

5. Data Deletion
Information is deleted without delay when its retention period expires or its processing purpose is fulfilled. Records that must be retained by law are managed only for the applicable purpose.

6. Your Rights and Account Deletion
Contact the customer support email below to request access, correction, deletion or suspension of processing. To delete your account yourself, sign in and select “Delete account” at the very bottom of the main page, below the business and customer support information, then confirm with “Delete my account”. Your account, Saju profile, readings and remaining credits are deleted and cannot be recovered. Statutory transaction records and usage records disconnected from your member account are managed under the retention rules above. Please request any eligible refund before deleting your account. Account deletion does not itself remove statutory refund rights.

7. Cookies and Analytics
We use cookies, browser storage and Google Analytics to maintain sign-in, restore entered details and measure usage. You can reject cookies or delete site data in your browser settings; doing so may affect sign-in persistence and restoration of details.

8. Information We Do Not Collect and Face Images
We do not collect your sign-in account’s password, email contents or contact list. Face-reading camera images and full facial coordinates are processed only in your browser and are not transmitted to or stored on our server. The camera is used only with your permission. The exception is the ink-and-wash portrait: if you choose it, one photo you take or choose passes through our server to Google Gemini to paint the portrait. We do not store that photo. Google does not use data received through its paid API to improve its products and keeps it only for a limited time to check for misuse. If you choose to include face reading in Saju or compatibility, measurement categories, ratios and an interpretation summary are sent to our server and AI service as part of that AI request and stored with the reading records.
