Privacy Policy
Effective September 13, 2026
Saju and Me collects only what a Four Pillars reading needs. Because the service handles details that can feel sensitive, such as your date and time of birth, what we collect, what we use it for and when we delete it are written out below as they are.
1. What we collect
When you sign up with Google or Kakao, we receive an account identifier, name or nickname, email address and profile image within the permissions you grant. If you do not consent to Kakao sharing email or profile information, we do not receive those items. We do not collect your phone number or national ID number.
| Type | Items | Purpose |
|---|---|---|
| Account | Google or Kakao account identifier, name or nickname, email address, profile image and login session | Authentication and connecting records to your account |
| Required | Nickname, gender, date of birth, solar or lunar calendar | Computing the chart |
| Optional | Time of birth, country and city of birth, relationship, occupation | Hour pillar, longitude correction, context for the reading |
| Generated automatically | The chart itself (stems, branches, ten gods, twelve stages, luck and annual pillars) | Grounds for the reading |
| Generated in use | Full text of questions and answers, conversation summaries | Continuing a reading from earlier conversations |
| Generated in use | Model used, token counts, processing cost | Running the service and managing usage |
| Generated in use | A one-way check value made from your IP address and date of birth (the originals are not stored) | Preventing repeated use of the free trial |
| Referrals | Referral code, internal account identifiers for referrer and new user, attribution, first-payment, refund and reward status and time, and a one-way check value—not the payment method itself—to detect repeated payment methods | Confirming referrals, granting rewards and preventing duplicate or fraudulent rewards |
The nickname is only what Hyeon calls you during a reading, so it does not have to be your legal name. If you register a chart for a family member or partner, please make sure you are entitled to enter that person's details first.
What is stored in your browser
So that you return to the chat you were in, we store the chat identifier and your theme setting in your browser. If you open a referral link, a functional cookie stores the referral code and visit time for up to 30 days and is deleted after attribution to your account. We do not use advertising or tracking cookies.
2. What we use it for
- Computing the chart and producing readings
- Remembering earlier conversations so a reading can continue
- Managing usage limits and improving service quality
- Authentication and managing records by account
- Confirming referrals, granting rewards and preventing abuse
- Meeting obligations under applicable law
We do not use it for anything else, and we do not send you marketing email or messages.
3. Processors and transfer abroad
We rely on the following provider to produce readings.
| Provider | Work | Data sent | Retention |
|---|---|---|---|
| Anthropic, PBC (United States) | Generating readings, summarising conversations | The chart, nickname, gender and age, your question and earlier conversation | Destroyed without delay after processing |
Transmission and storage use encrypted connections. You may refuse the transfer abroad, but we cannot produce readings without it, so the service would not be usable.
We do not provide or sell personal data to any third party other than the provider above. Where an investigative authority makes a lawful request under applicable law, we follow that law.
4. How long we keep it, and how to delete it
- A profile and its chart, conversations and memory are deleted immediately along with it when you delete the profile, and cannot be recovered.
- A profile locked by moving to a lower plan is kept, not deleted. Delete it yourself if you want it removed.
- You can also clear only the memorywithout deleting the profile. Choosing ‘Have Hyeon forget me’ from the Hyeon menu on the chat screen immediately and irreversibly deletes what Hyeon has built up about you (facts and feelings learned from your chats, past verdicts, and conversation summaries). The past chats themselves remain under ‘Past conversations’ for your eyes only and are no longer used in readings.
- Under Korean consumer protection law for e-commerce, payment and contract records are kept for 5 years and records of consumer complaints for 3 years. These records do not include the content of readings.
- We keep account information until you delete the account from the in-app account menu. Deleting the account immediately and irreversibly removes its identifiers, profiles, Four Pillars charts, conversations, memories, and sign-in connections.
- Only a technical orphan account whose OAuth sign-up did not complete, has no sign-in connection, and is not linked to any profile, payment, referral, or other data is automatically deleted within 24 hours of creation.
- When Kakao notifies us that you disconnected the service, we delete the Kakao sign-in connection and invalidate all sessions. If another sign-in method such as Google remains, your account and records stay in place and you can sign in again with that method. If Kakao was your only sign-in method, we delete the entire account as described above.
- After account deletion, payment, contract, and complaint records required by law remain for the applicable statutory period. Referral, reward, and anti-abuse records are de-identified, and only the minimum information needed to verify rewards, enforce limits, and prevent abuse is retained.
Payments are not connected yet, so no payment records are created at this time.
5. Your rights
You can view, correct and delete your information at any time. Profile information can be managed directly on the profile screen, and your account can be deleted directly from the account menu. To stop processing or exercise any other privacy right, contact us below. We act on requests without delay.
6. How we keep it safe
- Encryption in transit
- Access to personal data limited to the minimum needed to run the service
- Collecting as little as possible in the first place
7. Children under 14
We do not collect personal data from children under 14 without the consent of a legal guardian. The service is intended for people aged 14 and over.
8. Contact

9. Changes to this policy
When this policy changes, we give notice inside the service from 7 days before it takes effect. Changes that significantly affect you are announced 30 days in advance.
