Privacy Policy

Last updated: 11 May 2026

K-SAJU is an entertainment service. Readings are generated by artificial intelligence and are provided for entertainment and self-reflection purposes only. They do not constitute professional, medical, financial, or legal advice.

1. Who We Are

K-SAJU is operated by:

Operator: TAEHOON LEE
Address: D16, Dublin, Ireland
Contact: [email protected]
Website: saju-ai.app

We are the data controller for personal data processed through this website.

2. What Data We Collect and Why

Birth information (date, time, gender) — entered by you to generate your saju reading. This is processed in memory during analysis and is not stored in association with your identity. Only birth date, time, and gender are retained in our database as part of the reading record; your name is replaced with an anonymous placeholder before storage.

First name or nickname — used within the reading text for a personalised experience. Before saving, all names are replaced with anonymous placeholders (e.g. {{user_1_name}}) so no names are stored on our servers.

Email address — collected at the time of payment, used solely to deliver your result link via email. Your email address is passed directly to our email provider (Resend) and is never written to our database.

Payment data — processed entirely by Stripe. We store only a payment reference ID (Stripe Payment Intent ID) and payment status. We never see or store your card details.

Usage data — standard server logs (IP address, browser type, timestamp) may be collected automatically by our hosting infrastructure for security and operational purposes. These logs are not used for profiling or advertising.

3. Legal Basis for Processing (GDPR)

Contract performance — processing birth information and email to deliver the service you paid for (Art. 6(1)(b) GDPR).
Legitimate interests — server logs for security and fraud prevention (Art. 6(1)(f) GDPR).

4. Third-Party Services

We use the following third-party processors:

Google Gemini (Google LLC) — AI model used to generate reading narratives. Birth information (date, time, gender) is sent to Google's API. Subject to Google's Privacy Policy.
Stripe (Stripe, Inc.) — payment processing. Subject to Stripe's Privacy Policy.
Resend (Resend, Inc.) — transactional email delivery. Your email address is passed to Resend to send your result. Subject to Resend's Privacy Policy.

We have Data Processing Agreements in place with each of these processors where required by GDPR.

5. Data Retention

Reading records — stored indefinitely so your result link remains accessible. Records contain only birth data and anonymised placeholders (no names, no email).
Payment records — Stripe Payment Intent ID and status retained for accounting and legal compliance purposes (typically 7 years).
Email address — not stored; discarded immediately after the email is sent.
Server logs — retained for up to 30 days by our hosting provider.

6. Cookies and Local Storage

K-SAJU does not use tracking cookies. We use browser localStorage to store your archive of readings on your own device. This data never leaves your device unless you explicitly share a result link.

7. Your Rights (GDPR)

If you are located in the European Economic Area (EEA) or the UK, you have the following rights:

Right of access — request a copy of personal data we hold about you.
Right to rectification — request correction of inaccurate data.
Right to erasure — request deletion of your data ("right to be forgotten").
Right to restriction — request that we limit how we process your data.
Right to data portability — receive your data in a structured, machine-readable format.
Right to object — object to processing based on legitimate interests.

To exercise any of these rights, contact us at [email protected]. We will respond within 30 days.

You also have the right to lodge a complaint with the Data Protection Commission (Ireland): dataprotection.ie.

8. International Transfers

Some of our third-party processors (Google, Stripe, Resend) are based in the United States. Transfers to the US are made under Standard Contractual Clauses (SCCs) as provided by the European Commission, or under other appropriate safeguards.

9. Children

K-SAJU is not directed at children under 16. We do not knowingly collect personal data from anyone under 16. If you believe a child has submitted data to us, please contact us and we will delete it promptly.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page will reflect any changes. Continued use of the service after changes constitutes acceptance of the updated policy.
