Privacy Policy

Last updated: February 9, 2026

Nunchi Level ("we", "our", "the Service") is operated by DULGI COMPANY. Nunchi Level is a 13-Layer social simulation engine that measures cultural intelligence (Nunchi) through interactive Korean scenarios. This Privacy Policy explains what data we collect, how we use it, and your rights.

1. What We Collect

Account Information (when you sign up):

• Email address
• Display name
• Password (encrypted, we cannot see it)

Quiz & Gameplay Data (when you play):

• Your answer choices in each scenario
• Response time within the 12-second decision window
• Nunchi Level score and personality profile
• Journey progress and episode results

Technical Data (automatically):

• Browser type and language setting
• Device type (mobile/desktop)
• Anonymous usage analytics

2. What We Do NOT Collect

• Real name, phone number, or physical address
• Payment or financial information
• Location data (GPS)
• Contacts, photos, or files from your device
• Third-party tracking cookies

3. How We Use Your Data

• Provide the Service — Calculate your Nunchi Level, generate your Nunchi Passport (shareable result card), and save your journey results.
• Behavioral Analysis — Your response times and choice patterns within the 12-second decision window help us understand cultural decision-making. This data is always anonymized before analysis.
• Improve the Service — Analyze aggregated, anonymized response patterns to improve scenario quality and cultural accuracy.
• Communicate — Send essential account emails (password reset, etc.). We do not send marketing emails.

4. Data Storage & Security

Your data is stored on Supabase (cloud infrastructure hosted in the US/EU). Passwords are encrypted using industry-standard hashing. We implement Row-Level Security (RLS) so users can only access their own data. Your behavioral data (response times, choice patterns) is stored separately from your personal information and linked only through anonymized identifiers.

5. Data Sharing

We do not sell, rent, or share your personal data with third parties. Anonymized, aggregated statistics (e.g., "average Nunchi Level by region" or cultural response patterns) may be used for academic research or published in reports, but individual users are never identifiable.

6. Your Rights

• Access — You can view your data in your account.
• Delete — You can request account deletion by emailing us. We will delete all associated data within 30 days.
• Export — You can request a copy of your data.

7. Age Requirement

You must be at least 14 years old to create an account. If you are under 14, you need permission from a parent or legal guardian. If we learn that we have collected data from a child under 14 without parental consent, we will delete it promptly.

8. Cookies

We use only essential session cookies to keep you logged in. We do not use advertising or tracking cookies.

9. Changes

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the Service after changes constitutes acceptance.
