Privacy Policy

1. What We Collect

• Quiz results — your MBTI type and bias match are stored in your browser's localStorage. If you sign in, they also sync to our Supabase database for cross-device access.
• Account data — if you sign in (optional), Supabase Auth handles your email/OAuth. We store your display name and quiz history.
• Battle votes — your bias battle choices are sent to our database to update the global Elo ranking.

2. AI Features

AI-generated content (tarot, roast, trivia, fortune, group chat, archetype) is processed by our AI provider (Z.AI). Your MBTI type and selected idol names are sent to generate responses. All AI content is clearly labeled as AI-generated. No personal data beyond your MBTI type is transmitted.

3. Third-Party Services

• Supabase — authentication and database (email, quiz results, battle votes)
• Z.AI (GLM) — AI text generation (MBTI type + idol name only)
• Google AdSense — advertising (if enabled)

4. Local Storage & Cookies

We use localStorage to remember quiz results, bias battle appearance counts, and browsing history. Supabase sets authentication cookies if you sign in. We do not use tracking cookies.

5. Your Rights

Clear browser storage to wipe local data. Delete your account from your profile page. Cancel battle participation by not signing in. Contact us for data deletion requests.

6. Children's Privacy

MyBias is designed for general audiences. We do not knowingly collect personal data from children under 13. AI features do not generate romantic or intimate content. If you believe a minor has provided personal data, contact us for removal.

7. AI Disclosure

All personality readings, tarot cards, roasts, fortunes, group chats, and archetype results are AI-generated simulations based on MBTI type data. They are not written by, endorsed by, or connected to any real K-pop idol. Content is for entertainment only.
