This Privacy Policy explains how Kyun Labs ("we," "us," or "our") collects, uses, and protects your information when you use our AI-powered beauty application, Aura Z.

1. Information We Collect

We believe in data minimization. We only collect the data necessary to provide the service, deliver personalized beauty insights, and ensure app stability.

A. Authentication & Account Data

• Anonymous Access (Default): When you first use the app, we create an anonymous account via Firebase to store your data without requiring personal details such as your name or email address.
• Referral Codes: If you participate in our referral program, a unique referral code is generated and associated with your anonymous account.

B. Biometric & Facial Data

• Selfies & Photos: When you use our face analysis, glow-up transformation, or hairstyle features, you provide photos of your face. These images are processed by AI to generate beauty scores, analyses, and transformed images.
• Facial Analysis Results: We store the results of your facial analyses, including beauty scores, feature-level assessments, and improvement suggestions.
• Progress Photos: If you use the progress tracking feature, we store dated photos and corresponding scores to show your beauty journey over time.
• Important: We do not use facial recognition technology to identify you. Facial data is used solely for the purpose of providing beauty analysis and transformation features within the app.

C. AI Conversations

• Bella Chat History: Conversations with our AI beauty assistant, Bella, are stored to provide contextual and personalized responses within your current and future sessions.

D. User-Generated Content & Cloud Storage

• Generated Images: AI-generated glow-up transformations, hairstyle previews, and other image outputs are stored in our cloud storage infrastructure (Cloudflare R2) and associated with your anonymous account.
• Routine Data: Skincare routines you follow, daily completion logs, streak data, and achievement progress are stored to deliver the routine and gamification features of the app.
