This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application and services. We take your privacy seriously and are committed to being transparent about our data practices.

2. Information We Collect

Facial Images and Biometric Data

We collect the following types of facial data when you use our app:

  • Facial photographs: Front-facing images of your face captured through your device camera
  • Facial geometry measurements: Derived data points including jawline definition scores, facial symmetry ratios, cheekbone visibility measurements, under-eye puffiness levels, and overall facial bloating assessments
  • AI-generated analysis scores: Numerical scores (1-10 scale) for facial definition, jawline prominence, puffiness levels, and bloating reduction progress
  • Progress tracking data: Comparative measurements between multiple photos taken over time
  • Facial feature coordinates: Temporary geometric data points used during AI analysis (automatically deleted after processing)

Important: We do NOT collect biometric identifiers for identity verification, facial recognition, or authentication purposes. All facial data is collected solely for facial improvement analysis and progress tracking.

Third-Party Processing: Your facial images are shared with Google's Gemini AI service to provide core app functionality including facial analysis, debloating recommendations, and progress tracking. This sharing is essential for the app to function properly. Google processes these images according to their privacy policy and does not retain images after analysis completion.
