Privacy Policy
Last updated: January 29, 2026
Introduction
Vertex Face Lab ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application Vertex Face Lab (the "App").
Information We Collect
TrueDepth Camera and Face Data
Vertex Face Lab uses the Apple TrueDepth camera and ARKit framework to provide real-time facial tracking for exercise guidance. When you use our facial tracking features, we process the following data locally on your device:
- Blend Shape Coefficients: Numerical values (0.0 to 1.0) representing 52 facial muscle positions
- Head Pose Data: Pitch, roll, and yaw angles indicating head orientation
- Face Mesh Geometry: 1,220 vertex positions for rendering visual overlays
Important: We do NOT capture photographs, images, face prints, or biometric identifiers. All face data consists of numerical coefficients processed locally on your device by Apple's ARKit framework.
TrueDepth Camera Usage: Data from the TrueDepth camera is used solely to provide real-time facial exercise feedback. This data is processed entirely on your device, is never transmitted off-device, is not stored persistently, and is not used for facial recognition, authentication, or any form of user identification.
Other Information
- Progress Photos: Stored locally in your device's photo library only
- Session Data: Exercise records stored locally on your device
- Analytics: Anonymized usage statistics (never includes face data)
How We Use Your Information
Facial tracking data is used exclusively for:
- Real-time exercise guidance and feedback
- Calculating posture symmetry and alignment metrics
- Rendering mesh visualizations during sessions
- Displaying real-time metrics to help you improve
We do NOT use face data for:
- Facial recognition or identification
- Creating biometric profiles or templates
- Authentication or security purposes
- Advertising, marketing, or user targeting
- Training machine learning models
Data Storage and Retention
Face Data Retention: ZERO
Face data is NOT stored. It is:
- Processed in real-time during active camera sessions only
- Held only in volatile device memory
- Never written to disk or persistent storage
- Immediately discarded when tracking stops or app closes
- Not recoverable after the session ends
We do not store any user data in the cloud. All data remains on your device.
Data Sharing and Disclosure
We do NOT share, sell, rent, or transmit your facial tracking data to any third parties. All facial processing occurs locally on your device. No face data ever leaves your device.
Third-Party Services
- Apple ARKit: Face tracking processed on-device only
- RevenueCat: Subscription management (receives transaction data only, never face data)
Summary of Face Data Practices
| Collection | 52 blend shape coefficients + head pose (numerical data only) |
| Storage | None - processed in real-time only |
| Retention | Zero - discarded immediately when session ends |
| Sharing | Never shared with any third parties |
| Purpose | Real-time exercise feedback only |
| Biometrics | No biometric identifiers created or stored |
Your Rights
You can revoke camera access anytime in Settings. To delete local data, use "Reset All Progress" in app Settings or reinstall the app.
