This Privacy Policy describes how Hunter Eyes ("we," "our," or "us") collects, uses, and protects your information when you use our mobile application (the "App"). We are committed to protecting your privacy and being transparent about our data practices.
Important: This App uses both on-device processing and cloud-based AI services. Please read this policy carefully to understand how we handle your information.
Hunter Eyes processes facial data through two distinct systems:
On-Device Analysis (Vision Framework):
Facial landmark coordinates for symmetry analysis
Geometric measurements and proportions
Symmetry calculations and scores
Analysis visualizations and overlays
Cloud-Based AI Analysis (Firebase Vertex AI):
Processed facial images sent to Google's Vertex AI service
AI-generated analysis of facial characteristics
Structured analysis results and recommendations
On-Device Processing:
Facial symmetry analysis using Apple's Vision framework
Real-time measurement calculations
Overlay generation and visualizations
No internet connection required for basic analysis
Cloud-Based AI Processing:
Enhanced AI analysis using Google's Gemini models via Firebase Vertex AI
Images are processed by Google's secure cloud infrastructure
AI-generated insights and detailed recommendations
Requires internet connection for AI features
We share facial images with Google LLC through their Vertex AI service (accessed via Firebase) for enhanced AI analysis features.
To provide advanced AI-powered facial characteristic analysis
To generate detailed recommendations based on facial features
To offer comprehensive facial symmetry and aesthetic assessments beyond basic on-device capabilities
To enable enhanced machine learning analysis that cannot be performed locally
Google's Data Handling:
Google may temporarily store facial images during AI processing according to their Vertex AI service terms
Images are processed on Google's secure cloud infrastructure
Google's handling of face data is governed by their Privacy Policy at https://policies.google.com/privacy
Google's AI services terms apply to all data processing
Retention Period:
Google processes face data according to their standard data retention policies for AI services
Specific retention timeframes are governed by Google's Privacy Policy and Vertex AI service terms
Images are typically processed and then deleted, but exact timeframes are determined by Google's policies
Purpose of Google's Storage:
Temporary storage for AI model processing and service delivery
Quality assurance and service improvement as outlined in Google's terms
Compliance with Google's technical and legal requirements
We share facial images only with Google LLC through Vertex AI service for AI analysis features
We do NOT share facial data with advertising networks, data brokers, or any other third parties
No selling, renting, or trading of facial information to any party
No integration with external facial recognition services beyond Google's AI service
You can opt out of AI analysis features to avoid any face data sharing with Google
