Privacy Policy

1. Introduction

Pro Health Tracker ("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 and web service (collectively, the "Service").

4. Data Storage and Security

• Device-Only Storage: All your health data (lab reports, test results, schedules, medicines, and health metrics) is stored locally on your device — never on our servers
• Authentication Only: Only your login credentials (email and profile info via Google Sign-In) are sent to Firebase for authentication purposes. No health data is transmitted to or stored in Firebase
• Transit Encryption: All data transmitted between your device and external services (authentication, AI analysis) uses TLS 1.2+ encryption
• Biometric Protection: The app supports biometric authentication (fingerprint, face recognition) for an additional layer of local security
• Access Control: Your health data is accessible only on your authenticated device
• No Plain-Text Storage: Sensitive credentials and tokens are never stored in plain text

5. AI-Powered Analysis

Our Service uses artificial intelligence to analyze your lab reports and provide health insights. Here's how it works:

• Lab report data is sent to AI providers (such as Google Gemini, OpenAI, or Anthropic) for analysis only when you explicitly request it
• AI analysis is performed in real-time and results are returned directly — we do not store copies of AI conversations
• AI providers process data under their respective privacy policies and data processing agreements
• You can choose not to use AI features, and the core tracking functionality works independently
