RiskWatch - Privacy Monitoring Android App

RiskWatch is a comprehensive Android application that analyzes the privacy risks of installed applications on your device. It provides users with detailed insights into app permissions, tracking libraries, and overall privacy scores through an intuitive heatmap interface.

Features

📱 Main Dashboard (Privacy Heatmap)

• Color-coded risk assessment: Visual heatmap with red/yellow/green risk indicators
• Filter chips: Quick filtering by risk level (High/Medium/Low) and tracker presence
• App list: Scrollable list of all installed apps with privacy scores
• Real-time scanning: Automatic analysis of installed applications

🔍 App Details View

• Circular progress gauge: Visual representation of privacy risk score (0-100)
• Dual-tab interface:
  • Permissions tab: List of dangerous permissions with plain-language explanations
  • Trackers tab: Identified tracking libraries and their purposes
• Direct settings access: One-tap navigation to app permission settings
• Export functionality: Generate and share privacy reports

⚖️ App Comparison View

• Side-by-side comparison: Compare privacy profiles of two apps
• Permission checklist: Visual comparison of critical permissions
• Privacy score comparison: Easy identification of safer alternatives

🚨 Privacy Alerts Timeline

• Chronological alert feed: Timeline of privacy-related events
• Alert types:
  • High-risk app detection
  • New app installations
  • Permission changes
  • Tracker detection
• Direct navigation: Tap alerts to view detailed app information

⚙️ Settings & Configuration

• Scanning preferences: Configure automatic new app scanning
• Periodic scans: Set up background privacy monitoring
• Offline mode: Disable tracker detection for offline usage

🛠️ Technology Stack

• Language: Kotlin
• UI Framework: Material Design 3
• Architecture: MVVM with LiveData
• Navigation: Navigation Component with Safe Args
• Async Operations: Coroutines
• Permissions Analysis: Android PackageManager APIs
• Tracker Detection: Simulated (extensible for Exodus Privacy API)
• UI Binding: View Binding
• Progress Visualization: Custom circular progress indicators

📊 Privacy Scoring Algorithm

The app calculates privacy scores based on:

• Dangerous Permissions (60% weight): Each dangerous permission adds 10 points
• Tracking Libraries (40% weight): Trackers contribute additional risk points
• Risk Levels:
  • 🟢 Low Risk: 0-39 points
  • 🟡 Medium Risk: 40-74 points
  • 🔴 High Risk: 75-100 points

Setup Instructions

Prerequisites

• Android Studio Arctic Fox (2020.3.1) or newer
• Android SDK API level 24 (Android 7.0) or higher
• Kotlin 1.9.20 or newer

Installation Steps

1. Clone the Repository

   git clone <repository-url>
   cd riskwatch-android

2. Open in Android Studio

   • Launch Android Studio
   • Select "Open an existing project"
   • Navigate to the cloned directory

3. Sync Dependencies

   ./gradlew build

4. Configure Permissions The app requires the QUERY_ALL_PACKAGES permission for comprehensive app scanning. This permission needs to be declared in the manifest and may require special handling on Android 11+.

5. Run the Application

   • Connect an Android device or start an emulator
   • Click "Run" in Android Studio or use:

   ./gradlew installDebug

Building for Release

1. Generate Signed APK

   ./gradlew assembleRelease

2. Create App Bundle (recommended for Play Store)

   ./gradlew bundleRelease
