🛠️ Technical Details

Architecture

• SwiftUI - Modern declarative UI framework
• Network Framework - Native macOS network statistics
• Combine - Reactive data flow for real-time updates
• UserDefaults - Persistent storage for cumulative statistics

How It Works

The app monitors network interface statistics using macOS's built-in network monitoring capabilities. It:

1. Reads system-level network byte counters
2. Calculates speed by measuring changes over time
3. Updates the UI in real-time (1-second intervals)
4. Persists cumulative totals to UserDefaults

🛡️ Privacy

This app is designed with privacy in mind:

• ✅ Only monitors network statistics from your system
• ✅ Does NOT collect or transmit any personal data
• ✅ Does NOT track your browsing activity or inspect traffic content
• ✅ Does NOT require internet connection
• ✅ All data stored locally on your Mac using UserDefaults
• ✅ No analytics, tracking, or third-party services

See PRIVACY.md for complete privacy policy.
