Permissions Explained:

Network Scanner only requests permissions essential for network scanning:
• Network access - To communicate with devices on your network
• WiFi state - To check if you're connected to WiFi
• Nearby WiFi devices - To find devices on your local network. On Android 16 and later, Android requires this permission for all local network communication, so scanning cannot work without it
• Location (optional, never used for tracking) - Only to read your WiFi network name (SSID). Scanning works without it

Network Scanner is completely ad-free, tracker-free, and respects your privacy. All code is open source and auditable.
