ABOUT THE FAIR-USAGE LIMITS
Other WiFi scanners cost $70/year. NetGuard costs $4.99 once. Forever.

HONEST ABOUT iOS LIMITS
The Settings tab has a "What iOS Allows" explainer covering exactly what the OS lets us do and what it doesn't. No surprises.

PRIVACY
Nothing leaves your phone except (1) public-IP lookup to ipinfo.io, (2) speed test against Cloudflare, (3) any ping/DNS you manually run. No analytics. No accounts. No tracking.
