TL;DR: NetGuard is a local network scanner you run on your own WiFi. Use it only on networks you own or are authorized to scan. It's provided as-is, with no warranty.
By downloading or using NetGuard ("the app"), you agree to these Terms of Service. If you do not agree, do not use the app.
NetGuard scans the local WiFi network your iPhone is connected to, discovers devices, and provides network diagnostic tools (ping, DNS lookup, public-IP lookup, speed test, and, with NetGuard Pro, port scanning, traceroute, Wake-on-LAN, new-device alerts, device naming, and CSV export). All scanning runs on your device.
NetGuard Pro is a one-time, non-consumable in-app purchase that permanently unlocks the Pro features listed above on your Apple ID. There is no subscription and no recurring charge. Payment is processed by Apple through the App Store; purchases are subject to the Apple Media Services Terms and Conditions. You can restore a previous purchase at any time using the "Restore Purchases" button on the paywall. Refunds are handled by Apple, not by us.
NetGuard collects no personal data and has no accounts or servers. See our Privacy Policy for details.
The app is provided "as is" and "as available" without warranties of any kind, express or implied. Network diagnostics are best-effort; iOS restricts certain low-level network operations, and results may be incomplete or approximate. We do not warrant that the app will be error-free or uninterrupted.
To the maximum extent permitted by law, the developer shall not be liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, the app.
These terms may be updated from time to time. The "last updated" date above will reflect any changes. Continued use of the app after changes constitutes acceptance.
