TL;DR: NetGuard does not upload your network scans or create personal profiles. There are no accounts. Recommendations for our other apps use aggregate view and open counts, described below.
NetGuard probes devices on your local WiFi network using TCP port probes and Bonjour/mDNS service discovery. All scanning happens on your device. Results are stored locally on your iPhone in an encrypted database (Apple's SwiftData).
ping or nslookup on a computer.In Settings, the app can fetch up to three recommendations for our other apps. The choices depend on the app you are using, App Store availability and iOS compatibility, not on your personal data or activity inside the app. App icons load from Apple’s image servers. Opening a recommendation takes you to the App Store with a campaign label identifying the source app and placement, never a person.
We count qualified views and successful opens in aggregate. Our service stores daily counts with the source app, recommended app, placement, configuration revision and optional presentation variant. It does not store an account, advertising identifier, device identifier, persistent visitor identifier or personal profile, and it does not receive the app’s private content. These counts cannot tell us who installed an app.
The recommendation service is hosted by Supabase. Network requests necessarily expose an IP address to the hosting provider for delivery and security; our aggregate counter does not store it. See Supabase’s privacy policy. Apple processes icon requests and App Store visits under Apple’s privacy policy.
Your scan results and settings live in NetGuard's app sandbox on your iPhone. Deleting the app deletes that local data. Recommendation counts contain no persistent user identifier and cannot be linked back to your installation. iCloud backup is opt-in via standard iOS Settings.
NetGuard is not directed at children under 13. The app does not ask for a name, account or age. Network scans are never uploaded; aggregate recommendation counts are described above.
If this policy changes, the new version will be posted here and the "last updated" date above will reflect it. Material changes will be announced in-app on the next launch.
