Overview

NetUtil is designed with privacy as a core principle. We don’t collect, store, or transmit any of your personal data.

Data Collection

We don’t collect any data. NetUtil runs entirely on your Mac. All network queries (ping, traceroute, DNS lookups, port scans, etc.) are executed locally and the results stay on your device.

Network Requests

NetUtil makes network requests only when you explicitly use its diagnostic tools:

Ping sends ICMP packets to hosts you specify
Traceroute sends packets with incrementing TTL values
DNS Lookup queries DNS servers for records
Port Scan attempts TCP connections to hosts you specify
Whois queries whois servers for domain information
Netstat reads local system information only

These are the same operations performed by the command-line tools built into macOS. No data is sent to our servers or any third party.

Analytics and Tracking

NetUtil does not include any analytics, telemetry, or tracking code. We have no idea how you use the app, which features you prefer, or how often you open it.

Updates

NetUtil uses Sparkle for update checking. When checking for updates, your Mac contacts our server to download the appcast file. This request includes your IP address (as all web requests do), but we don’t log or store this information.

Third-Party Services

NetUtil does not integrate with any third-party services that would have access to your data.

Changes to This Policy

If we make changes to this privacy policy, we’ll update the “Last updated” date at the top. Significant changes will be noted in the app’s release notes.
