Privacy Policy for PingVitals

PingVitals ("the App", "we", "us", or "our") is developed with privacy as a fundamental principle. This Privacy Policy explains our practices regarding user information.

1. Zero Personal Data Collection

PingVitals operates 100% locally on your Mac:

• No Personal Information: We do not collect, store, track, or share any personally identifiable information (such as your name, email address, account credentials, or device identifiers).
• Direct User-Configured Network Probes Only: The App sends standard ICMP / ICMPv6 Echo Request ("ping") packets exclusively to the domain names or IP addresses that you explicitly configure in the App to measure round-trip latency and packet loss.
• No Analytics or Telemetry: The App does not contain any third-party analytics libraries, advertising frameworks, crash reporters, tracking scripts, or telemetry services.
• No Developer Servers: We do not operate any backend servers that receive your target host lists, ping results, or usage data.

2. Local Data Storage

All configured host addresses, ping intervals, and 24-hour historical latency records are stored exclusively on your local Mac inside the App's sandboxed Application Support container (SQLite database). This data never leaves your device and can be cleared or deleted by you at any time within the App.

3. macOS App Sandbox & Security

PingVitals is built in full compliance with Apple's macOS App Sandbox guidelines (com.apple.security.app-sandbox). Because ICMP / ICMPv6 Echo probes operate over connectionless datagram sockets (SOCK_DGRAM with IPPROTO_ICMP / IPPROTO_ICMPV6), the App requests com.apple.security.network.client (to send ICMP Echo Request packets) and com.apple.security.network.server (required by the macOS kernel sandbox filter to receive inbound ICMP Echo Reply packets via recvfrom). The App does not open or listen on any TCP or UDP server ports.

4. Children's Privacy

Because the App does not collect any personal data whatsoever, it is fully compliant with the Children's Online Privacy Protection Act (COPPA), GDPR, and other global privacy regulations regarding children under the age of 13 (or applicable age in your jurisdiction).

5. Third-Party Links

The App may contain links to our website (e.g., https://guokai.dev/ping-vitals/) for support or documentation. If you visit any external links, please note that those external websites have their own privacy policies.
