      <h1>Privacy Policy</h1>
      <p class="meta">Effective date: 28 July 2026<br />Applies to PacketCircle for iOS and macOS</p>
      <p>
        PacketCircle (“the App”) is provided by <strong>Walter Hofstetter / netwho</strong>
        (“we”, “us”). This policy explains how the App handles information.
      </p>
      <h2>1. Summary</h2>
      <ul>
        <li>The App does <strong>not</strong> require an account.</li>
        <li>Packet captures you open or record are processed <strong>on your device</strong>.</li>
        <li>We do <strong>not</strong> operate a PacketCircle cloud service that receives your capture files.</li>
        <li>We do <strong>not</strong> sell your personal information.</li>
      </ul>
      <h2>2. Information the App processes</h2>
      <p>Depending on how you use PacketCircle, the App may process:</p>
      <ul>
        <li><strong>Capture files</strong> you choose to open (for example PCAP / PCAPNG), including network addresses, ports, protocols, and payload bytes present in those files.</li>
        <li><strong>Live capture data</strong> (macOS), if you start a capture on a network interface you select.</li>
        <li><strong>App preferences</strong> stored locally on your device (for example display options).</li>
      </ul>
      <p>
        Network captures can contain sensitive or personal data about you or others.
        You are responsible for how you obtain, store, share, and delete those files,
        and for complying with applicable laws where you use the App.
      </p>
      <h2>3. How information is used</h2>
      <p>On-device processing is used only to provide App features, such as:</p>
      <ul>
        <li>visualizing communication pairs,</li>
        <li>showing traffic statistics and session quality estimates,</li>
        <li>decoding frames and following TCP streams,</li>
        <li>exporting or saving captures you choose to save.</li>
      </ul>
      <h2>4. Data sharing</h2>
      <p>
        We do not sell your data. The App does not upload your capture files to our servers.
        If you use optional system features (for example sharing a file via AirDrop, Files,
        Mail, or opening a capture in another app such as Wireshark on Mac), those actions
        are controlled by you and subject to the other product’s terms and privacy policy.
      </p>
      <p>
        Apple may collect diagnostic or usage information according to your device settings
        and Apple’s privacy policy when you install apps from the App Store or use TestFlight.
      </p>
      <h2>5. Data retention &amp; deletion</h2>
      <p>
        Capture files and preferences remain on your device (or in locations you choose)
        until you delete them. Uninstalling the App removes App data stored in the App’s
        container; files you saved elsewhere (Downloads, Files, iCloud Drive, etc.) remain
        until you delete them there.
      </p>
      <h2>6. Children</h2>
      <p>
        The App is not directed at children under 13 (or the minimum age required in your
        country). Do not use the App to collect personal information from children.
      </p>
      <h2>7. International users</h2>
      <p>
        Because processing happens on your device, your data generally stays under your
        control on that device. If you back up or sync files with third-party services
        (for example iCloud), their policies apply.
      </p>
      <h2>8. Changes to this policy</h2>
      <p>
        We may update this Privacy Policy from time to time. The “Effective date” above
        will be revised when changes are posted at this URL.
