SolidFerry is a local desktop app. It has no accounts, no cloud service and no telemetry.

• Devices: it talks to Android devices over USB (MTP, directly through IOKit) and through the local adb server (127.0.0.1:5037). With wireless debugging, adb connects to the device over your local network.
• Network: the only download is Android SDK Platform-Tools from dl.google.com, and only when you ask for it (when no adb is installed). It is saved in the app's own Application Support folder.
• Files: it reads and writes only the files you choose to transfer, plus temporary files (.*.xfer-part next to a download in progress, and its own temporary folder).
• Sandbox: the app runs without the App Sandbox, because it needs the adb server socket and raw USB access. To take the MTP interface from macOS's ptpcamerad it may end that process (it is restarted by the system), and on request it can turn ptpcamerad off for your user with launchctl. Both are described in docs/QUIRKS.md (H1–H3).
