Data Stored on Your Device
- The device list (name, address, port, last connection) is kept in the app’s preferences.
- Device passwords are stored in the system Keychain.
- Remote desktop thumbnails are kept in the local cache folder and may be cleared by the system at any time.
Optional iCloud Sync
Only after you enable iCloud Sync are your computer library and connection settings stored in your private iCloud database, for synchronization between supported devices signed into the same Apple Account. Settings may include computer names, addresses, ports, usernames, and connection preferences.
Connection passwords, SSH private keys, and Tailscale API tokens are not stored in this sync database. Turning sync off stops further synchronization. Deleting a computer propagates its deletion to other devices while sync is enabled.
Network Connections
VNC screen and input traffic may be unencrypted. Use a trusted local network or a configured SSH or Tailscale tunnel. Connection security depends on the protocol, settings, and server capabilities.
Remote desktop connections reach only Macs you add or discover on your local network; discovery uses Bonjour and stays on your local network.
Only when you enter a Tailscale API token and sync devices does the app contact api.tailscale.com to read your Tailnet device list. The token stays in memory for that session and is not written to disk.
From macOS version 1.1.0, manual update checks contact the website feed and download signed packages from GitHub. Requests include compatibility information such as app and macOS versions, not remote screen data, input or device passwords.
