Network source and cloud drive credentials: When you configure network sources such as SMB, NFS, WebDAV, DLNA, Navidrome, Jellyfin, or Emby, or bind your Baidu Netdisk account, the server addresses, credentials, and OAuth tokens are stored only on your device and used solely to connect to your own servers and drives. They are never sent to us. Baidu Netdisk access is granted via OAuth; we never receive or store your Baidu account password.
Device information: Information such as device model, OS version, and CPU architecture is written only to local logs for compatibility troubleshooting. The App contains no crash-reporting SDK, and this information is not uploaded unless you voluntarily send logs to us when reporting an issue.
Wi-Fi file transfer: File transfers between devices occur peer-to-peer over your local network and never pass through external servers.
