MX Display Switch does not use the network and does not collect telemetry. It opens only the local Logi Bolt HID interface and the Windows monitor DDC/CI API. Configuration and logs remain under the current user's Local AppData.
Please report security issues privately through GitHub's Report a vulnerability feature instead of opening a public issue.
Release binaries are currently unsigned. Windows may therefore display an unknown-publisher warning. Verify the SHA-256 checksums attached to each release before installation.
