REQUIREMENTS

What you will need

  • Windows 11, 64-bit

  • Your phone and PC on the same Private network
  • Windows Firewall permission for Private networks only
  • A current GridCue mobile app
INSTALLATION

How installation will work

  1. Download the signed installer from this page.
  2. Verify the published SHA-256 checksum.
  3. Install for the current Windows user.
  4. Choose the LMU root and an existing setup destination.
  5. Open a short pairing window and scan its QR code in GridCue.
SECURITY

Strict by design

  • No Public-network listener
  • No arbitrary commands, paths, URLs, or launch arguments
  • Only bounded .svm setup files
  • SHA-256 and file-size verification
  • No overwrite without an explicit safe workflow
  • Device-bound pairing that can be revoked
UPDATES + REMOVAL

You stay in control

Every public version will include release notes, a checksum, and a supported update path. GridCue Companion can be removed from Windows Settings. Removing it stops the local service; revoke the old pairing in GridCue as well.
