First Launch

When you first open Necron Vault Manager, you'll be greeted by the Gatekeeper screen. The app first scans for connected Key Drives.

Gatekeeper scanning for Key Drives

If none are found, you'll see the "NO KEY DRIVE DETECTED" prompt with two options:

Gatekeeper with no Key Drive detected

  • Insert a Key Drive — if you have a Necron-provisioned Key Drive, plug it in. The app detects it automatically, verifies it with the server, and proceeds to the main interface.
  • Enter Free Tier — log in with your email and password to activate the built-in software key. This provisions a local key with 20 MiB of random key material stored on your computer.

Tip

You can always upgrade from Free to Pro later by purchasing a subscription and provisioning a Key Drive. Your existing encrypted files remain fully compatible.

Where Files Are Stored

Necron Vault Manager stores its configuration and software key data in your user profile:

Data Windows macOS Linux
Software key (Free tier) %LOCALAPPDATA%\keymanager\demo\ ~/Library/Application Support/keymanager/demo/ ~/.local/share/keymanager/demo/
Application settings %LOCALAPPDATA%\keymanager\ ~/Library/Application Support/keymanager/ ~/.local/share/keymanager/
Vault data User-chosen directories User-chosen directories User-chosen directories

Warning

Do not manually move or edit files in the application data directory. The software key is encrypted at rest and bound to your user account — moving it to another machine will make it unusable.

Uninstalling

Windows

Open Settings → Apps → Installed apps, search for "Necron", and click Uninstall.

macOS

Drag Necron Vault Manager from Applications to the Trash.

Linux

Run sudo dpkg -r necron-vault-manager or delete the AppImage file.

Danger

Uninstalling the application does not delete your encrypted files or vault data. However, if you are using a software key (Free tier), the key data may be removed. Make sure you have decrypted any important files before uninstalling.
