Bitfield Creek Labs Windows installers are digitally signed using Microsoft Azure Artifact Signing. The certificate is issued to Halo Softworks LLC — our registered company name — so that is the publisher Windows shows. A valid signature confirms that the installer came from us and has not been modified since it was signed.
If Windows shows a security prompt, confirm the publisher is Halo Softworks LLC before continuing.
Before running the installer, confirm the following details.
Check the digital signature in Windows Explorer
- Right-click the downloaded installer.
- Select Properties.
- Open the Digital Signatures tab.
- Select the Halo Softworks LLC signature.
- Choose Details.
- Confirm that Windows reports that the digital signature is valid.
Check with PowerShell
Get-AuthenticodeSignature .\AuraTerran-Setup-1.12.30.exe | Format-List *
Expected: Status: Valid and a signer/publisher of
Halo Softworks LLC.
Check the SHA-512 checksum
Get-FileHash .\AuraTerran-Setup-1.12.30.exe -Algorithm SHA512
Compare the Hash value with the SHA-512 shown above (case-insensitive).
If Windows SmartScreen shows a reputation notice, select More info to reveal the publisher. Continue only when it reads Halo Softworks LLC and the installer came directly from the Bitfield Creek Labs website; otherwise delete the file. Bitfield Creek Labs does not recommend disabling SmartScreen.
- Install — run the setup wizard and launch from the Start menu
- Add docs — create a namespace and drag in files or folders
- Search — query from the built-in UI; connect MCP or REST when ready
The app auto-updates after install. On-device embeddings work out of the box. Installing accepts the End User License Agreement. Need help? See the setup guide or contact Bitfield Creek Labs.

What installs, and how to remove it
What Aura Terran Knowledge puts on your machine
- A Windows application — a standard setup wizard (.exe or .msi) that shows the
EULA, lets you choose the install folder (default
%LOCALAPPDATA%\Programs\Aura Terran), and adds Start menu and desktop shortcuts. - Your knowledge bases and settings — indexed documents, embeddings, app settings,
your license or trial record, a local request log, and a random device identifier live under
%USERPROFILE%\.aura-terran. Documents are indexed on this PC and are not uploaded. - Embedding model files — the first time you index, the app downloads the
on-device embedding model (a few files from
huggingface.co) into%USERPROFILE%\.aura-terran\models. Only the model is downloaded; none of your documents are sent. After that, indexing and search work offline. - App cache and update files — the app framework keeps window state and cache
under
%APPDATA%\aura-context-hub(the app’s internal folder name) and downloaded updates under%LOCALAPPDATA%\aura-context-hub-updater. - Local network ports — the Management API (default
41800), inbound MCP (default41801), and optional passthrough listeners listen on127.0.0.1only, with bearer-token authentication on by default, so tools on this PC can query your corpus.
What it does not do
- No changes to your browser, proxy, or system settings. No driver, no certificate.
- No third-party programs are installed; the app’s own runtime and search backend run only inside Aura Terran Knowledge. While running, the app checks our release feed about every four hours, downloads a new version in the background, and installs it when you close the app. Updates replace only Aura Terran Knowledge.
- Your documents stay on this PC unless you turn on optional remote model providers, web search, or external tools — those send request text to the services you configure, under their terms.
- The app sends a few de-identified events: install succeeded (from the installer), session start and end with approximate run time, and one uninstall notice — each with the app version, an OS label, and a random device identifier. Trial start and license activation send the product, that device identifier, the app version, and (for activation) your license key. Crash reports go out only if you click Send. None of these include documents, file names, or search text. Details in the Privacy Policy.
-
It edits another program’s settings only when you ask: the one-click MCP setup adds an
aura-terranentry to Cursor’s~/.cursor/mcp.jsonor Claude Desktop’s config file.
How to remove it completely
- Open Windows Settings → Apps → Installed apps, find Aura Terran Knowledge, and choose Uninstall. The standard Windows uninstaller removes the program and shortcuts and sends the single de-identified uninstall notice mentioned above.
-
Delete
%USERPROFILE%\.aura-terranto remove your knowledge bases, settings, license record, and the cached embedding model. -
Delete
%APPDATA%\aura-context-huband%LOCALAPPDATA%\aura-context-hub-updaterto remove the app cache and any downloaded update. -
If you used the one-click MCP setup, remove the
aura-terranentry from Cursor’s or Claude Desktop’s MCP config.
After these steps nothing from Aura Terran Knowledge remains on the machine.
Windows showed a SmartScreen prompt. What now?
Microsoft Defender SmartScreen warns about installers it has not seen often yet. It is a reputation notice, not a malware detection. Our installers are digitally signed by Halo Softworks LLC (the legal name of Bitfield Creek Labs); the certificate is new, so it has little download history.
- Do not continue until you can see the publisher. Windows hides it until you select More info.
- Confirm the publisher reads Halo Softworks LLC and that you downloaded the file from this site. If either is not true, delete the file and download again from this page.
- If both check out, you can allow the installer to run. Optionally verify the signature and SHA-512 checksum first.
Bitfield Creek Labs does not recommend turning SmartScreen off. Verify the publisher instead.
