Privacy

UStudio is built so that your code stays on your machine. This page explains what the extension does and doesn't do with your data.

No telemetry or analytics

UStudio never sends your code, project files or usage data anywhere. There is no analytics or tracking inside the extension.

License checks (Pro)

Activating, re-validating (about once a week) or deactivating a license contacts the Lemon Squeezy license API (api.lemonsqueezy.com) with your license key and an activation name made of your computer name, the editor name (VS Code / Cursor) and the first 8 characters of the editor's anonymous machine ID (the name you see when managing activations in the customer portal). Trial and license state are stored locally by the editor.

Local connections only

The Live Bridge (Unreal Editor ↔ VS Code / Cursor), the Unreal Editor plugin's Live Coding endpoint and the MCP server (Pro) listen on 127.0.0.1 and require a local token. Browser (cross-origin) requests are rejected.

Files written

• Bridge discovery files: .vscode/.unreal-studio-bridge.json, Saved/UStudio/editor.json and %LOCALAPPDATA%\UnrealStudioWorkflow\bridge.json.
• Index caches in the project's .vscode folder and engine caches in your user profile.
• Local file history snapshots in your temp folder (ustudio-file-history).
