How your data is handled
All validation runs locally in your browser using JavaScript. Your KQL queries never leave your machine — there is no server, no API calls, and no analytics. Nothing is stored in cookies, localStorage, or any other persistent storage. When you close this tab, everything is gone. The complete source code is open source on GitHub.
