This extension does not collect, store, or transmit any user data to the developer or any third party. Lookup queries are sent directly from your browser to the SharePoint sites you configure, using your existing authenticated browser session. Query results are displayed on screen only and are never persisted or logged. The only data stored is your site configuration (site URLs, list names, and column mappings), which is kept locally in your browser's extension storage and never transmitted anywhere. No analytics, telemetry, or tracking of any kind is used.
