SimSweep CC Source Tracker captures download URLs and source page URLs only for Sims 4 custom content files (.package, .ts4script) and archives downloaded from known CC sites. All captured data is stored locally in your browser and only transmitted to a localhost server running on your own machine (SimSweep desktop app). No data is collected, stored, or sent to any external server by this extension. When SimSweep submits a source to the shared community database, that happens through the desktop app, not the extension.
