No data leaves this browser. Every file you drop is parsed in memory by JavaScript on this page. There are no network requests, no analytics, no CDN links and no server. You can verify this by opening the page from file:// with the network disconnected, or by watching the browser's Network tab. Nothing is written to disk except the exports you explicitly download. Reloading the page discards everything.

CSV only. Files are identified from their filename and column headers — the five survey exports, evidence-log.csv, tool-inventory.csv and response-tracker.csv. Free-text columns are detected and discarded before anything is computed or drawn.
