This tool is a local, browser-based proof of concept. It has no backend server and no database.
Any CSV file you upload, and any data generated by the built-in test data tools, is parsed and processed entirely in your browser's memory using JavaScript. Nothing is uploaded to a server, transmitted over the network, or written to any external storage.
When you close or refresh this page, all data is discarded. Nothing is retained between sessions.
Files you choose to download (such as generated sample data or CRM templates) are saved locally to your own device using your browser's standard file download mechanism, and are never seen by us.
