CSV Preflight needs no account and processes selected files locally on your Mac. The app implements no file upload, analytics, telemetry, tracking, or third-party SDKs. It makes no network requests.
Selected files are read for inspection. Reports are written only to the destination you choose. Inspection data is processed in memory. File contents are not sent to the developer.
