PRIVACY

The checker reads files locally.

CSV scanning happens inside the browser tab. The application has no upload endpoint, account system, analytics tracker or database for transaction data.

What the site receives

Normal hosting request data may be processed by the hosting provider to serve the page and protect it against abuse. The CSV contents selected in the checker are not intentionally transmitted by the application.

Your responsibility

Use a copied, redacted or fictional file while evaluating the checker. Close or refresh the tab to clear the in-memory analysis. Payment and receipts are handled by Gumroad under its own privacy terms.

CSV Preflight is independent and is not affiliated with Intuit or QuickBooks.
