Your product data stays in your browser.

CSV files are read and processed locally. The application sends only image URLs when you choose to run availability checks. It does not send product titles, descriptions, SKUs, handles, or the CSV file itself.

Files, reports, and image URLs are never uploaded to or stored on a server. When usage analytics is enabled, it is cookieless and aggregate only: events such as page views, the selected platform, and whether a download happened may be recorded, but never file names, cell values, SKUs, handles, or full image URLs.
