Your file stays in your browser unless you use AI mapping or save your session.
Your product data stays yours.
We do not store your product list by default. Your CSV/XLSX is processed in your browser. Only mapping/report metadata is saved if you choose to save a session. AI mapping sends only headers and a small sample after you ask for it.
