How we handle your data
The short version: we don't. Your file never reaches us.
What happens when you drop a file
This site is a static page. Once it has loaded, all the work — reading your file, computing the bridge, building the exports — happens inside your browser, on your machine. There is no server-side processing, because there is no server-side application to send anything to.
- No upload: the contents of your file are never transmitted anywhere.
- No account, no email, no sign-up.
- No cookies, no analytics, no tracking pixels, no third-party scripts.
- Nothing is stored once you close the tab.
Don't take our word for it — verify it
You can check this claim yourself in about two minutes:
- Chrome / Edge: press F12 (or Ctrl+Shift+I, Cmd+Option+I on Mac), open the Network tab.
- Firefox: press F12, open the Network tab.
Keep the panel open, then use the app end to end: drop your file, map the columns, read the results, download the Excel export. Watch the request list — after the page assets have loaded, no request carries your data anywhere. If any request ever carried your data, it would appear in that list — and none ever does.
Why we built it this way
Sales data at SKU level is among the most confidential data a company holds. Company policies rightly forbid pasting it into random websites and AI chatbots. The only design that genuinely resolves that tension is one where the data physically cannot leave your machine — so that is the design we chose, and we make it verifiable rather than asking for trust.
