Client-side by construction — and checkable, not just claimed
The Planning Data Auditor is a web page that reads your Dynamics 365 extract files locally, applies its rule library, and renders findings in the same tab. There is no upload, no account, no login, no cookie, no analytics, and no server that receives anything. Nothing is stored between runs — closing the tab is the delete button.
You do not have to take our word for any of that. Two tests anyone can run: open your browser’s network tab before loading your files and watch no request carry your data anywhere, or pull the network cable (or switch to flight mode) after the page has loaded and run the whole check offline. It works, because there is nothing to send.
What crosses the boundary: nothing. Your extracts, your findings, and the fact that you ran the check all stay with you.
