This page covers the Excel Round-Trip extension for Azure DevOps, made by LeDuc Systems LLC ("I" below; I run the company myself).

Where your data is stored

Work items are read from and written to Azure DevOps in your browser, using the Work items (read and write) scope.
Workbooks are created and read in your browser. The file you download is saved where your browser saves downloads.
Undo logs (the previous values of fields an import changed, and the IDs of items it created) are stored in your Azure DevOps organization's extension data storage at user scope. If that storage cannot be opened, they are kept in your browser's local storage. The newest 25 are kept. Microsoft hosts that storage as part of your organization; Microsoft's own privacy terms apply.

I do not run a server that receives or stores any of this.

Nothing. The extension makes no requests to LeDuc Systems servers. It has no analytics, tracking pixels or advertising. I do not sell data.
