Easy File Shelf provides a space into which you can drag files, from Finder; and from which you can drag files, into Finder. No information about these files is transmitted by Easy File Shelf to myself or any other party. When stored in Easy File Shelf, the files are stored in the Easy File Shelf application container, which by default, at the time of writing this policy, is at ~/Library/Application Support/Containers/EasyFileShelf. The files are not transmitted by Easy File Shelf to myself, or to any other party.
