This exercise saves only the invented marker HARBOR-27 in a first-party cookie and local storage for this website. It reads no other website, account or browsing history.
Open this same URL in another private window before closing every private window. Then reopen it in a new private session. The page reports what the browser returns; it cannot tell whether every private window is closed.
Download the harmless note. A downloaded file is separate from cookies and local storage. Keep the downloaded note, close the private session, then look for the saved file in your chosen folder.
