@centrox,
Yeah... that isn't privacy. That just means the newspaper software is using cookies, rather than your IP.
Incognito mode does not ensure very much privacy. If you are trusting it, I strongly recommend you understand what it actually does...which isn't much.
Incognito mode doesn't prevent a website from seeing you ip or knowing your location. It doesn't stop people from tracking your search history or knowing what sites you visit.
