Let's say that I use Chrome's incognito mode and search for a specific term using Google Image Search without being logged into my Google Account. After Google gives me the results, I click on a certain image and then click on "Show more related images". Then Google uses the chosen image as a filter for new related images, while still using the same search term.
My question is the following: does Google track this activity? I mean, does the choice of an image used as a filter stay get stored or only the search term?
