In fact, usually these ad and tracking networks are not even aware that Incognito mode is used. This remote data collection does not stop when the browser is in Incognito mode.
And this kind of data collection is also independent from the browser you use, although some browsers have special features or some extensions can be added to reduce the amount of tracking and profiling. This is similar how other companies like Facebook or the various ad and tracking networks are included into the websites. Google is instead a company which among others things collects information about the users behavior by being included with Google Analytics or Doubleclick into many websites.
The point here is locally stored because this is all the browser can fully control.
I think you need to distinguish between 'Google' and 'Chrome'.Ĭhrome is a browser and the main feature of the Incognito mode is to delete any locally stored information from the browser session after the Incognito mode was closed.
