This has nothing to do with my phone syncing with my home PC but when searching Google.com on Chrome for Android three of my previous searches appear in a drop down menu as soon as I click the search field. I've changed the privacy setting on my phone to "Pause" my activity/history/etc. and I've started clearing all the data, cookies, search history etc. via the Chrome menu and I even started using CCleaner (which is awesome overall, gets rid of stuff I didn't even know was there and frees up space on my phone whenever I use it) but none of this stops the previous searches drop down menu. I never asked Google to store everything I search for and it's annoying that this is happening even though I have nothing to hide because I know to use Incognito mode when necessary. How do I stop Google showing my past searches when I click the search field? Besides only browsing from Incognito mode that is.
Use the "Privacy Checkup" tool found at https://myaccount.google.com.
Specifically, under "Personalize your Google experience", you'll want to turn off (uncheck)
