To do this, go to Home > Apps > Google> Menu > Settings. Then you can delete your history and activate or deactivate the feeds you desire. Where you’ll have access to what you have seen and interacted with recently.
From here, you can view descriptions of what was on each card. Click the items you want to delete, either individually or in blocks. You can choose what history to be deleted by the day, week, month, or entire history and renew your feeds.
The Feed setting turns the entire Google Now feature on and off. When selected, you can also choose to delete your Google Feed preferences and disable Google Feed. On all the devices tied to your account.
