Google – My Activity
Find and see your search history, browsing history, and other activity that’s saved to your Google Account in My Activity. You’re in control of this data and can easily delete activity from your account.

It might also freak you out that that company knows that much about you… it even shows what apps you've last used and when. The My Activity page links to other pages showing the data Google has collected. You can see which sites you visit, what devices you used, which apps you’ve used, and which Google products you’ve interacted with. Each activity entry is placed on a timeline so you can scroll back through your history to see everything that Google knows you’ve been up to. The best feature… you can browse through and delete items. You can also delete everything in a specific date range or by particular topics.

In Google fashion you can search or filter through your activity. Think of it like your search history, but for everything you do online. You can filter results based on time, which Google products you were using, or keywords you specify. You can delete specific activities, delete entire topics from your history, or selectively disable certain types of tracking like location history or device information.

Maybe it's staggering that have so much info (though everyone in IT already knew that). However, you've got to hand it to them that they give you a way to disable tracking wholesale, or simply remove certain activities that you’d rather Google not know about.
