After reading this article, I signed into my account. I found that even though I turned off tracking in Google years ago, it still kept my old history.

The article says that Google turned on auto-delete for new accounts by default as the result of a lawsuit. However, if your Google account is older than x years, then they still keep all of your location history unless you go in and manually choose to delete it. Even then, I no longer trust that Google will actually delete it.
