There is a tool called the Location History Visualizer that uses Google data to create a heat map of all the places you have ever been. Google knows everything about your travels and daily commute unless you changed your location history settings. Todd Haselton for CNBC wrote that Google knew when he arrived at his office down to the exact minute as well as storing a copy of photos he took at each location he visited. Even when you are not using Google Maps or another Google app the information is gathered and stored. This personal map is only visible to you but if you are uncomfortable with the concept of your whereabouts being digitised, there’s a way to disable Google’s location tracking feature.
Go to Google’s Privacy Checkup page, scroll to Location History and select Manage Location History. Next, scroll to the bottom of the page and select Manage Location History once again and then toggle the button to turn tracking off. You can also delete past data by clicking Delete all location history under settings on the Location History map. But wait—that’s not the final step: You’ll also need to visit your Google Activity Controls and turn Web & Activity off. After that, you’ll finally be off the grid.
Just keep in mind that “some Google apps may not work the same as they did before,” according to Google. The company uses location data to offer real-time traffic updates, personalised maps, and recommendations based on the places you’ve been.
