Now don´t panic, you can decide how much data Google will save. Here is what you have to do:
1. Click on this link and check the box on the lower left to see if your location feature is activated or not.
2. In case it is activated, click on the button to switch it off.
3. By deactivating the feature you do not automatically delete the saved data. To get rid of it delete your location history in the Settings tab.
4. Now click on Manage Activity. This will show you all of the locations you have been to in the past month. By adjusting the setting you can decide which time period from the location history should be erased.
Google is tracking your every move and there’s a website that proves it!
