When you turn off location history Google still tracks your location when you use several of its key services including Maps, search and the weather. Heres how to really turn all of it off.
A report from the Associated Press has highlighted that the feature called location history is just one of the systems that Google uses to track your location for personalised services, local search and other purposes such as advertising.
When you turn off location history, Google stops automatically recording your location for features such as the Maps timeline, but it warns you that some location data may be saved as part of your activity on other Google services, like Search and Maps. When you perform a search, access Google Maps, or get the weather, either manually or automatically through a smartphone widget, Google will still log your location.
To prevent it from doing so you need to turn off another setting called Web & App Activity.
