Most people don’t even know that they are constantly being tracked and that all their locations are being recorded in Google servers. Google states that your location history map is private and visible only to you, but it's nice to know that I can delete portions of my location history or all of it, as well as disable the feature from tracking me in the future.
There are many applications that use Google Location, so your movement is constantly being tracked. Even though it has many benefits most of us are uncomfortable due to privacy issues.
If you are uncomfortable you can disable OR clean history of your location.
Since it is not recommended to disable as many of our applications uses location services for example: banking apps, whatsapp etc.
You can set a 30 days time period to clear your past history.
How to delete past history?
Simply go to Google Maps ---> Settings---> Delete all location History
(All your past location history will be cleared)
