Where do you disable Google Timeline on the Android phone?
Go to Settings, then Location.
Find Google Location Settings and individually switch off both Location Reporting and Location History.
Underneath Location History, select “Delete Location History” to wipe clean the cache of locations.
Repeat the steps for every Google account you have registered.


Note that disabling all location-finding features will throw a monkey wrench into the functioning of some  apps, so it’s wise to carefully consider which you want to strip of location services
