Location inference is a way for computers to figure out where you are. It's like when your parents ask you where you are, but the computer is asking your device (like a computer, phone, or tablet) where it is. The computer can do this by looking at data from satellites or cell phone towers or by using the built-in GPS system (Global Positioning System) in your device. This way the computer knows exactly where you are, even if you don't tell it.
