When your location on Facebook is on it means people will see where you are especially when you post. Facebook also made it possible for you to turn it off or on whenever you feel like, you only have to find out how to do it. I have compiled some steps you can use to achieve this.
How do I turn my location off
Go to your phone Settings.
Tap on Applications.
Scroll through the list of apps and tap on Facebook.
Tap on Permissions from the list of options.
Turn Location off.
For iPhone Users
Go to your iPhone Settings and tap on it.
Scroll down and tap on Privacy
Tap on Location Services and toggle the switch to ON or OFF.
