Digital Citizenship Internet Safety

I have Facebook and I was unaware my phone number was on there. I deleted it and double checked that my settings were set to only my friends can see my profile. I see there is also an option that only friends of friends can find you and send a friend request which is a great option. I also explored Snapchat and one thing I would to do is hide my location I don't like that anyone on your snapchat can see right where you are.
