'Snapchat' has introduced a new tracker in the latest update of the app where you can view the EXACT location of your friends if you pinch the screen inwards while in selfie mode. It shows the area, town, street and if you zoom in enough, it shows the house on the street layout.
Although legally the minimum age is 13, we are aware that there are a number of children who frequently use 'Snapchat'. If your child uses the app, please check that their location is set to 'ghost mode', that way no-one can see where they are.
To do this, ensure the app has been updated then go to 'selfie mode' on the camera, zoom out and it will give you the option of changing who can see your location.
