NORTH Yorkshire’s Safeguarding Children Board has issued safety advice to schools and parents following concerns over the social media function Snap Maps.

The new function released by social media app Snapchat - allows users to see where in the country other Snapchat contacts are.

It uses phones’ GPS sensors and users can zoom in to pinpoint the exact building other users are in, including their home or school.

The app is particularly popular among teenagers and has prompted safety warnings from charities and police forces following concerns it could be used for stalking or harassment.

It was installed as part of the app’s regular software updates, prompting concerns that many under-18s are unwittingly sharing their location.

Snapchat has defended the system, saying users have to opt in and it is helpful for finding friends when arranging to meet up.

North Yorkshire’s Safeguarding Children Board has now issued tips for children on location-sharing:

• Only share your location with people you know in person. Never share your location with strangers.

• Do not add contacts to Snapchat if you do not know them in person.

• Regularly review your settings and take an active decision about whether you want people to know your location. Remember, you can switch this off at any time.

• Think about where you are sharing your location. Location services such as Snap Maps can lead people to your house. Think about what times you are on the app and whether these are locations you want to share – if not, then turn this off within your settings.

North Yorkshire County Council’s executive member for children’s services, Councillor Janet Sanderson, said: “It is important to be careful about who you share your location with, as it can allow people to build up a picture of where you live, go to school and spend your time.

“Given how specific this new feature is on Snapchat - giving your location to a precise pinpoint on a map - we would encourage users not to share their location, especially with people they don’t know in person.’’

There are three settings for sharing location on the map:

• Ghost Mode - this means that you are the only person who can see your location on the map. You can still see the locations of your friends but they will be unable to see you. This setting will ensure that you have complete control over who knows your location.

• My Friends - this means that all of your contacts on Snapchat can see your location. If turning on this setting, then it would be important for users to review their Snapchat contacts and also make sure that they never add someone they do not know in person to Snapchat.

• Select Friends - this setting allows users to look through their friend list and then decide which of their friends they want to be able to view their location. This setting gives users the opportunity to control who can view their location.
