Your kid's favorite apps might be sharing sensitive info

NEW YORK (FOX 5 NEWS) - Most parents have probably heard of apps like Snapchat and Instagram. But while you may think you're in the know with social media, your child is probably on to an entirely new trending app.

Video messaging apps are wildly popular amongst teens and tweens. House Party is a virtual chat room for kids to "hang out." Marco Polo calls itself a video walkie-talkie.

Divamoms.com CEO Lyss Stern, a parenting expert, says managing your child's use of social media is crucial because of the dangers that come along with it.

Apps like a Yellow enable your child to swipe right to find other friends. While the minimum age is 13, there is no way to monitor who is on the other side of a photo. Stern says it is like "Tinder for teens and tweens" and that is frightening.

What is more frightening is that the app opens with a geo-locator, so anyone on it can see where your child is. Even Snapchat has location settings you might not be aware of.

Stern says parents need to control the settings on their child's phone and make sure location services are turned off.

And another point of warning with the apps: just because you can't see something doesn't mean it wasn't there. Like Snapchat and Instagram stories, most of the content on these new apps easily disappears, so harassment and bullying is hard to find. But your kids are often dealing with it.
