Not worth the stress.
Yes, a few of my kid's friends have this app- yes, it's the kids with 'hipster parents' who are never really home and are probably using it themselves.
But do some serious studying up on this, because it's just not safe. PHOTOS DO NOT DISAPPEAR. They can be saved as 'screenshots'- so if there's even an experiment in 'sexting', that's all she wrote. ANYTHING INAPPROPRIATE will be seen by everyone at some point. And guess what? If your 15 boy is sent a sexually suggestive photo from a 15 year old girl, and the girls parents freak out- your boy has to register as a sex offender.
When you send a Snap to someone via "Snapchat" you give Snapchat a "nonexclusive, worldwide, royalty-free, sublicensable and transferable license to use, reproduce, modify, adapt, publish, create derivative works from, distribute, perform and display such user content in connection with the services, subject to your use of privacy settings in the services to control who can see your user content."
Read what VERIZON says about it here, and know that when a major company like Verizon says 'beware', they aren't messing around.
Not worth it.
