Snapchat’s Family Center is a decent first step, but it only shows you who they’re friends with, not what they’re saying. For true peace of mind, you need to see the content.
Pro tip: Parentaler can run in stealth mode on their iPhone. It lets you view their Snapchat messages, including the disappearing ones, without them knowing. This way, you can respect their privacy but still be alerted to any real danger like cyberbullying. It’s about intervening only when necessary.
