Please be aware that strangers can potentially contact your child using Snapchat and other social media apps. 
To make sure your child is safe on Snapchat, please check their settings.
Snapchat’s privacy settings are important to understand. The default “My Friends” setting only allows users to send and receive media from users they have added to their friends list. It is highly recommended that any minor using Snapchat continues to use this setting. For more help with this, visit https://support.snapchat.com/a/privacy-settings
Please note: Snapchat has a minimum age requirement of 13 years old.
