If you don’t change your Snapchat privacy settings, Snapchat is not entirely safe. Features like location services and public photo sharing put you at risk of cyberstalking, cyberbullying, or online hacking.
Here’s how to adjust your security settings to be safer on Snapchat:
Go to your Settings.
Scroll to “Additional Services” then “Manage.”
Go to “Ad Preferences.”
Toggle off all options.
Next, go to “Who Can…” under Settings and limit who can interact with you or see your location on Snapchat.
