Facebook wants to add kids under 13 years of age to its 2 billion users.
The social network announced a new stand-alone app geared to them called Messenger Kids.
Pre-teens can use the app to chat with their friends, make calls with kid-friendly filters and send age-appropriate images.
Parents must set up accounts for their children and approve who they can communicate with.
Facebook promises it will collect little data about messenger kids users and will not allow them to make purchases.
The rules for traditional Facebook services aren't changing -- kids still have to be 13 years old to get their own accounts.
A preview version of Messenger Kids rolled out Monday on Apple devices.
Android and Kindle versions are coming later.
Snapchat launched a similar service for kids under 13 several years ago called Snap Kidz.
It has been discontinued without explanation.
