"If a kid asks their parent to add all of their classmates who are also using Messenger Kids, for example, the app could become just another way for kids to bully or gang up on one another".
Parents are concerned by Facebook's new app for kids under 13.
When it comes to ads, Facebook said it will also not use data from Messenger Kids for Facebook ads.
The social media giant has started a trial of Messenger Kids, a version of its popular messaging app which will be only used by kids.
Messenger Kids comes here with a swing and slew of the controls for their parents.
Parents have to use their Facebook email address and password to activate their child's account, but that does not log a parent into their child's device. They may do so using their own standard Messenger app.
Federal law prohibits Internet companies from collecting personal information on kids who are below 13 without their parents' permission; as well the feature imposes restrictions on advertising to them.
Ms Cheng said: 'Parents are increasingly allowing their children to use tablets and smartphones, but often have questions and concerns about how their kids use them and which apps are appropriate.
Facebook Messenger suffered a similar outage on November 30 when users reported being unable to send messages. Through the app kids can still message their friends and family members but under parental control. Balkam also stated that the millions of kids under 13 are already on Facebook, with or without their parents' approval. Davis said that if a parent decides to delete a child's account, Facebook will also delete any data from its own servers.
Facebook CEO and co-founder Mark Zuckerberg, who is spending December on parental leave with his two daughters, hasn't spoken publicly yet about Messenger Kids. Facebook's safeguards have made it more hard for strangers to contact a child, they said. As a matter of fact, your kiddo won't even see any ads while using it because the developers at Facebook pledged Messenger Kids is an "ad-free experience", meaning they won't use their info to try to sell them anything (unlike the adult accounts, which are peppered with ads for things you may have considered buying at one point six months ago). According to a release, Facebook plans to release the app on other platforms such as the Amazon App Store, and the Google Play Store.
