In most cases, a site now must obtain parental consent before it collects, uses, or discloses personal information about a child under age 13. Note that parents may give consent but still say no to having information passed on to third parties. Sites must request consent again if they plan to use the information in a new way. Parents also may revoke consent at any time. Ask to see personal information collected from your kids.
Parents have a right to delete information collected from kids.
