{mosads}The Children’s Online Privacy Protection Act (COPPA) restricts websites from knowingly collecting information from children younger than 13 years of age. The FTC’s revision, scheduled to take effect on July 1, expands the regulations to cover games, apps and ad networks.

App developers have asked the FTC to delay the implementation of the rules until Jan. 1, 2014, saying they need more time to ensure their products are in compliance.

But the privacy groups argue that companies have had plenty of time to adjust their privacy policies since the FTC announced the new rules in December. Although the FTC has yet to issue a “Frequently Asked Questions” document, it has already provided an advisory and other guidance to businesses on how to comply with the rules, the groups said.

“The revisions to COPPA are necessary to protect children and assist parents in light of the growing use of computers, mobile phones, and tablets, the increasing amount of data that is collected through these devices, and the sophisticated methods used to target and market to consumers,” the groups wrote.
