The Children's Online Privacy Protection Act, known as COPPA, is a federal law designed in part to protect children under 13 years old on websites designed for kids, but a recent study found that just because a children’s app is certified complaint, it may not be any better than apps that are non-certified. The study, published in the journal Proceedings on Privacy Enhancing Technologies, states that because app certification may not guarantee security, parents should research apps their children are using and make sure they understand if and/or where personal data is stored or whether the information is being traded. It is also important to research what information the app can access from the device on which it is downloaded.
