The U.S. Federal Trade Commission issued a record-setting fine in a settlement with Musical.ly on Wednesday, alleging the social media platform violated the Children’s Online Privacy Protection Act.

The $5.7 million penalty is the largest the FTC has issued over COPPA violations. Musical.ly, also known as TikTok, is alleged to have collected children’s personal data without parental consent. An email address, phone number, full name, username, a profile picture and a short bio are required to sign up for Musical.ly’s app.
