Apple has cracked down on apps in the App Store for violating user privacy. In previous news, Apple removed a handful of parental control apps, and now it has removed some dating apps.

Allegedly, Apple removed at least three dating apps from the Apple Store that were giving access to kids as young as 12 years old. The removed apps are Meet24, FastMeet, and Meet4U. The company that developed these dating apps is a Ukraine-based LLC called Wildec. The company denies any knowledge of underage use.

Whether the company knew or not, these dating apps violated the Children’s Online Privacy Protection Act (COPPA) which calls for their immediate removal and penalization.

Under COPPA, children under 13 years old are protected from any application gathering their personal information. Apps are required to deny access to children 13 years or younger and monitor and block any underage users.

According to the Federal Trade Commission (FTC), these apps are removed at least until and unless they address these alleged violations.
