COPPA Child Data Violations Lawsuit

Lieff Cabraser and Co-Counsel File Class Action Lawsuit Alleging “Subway Surfers” App Violates Child Online Privacy Protection Laws

Parents in California and New York have filed a class action lawsuit on behalf of themselves and their children alleging that the popular mobile app game Subway Surfers violates privacy protection laws by exporting their children’s personal information to advertising networks without obtaining required parental consent.

The suit is brought against the two Danish companies, Kiloo ApS and Sybo ApS, that developed Subways Surfers, a game directed to children under 13 years of age, which, with more than a billion downloads, is one of the most played games worldwide.

The suit also alleges that certain other Kiloo or Sybo game apps also violate privacy laws. The other games referenced in the complaint are Frisbee Forever, Frisbee Forever 2, Spellbinders, Smash Champs, Tesla Tubes, Storm Blades, and Blades of Brim.

Also named as defendants in the suit are the companies that embedded software in Subway Surfers to collect and export the children’s personal information. These defendant ad tech companies are AdColony, Chartboost, Flurry, Inc. and Altaba Inc., InMobi Inc. and InMobi Pte. Ltd, Ironsource Ltd. and Ironsource USA, Inc., Tapjoy, Inc. and Vungle, Inc. Plaintiffs allege that Kiloo and Sybo allowed ad tech companies to embed their tracking software into their gaming apps to collect, use, and disclose their children’s personal data in order to target them with advertisements.

What is COPPA?

In 1999, Congress enacted the Children’s Online Privacy Protection Act (“COPPA”) to protect the safety and privacy of children online, and the autonomy of their parents, by providing parents the means to halt developers and third-party advertisers from snooping on and profiting from their children.

Many parents do not know that countless web and smartphone apps, including those created for children, are engineered to unlawfully exploit and commercialize underage users’ activity through hidden tracking technologies. As alleged in the complaint, these technologies unlawfully and surreptitiously collect and send data, including the users’ personal information, from the mobile device or tablet to third-parties. App developers and other third-parties then reap millions of dollars in profit from this personal information through lucrative targeted advertising.

The parents of the minor children brought the lawsuit seeking an injunction to force the defendants to cease tracking the personal information of children without obtaining parental consent and to bring defendants in compliance with the principles of COPPA and as required by state law. The parents also seek damages as may be permitted under some state laws.
