San Diego sues AppLovin over children's data

San Diego County has sued AppLovin, alleging the mobile ad giant bypassed parental controls to collect data from children's devices and served ads for adult dating services, alcohol, vaping products and sexually explicit content inside games played by kids. The complaint alleges AppLovin used device fingerprinting to track children even when parental controls and ad-tracking opt-outs were enabled, per Bloomberg's coverage. AppLovin's own policies prohibit collecting children's data or knowingly serving ads to children. AdTechRadar notes this lands on a company already navigating a run of controversies, and it carries the market's read: AppLovin shares are down roughly 54% year to date. The site is careful about the individual allegations, noting some past controversies have been less convincing and that a U.S. Securities and Exchange Commission inquiry closed without an enforcement recommendation, but it argues the accumulation matters and that a suit involving sexual content served to children is hard to brush aside. AppLovin is also locked in litigation with Unity. The company's line, per AdTechRadar's summary of its response, is that "AppLovin very clearly doesn't serve these ads," with one defender arguing there is "just no point taking a few thousand or even million bucks and risking the whole business."

The crux

A mobile ad platform's fingerprinting is alleged to have defeated the exact parental controls designed to stop it, which puts the whole app-monetisation supply chain, not just AppLovin, inside the compliance perimeter that child-directed rules were meant to keep outside.

Sell-side read

Publishers and app owners who carry a mobile ad partner inherit its data practices in any regulatory action. Ask for the fingerprinting disclosure before the next renewal; a partner that cannot say it honours opt-outs is a liability line on your own balance sheet.

Watch

whether the county action forces a consent order that sets a fingerprinting precedent for the rest of mobile in-app inventory.
