A lawsuit out of New Mexico accuses several tech companies of illegally monitoring the location and activity of children to sell that data to advertisers.

Filed in the U.S. District Court for the District of New Mexico by state Attorney General Hector Balderas, the lawsuit alleges that several apps “clearly and indisputably designed for children” made by Lithuanian company Tiny Lab Productions are collecting and exfiltrating user data to third parties to provide children-targeted advertisements without parental consent.
