New Mexico Attorney General Hector Balderas recently filed another lawsuit against Google over data collection on students through its free Chromebook program and G Suite for Education platform.

The lawsuit alleges Google uses its free Chromebook program to illegally gather data on students, such as physical locations, web and search histories, YouTube views, contact lists, passwords, and recordings, according to The Verge.

The lawsuit, filed in late February, also contends Google has used the information to fuel advertising until April 2014, and it stores the data in personalized profiles that are unavailable to parents to view or limit. The lawsuit alleges the data collection was not properly disclosed to parents, and violates a federal and state laws.

“Student safety should be the number one priority of any company providing services to our children, particularly in schools,” Balderas said. “Tracking student data without parental consent is not only illegal, it is dangerous; and my office will hold any company accountable who compromises the safety of New Mexican children.”

The lawsuit is one of several Balderas has filed against the company for violating child privacy laws, including a broader antitrust probe involving the state attorneys general of all 50 states. The U.S. Department of Justice and Federal Trade Commission are pursuing similar efforts, according to The Verge.

The secret data collection practices “do not simply violate federal law, nor do they merely impact children under the age of 13,” the new lawsuit read. “Covertly monitoring children of all ages, despite unambiguous representations to the contrary, violates longstanding rights rooted in the common law as well as New Mexico’s statutory prohibitions on unfair, deceptive, and unconscionable business practice.”

Google disputed those claims in a statement to The Verge.

“G Suite for Education allows schools to control account access and requires that schools obtain parental consent when necessary,” spokesman Jose Castaneda wrote. “We do not use personal information from users in primary and secondary schools to target ads. School districts can decide how best to use Google for Education in their classrooms and we are committed to partnering with them.”

The Electronic Frontier Foundation last week launched a new Surveillance Self-Defense Guide for students and their parents to educate families on how schools are tracking kids online and at school, and what they can do about it.

The tracking currently includes software to scan social media posts, facial recognition cameras, microphones to “detect aggression” and other means.

“Schools can even track you on devices that they don’t control: if you have to download a certain kind of security certificate to use the school Internet, they may be monitoring your browser history and messages you send,” EFF reports.

“Some administrators argue that they need to use this technology to keep schools safe, yet there is little evidence that it works,” EFF Activism Project Manager Lindsay Oliver said. “Instead, surveillance can make people second-guess everything they do or say. When we are constantly spied on, we censor the way we express ourselves. That’s known as the ‘chilling effect.’ Students need space to experiment and learn without being monitored and recorded by their schools at every turn.”
