Shoshana Wodinsky writes: “A new report published May 4 by the tech-focused nonprofit Me2B Alliance found the majority of school utility apps were sharing some amount of student data with third-party marketing companies. The Me2B team surveyed a few dozen so-called utility apps for school districts—the kind that students and parents download to, say, review their school’s calendar or busing schedules—and found roughly 60% of them sharing everything from a student’s location to their entire contact list, to their phone’s mobile ad identifiers, all with companies these students and their parents likely never heard of.”
