The changes announced Wednesday revise some of the policies governing Google's "Apps for Education" products.
Among other things, Google Inc. says it will no longer scan texts of Gmails sent through Apps for Education for clues about students' interests. The scanning would give the company a better idea about what kinds of ads to show them.
Google is also removing an option that allowed school administrators to show Gmail ads when students were using Apps for Education. The Mountain View, Calif., company had been automatically blocking the ads unless administrator changed the controls.
More than 30 million students, teachers and administrators use the Apps for Education suite.
