Unroll Me, the popular app that lets you “unroll” your email inbox to see all of your messages in one place, is coming under fire from privacy advocates. The app sells access to users’ email addresses and other personal information to third-party companies. Critics say this allows these companies to sell this data to marketers or other interested parties, potentially violating users’ privacy. Unroll Me says it only sells user data if a user agrees to do so in the app’s terms of service. But critics say these terms are often hidden or difficult to find, and that users may not realize they’re giving away their information until it’s too late. Unroll Me is one of the most popular apps on the market, with more than 50 million downloads. It has come under fire before for its privacy practices; last year, it was forced to change its policy after being sued by the Federal Trade Commission for violating consumer privacy rights. ..
