An Android app with more than 10 million downloads left users' selfies, pictures, audio messages, and other sensitive data exposed online for all to see. The app, called Drupe, was once named a "Google Play Editor's Choice."

Drupe promises users to help them "forget" about traditional phonebook apps, allowing them to get in touch with their contacts all in one place with calls, text messages, audio messages and integrating with other popular apps like WhatsApp, Skype and Hangouts, among others. The Next Web called it "a cleverly designed dialer every Android user should try." Google featured Drupe in a recently deleted (but archived) post on the Android Developers website, praising the developers and awarding it a "Google Play's Editor's Choice."
