Private messaging? WhatsApp given lowest privacy rating by watchdog
The app is used by more than 600 million people, making it the world's most popular messaging application, and 2015 is the first year it has been included in the EFF's government data protection scorecard.
The watchdog gave WhatsApp just one out of five stars, saying the company did not follow accepted best practice, did not inform users about government demands for their data, and did not make public their policy on keeping data about their users.
