Today, one of the most popular encrypted chat apps, Viber (which is owned by Rakuten Inc.) rolled out what it calls “secret messages,” to give users even more control over their communications. Over the last few years, more and more of these messaging apps began to offer end-to-end encryption to win over users who want privacy at least as much as they want to gab candidly with friends. Messaging apps can amass a lot of user data over time including everything from personal photos and videos users have shared to records of who they talk to most, where they’ve been, and what online financial services they use.
