If you’re looking for fully encrypted chat apps, then WhatsApp is one app to consider. Installed by more than one billion users, the app offers end-to-end encryption, which means that nobody can access your chats and calls history without having access to your device.
However, a security researcher discovered that WhatsApp doesn’t protect your privacy as good when it comes to deleted chats or chats that were backed up. While that sounds like a bad thing, meaning that anyone could theoretically access them (again, physical access to your device is still needed), you shouldn’t freak out about it just yet.
