Popular video calling and messaging app JusTalk claims to be both secure and encrypted. But a security lapse has proven the app to be neither secure nor encrypted after a huge cache of users’ unencrypted private messages was found online.

The messaging app is widely used across Asia and has a booming international audience with 20 million users globally. Google Play lists JusTalk Kids, billed as its child-friendly and compatible version of its messaging app, as having more than 1 million Android downloads.
