2017 - Telegram adds unsend feature to catch up with Viber


Messaging app Telegram adds “unsend” feature which lets users retrieve (i.e. delete) messages within two days of sending them. Secure messenger Signal also recently added an ephemeral messaging feature, back in October — albeit for ‘tidiness’, not privacy. Telegram’s unsend feature works within one-to-one and group messaging scenarios, and has to be enacted within the 48 hour window. It says the idea is to serve users with ‘morning after messaging regret’ by letting them scrub stuff they wish they’d never said.

2016 - Viber adds end-to-end encryption and hidden chats. Telegram is in panic


Following WhatsApp, another popular messaging app Viber is introducing end-to-end encryption for all messages and calls on its platform, including group chats (you can chat with up to 200 people), and a way to ‘hide’ chats on your account alongside its existing expanded deleting function. The new privacy features will work across Android, iOS, PCs and Mac desktops, with the encryption coming with the latest app update (6.0) and a reauthentication of the app (via QR Code) to turn the feature on. Viber’s encryption will come with varying levels of security, which will show up in the form of a color-coded lock on the right side of the screen.
