But the app’s reliance on Google’s predictive software drew immediate criticism from privacy advocates who argued it could open up user data to law enforcement — with former US intelligence contractor Edward Snowden warning people not to use it. Snowden, the former US intelligence contractor wanted for leaking National Security Agency documents on surveillance, said in a tweet, “Don’t use Allo.”
A later tweet from Snowden called Allo an “app that records every message you ever send and makes it available to police upon request.” Google defended its privacy stand, saying users can opt for a more secure “incognito” mode if they prefer.
Google takes on WhatsApp, brings Allo-smart messenger service
“We also provide the option to chat in Incognito mode, where messages are end-to-end encrypted and you can set a timer to automatically delete messages for your device and the person you’re chatting with’s device at a set time.”
The app includes Google Assistant, an artificial intelligence program which makes live suggestions as you chat.
“You no longer need to leave a conversation with friends just to grab an address, share your favorite YouTube video, or pick a dinner spot,” Google said in a blog post.
“Google Allo can help you make plans, find information, and express yourself more easily in chat. And the more you use it, the more it improves over time,” Google said.
The app will adjust according to whether its user’s style is usually an emoji or written response, for example.
Like rival apps, it has tools for personalizing chat messages including changing the size of emojis and a choice of stickers. Allo was unveiled by Google in May at the same time as Google Duo, an app for video calls, which hit the market last month.
Google faces a challenge in carving a place in a sector dominated by popular apps such as WhatsApp, which Facebook acquired for some $20 billion in 2014 and which counts more than a billion users. In July, Facebook said that users of its own Messenger application had also passed the one billion mark.
