Unveiled at this year’s Mobile World Congress in Barcelona, Blackphone is a project aiming to offer consumers a secure Android phone coupled with a privacy-oriented mobile operating system called PrivatOS. On Tuesday, the company announced a new version of PrivatOS, as well as the launch of the Blackphone app store, which it says is the first privacy-focused app store. The most important new feature in PrivatOS is called Spaces, giving users the ability to create completely separate sandboxes in which they can have different apps and accounts.
