Hi, Protonmail is a great service, but protecting your emails is still not enough to guarantee privacy. Considering that Google openly admits it is capitalizing on all the data stored in our Android devices, and that Apple or BlackBerry simply do not communicate on the data that they collect, protecting our privacy will require more than encrypted emails. A new smartphone software company focused on software has been launched by former Nokia employees: Jolla (http://jolla.com/). It is focused on data privacy, and wishes to become an alternative to Android. It has already shipped a smartphone and a tablet. How about a Protonmail app for Jolla? The OS is compatible with Android apps, so porting should be easy. Regards.
