Mudita Pure enables internet connection only when updating its firmware (FOTA) or when it’s necessary for the audio call to be carried over the LTE network (what has become a standard with most mobile operators - VoLTE). However, the phone is vulnerable to GSM network-related attacks in the same way as any other mobile phone.
The only link between your data and the outside world is the Mudita Center desktop app which enables you to synchronize your data with your laptop or desktop machine. Our desktop app can only connect to the internet to receive secure digitally-signed updates of the operating system or enable internet tethering. Its other purpose is synchronizing your data, adding audio, using selected MuditaOS tools on your laptop/desktop machine. We assure you that we do our best to secure our operating system and desktop app.
