We developed our own proprietary operating system (Mudita OS) and chose the open-source, real-time operating system kernel FreeRTOS®️ as our starting point. Mudita OS gets digitally signed updates to make sure no one can alter it, which is a unique feature for a classic phone.
There is no camera and no Internet browser. The Pure does not use GPS or support any 3rd-party apps. The user can be tracked by their carrier (calling and texting), which is the case for all mobile phones. No other tracking is possible with the Pure.
Bluetooth if off by default and needs to be activated by the user. It also turns off automatically when it's not used for 10 minutes.
When it comes to texting, we have no encryption - we are using the SMS standard which does not support encryption.
The only link between your data and the outside world is the Mudita Center desktop app (for MacOS, Linux and Windows), which enables you to synchronize your data with your computer. Mudita Center can only connect to the internet to receive secure digitally-signed updates of the operating system. Its other purpose is synchronizing your data, adding audio, using selected Mudita OS tools on your laptop/desktop machine. We assure you that we do our best to secure our operating system and desktop app.
