The only permission
needed for MatTalX to work properly is Storage. It is used to store your work in progress, if any.
The text written in the first box (input) right before closing MatTalX is saved, so that you can change tabs and continue the
text you started without having to start over. The settings, namely 'Adjust spaces', 'Mathematical font', and 'Math mode', are also saved.
MatTalX does NOT have access to your browser history, your open tabs, or any other private information.
