title: How to automatically save and load user input kivy
body: <p>I am making an app where there is a profile screen in which you can enter generic profile information (name, height, weight, ect..) using textinput boxes. I know there is a way to put a button next to each textinput box to save the information and another button to load the information. I am wondering if there is a way to automatically load this information when the user opens the app rather than manually loading the information by hitting a button.  Some have suggested ussing a subclass of ConfigParser to parse standard ini files and use this to load app-specific settings, but I have no idea how to do this.</p>
