Local storage - saving/retrieving data in Edge Animate

I have a text field called "textfield" and I would like to save this information locally (it is a touch screen presentation) when pressing a button.

Also I´d like to be able to retrieve the information to the same text field after restarting the application.

I´ve read this is possible with Local storage. But how do I do this? (I´m mostly a designer, but can do a little bit of code).

Thanks!
