How do I fix this problem?

So if I add new name to my list then show on the list, but if i exit from the app, and start the app, and then I see the listthen the list is clear, but if i spend some time in the app and show again the list, then will be visible the infos what I added before. Can you help me how fix this? Thank you!

Look at the local storage plugin I think. It lets you save stuff so it can be accessed from one run of the game to the next.
