Unfortunately, we do not currently support Cloud Save in our game and therefore the ability to restore any progress should you delete Longleaf Valley or have installed it on another device, though we will be adding it to the future. 

If you have Longleaf Valley installed on a previous device you might be able to manually transfer your game data using one of the methods described here: How do I transfer my progress between two or more devices?

Apologies that we can't do more to help you remotely.
