How to delete my Progress

So how you see in my title...How can i delete my progress?

I've been hacking since i buyed the game and now i want to be a legit player.

Well, its kinda impossible.

Use cloudextract to get your save.file.
Then:
1:Remove everything manually with Cloud Editor
or
2:Somwhere on this forum you can find a clean save file wich you can replace with your own save file
