The variables are not cleared. Every chain runs in a loop of its own, that is garbage collected as soon as the chain ends.
I think as chaley pointed out, it is better not to persist variables because you are going to run into scope problems.
However, the user has the option to persist some variables before exiting the chain. This can be done by creating and empty book and calling it something like 'persistent storage'. You can persist whatever data you want into this book, by using the selection modifier to select it, then the single field edit template option to persist.
