Plainly

Repairing is open. Taking the file is not.

Stated here the way the product states it: before you choose a document, not after you have fixed it.

You can rotate, delete, extract and reorder as much as you like and see the result. Downloading the repaired document is what the subscription covers.

Cancelling takes two clicks in the account. There is also a cancellation page that works without logging in, which is unusual enough to be worth mentioning.
