It says on your website, "The only way to access your product is through the secure download link sent out to the buyer after a successful payment. This download link will expire after number of hours and/or number of downloads
specified by you."
Is this download link unique to each purchase? If so can I set a download limit of 1, and then each person will only be able to download it once? Or is this the same link for all people? If that is the case, surely people could just tell the link to their friends, etc and they could download without paying?
