To deter piracy, as part of its normal operation, every Avensoft product writes its serial number in to an HTML comment field in web pages it generates and the X-Mailer header of the emails it sends. This mechanism does not reveal any private information. It leaves evidence of the use of a uniquely identifiable legal copy of an Avensoft product in all computers that have accessed it. It is virtually impossible to remove all these evidence.
