Delivery that does not leak
The fastest way to lose money on digital products is a download link that ends up in a Telegram group. NefyX stores your file privately and hands out access only to people whose payment was confirmed. Download access is generated on demand for the buyer's account, so a link forwarded to a stranger does not become a free copy of your work.
No system can stop a determined buyer from re-sharing a file they have legitimately downloaded, and it would be dishonest to say otherwise. What good delivery does is make casual leaking hard and keep the original file out of public reach.
