Content protection on Gumroad

Gumroad offers a variety of security measures to keep your content safe:

• All download links are unique
• Purchaser IP addresses are tracked and we ask for the buyer's email address if they attempt to access the link from a different location.
• Streaming-only for videos allows for a high level of protection because the file is never downloaded to the buyer's computer or device. The signed, expired, and tracked links for streaming prevent file sharing.
• PDF Stamping allows you to stamp your ebook or other written file (in PDF format) with a beautiful graphic of your buyer's email address, acting as a strong deterrent to widespread sharing.
