About Copy-Control System (User Authentication)

About Copy-Control System(from May 25th, 2011)

DLsite offers an optional copy-control system for your products.

It helps prevent illegal distribution of your work on the web. However, it does not guarantee absolute protection against such acts; it only ensures your products not to be copied easily.

The copy-control system has some limitations to the file format and to the browsing environment.
Please make sure of the following limitations.

How to add copy-control to your products

DLsite will perform the implementation.
The only thing you need to do is to check the box for the copy protection when you submit a product.

The copy-control for your products is offered for free.

How it works

When you view a product, your login ID and password will be requested. You can view the products only when your purchase at DLsite is confirmed through the authentication. The product is viewable only on the PC or the smartphone on which you authenticated the purchase.

Except for the game, you need to install special software/app according to its category to browse the product.

Notice

  • The copy-control system becomes of no value if your products are available in other shops with no relevant copy-control system.
  • You cannot add the copy-control option to your products after its release on DLsite.
  • The use of free anti-virus software such as avast!, AVG ANTIVIR and COMODO may prevent you from viewing the product normally.
