Disclaimer

These guidelines do not grant a copyright license to any DDLC-related fan content. Despite these guidelines, Team Salvato reserves the right to issue a formal takedown request for any content that infringes copyright. This includes content that uses official DDLC assets, as well as content that includes any Intellectual Properties (IPs) that belong to Team Salvato. Moreover, this page is subject to revision at any time without notice.

Fan Work

“Fan Work” refers to any content that includes IPs that belong to Team Salvato. The content in question includes, but is not limited to, art, music, animation, writing, videos, websites, apps, and games. The guidelines pertain to any fan work that takes place in the DDLC universe or includes characters, setting, or storyline from DDLC.

Fan work may freely be produced and shared online. Fan work may NOT be sold online or otherwise distributed for profit.

There are no restrictions on how artists choose to depict the characters, setting, or events of DDLC in their fan work. We value artistic freedom and will not target fan work solely because we disagree with the content, or because it conflicts with official depictions.

Physical versions of fan work may be sold locally, in limited production, by independent artists (eg. at conventions).

Businesses or companies interested in producing DDLC fan work for sale by any means other than locally in limited production should contact us for licensing or permission.

Fan Work That Includes Official DDLC Assets

Some artists choose to include assets created by Team Salvato in their fan work. These assets include, but are not limited to, any art, music, writing, or code that was included in the DDLC game or DDLC-related marketing/promotional material.

Examples of fan work in this category include games, websites, videos, or music that include DDLC assets in them.

Any fan work that includes official DDLC assets may NOT be sold under any circumstances, online or offline. No profit may be made from these fan works in any way, except for fan work that constitutes as Fair Use under the United States FAIR USE Act of 2007. For example, a gameplay review video or commentary video typically qualifies as Fair Use. It is the artist’s responsibility to understand Fair Use and design qualifying content.

Direct upload or hosting of DDLC assets is forbidden, except when to be used as part of fan work. No profit may be made from these uploads.

Fan Games

“Fan Games” refer to any fan work that is a game. This also includes new games that contain no official DDLC assets, as well as mods of the official DDLC game.

You may NOT create, copy, or distribute any fan game that is designed to be played in lieu of the official DDLC game. Any fan games, including mods, that “replace” DDLC, or imply that it should be played before the original, are forbidden. This includes mods that add new content to the DDLC base game, including, but not limited to, new art, new scenes, new visual effects, or voice acting. Fan games may ONLY be created with the assumption that the player has already completed the original DDLC game, and is looking for fan content.

A common example is fan games that let players spend more time with the club members, possibly including new story arcs, or to satisfy the players’ desire for additional dialogue, or for a more “normal” game. These games are usually considered okay, because the only players interested in them would be those who have completed DDLC and are looking for new content. Any fan games or mods that suggest new players should play it instead of DDLC are not allowed.

Fan games must state upon first run that it is a fan game unaffiliated with the official Doki Doki Literature Club. They must advise that the original game should be completed before playing, as well as provide a link to the official website where it can be downloaded (http://ddlc.moe).

Below is an example disclaimer for your convenience:

This is a Doki Doki Literature Club fan game that is not affiliated with Team Salvato. It is designed to be played only after the official game has been completed. You can download Doki Doki Literature Club at: http://ddlc.moe

Mods

The above guidelines regarding fan games also apply to mods of the official DDLC game. A mod is any game or project whose content relies on making changes to the official DDLC game, such as adding/replacing code, art, music, writing, or other assets.

Any mods must NOT be distributed as a complete game. They should contain only the files that are necessary to install the mod (usually files that are added to the DDLC game folder). Most mods only require the scripts.rpa file to be replaced – sometimes images.rpa if new graphics have been added to the game. In this example, please distribute your mod ONLY as these files, so that the user installs it into their existing official DDLC game.

Everything Else

These guidelines are not necessarily exhaustive. If you wish to work on anything DDLC-related that is not covered here, or you are unsure of the specifics, then please contact us for clarification. Furthermore, please contact us if you would like to request a personal exception or a change in the guidelines, or to report a mistake on this page.

Thank you for taking the time to understand the IP Guidelines. We chose to publish these guidelines not to restrict artists, but to express our desire to allow them to produce DDLC-related content. We wish to encourage artistic freedom and hope to see fans enjoy DDLC in many different ways.
