# DECLARATION As stated on [CodeCombat's legal page](https://codecombat.com/legal), CodeCombat Inc. reserves all rights to the Levels, which are not open source, not made publicly available, and not permissible to use on other servers. This has been true since the beginning, when CodeCombat's code was [first uploaded to GitHub on January 3, 2014](https://github.com/codecombat/codecombat/blob/6009df26de7c7938c0af2122ffba72c07123d172/app/templates/legal.jade#L71-L84). The only authorized CodeCombat servers are operated by CodeCombat at [codecombat.com](https://codecombat.com/) and by our official China partner, NetEase, at [codecombat.163.com](https://codecombat.163.com/). We can't abide flagrant pirate servers. We believe in open source. As such, we encourage open source collaborators to make use of CodeCombat's work on our code and art assets. CodeCombat's website code is licensed under the [MIT license](http://opensource.org/licenses/MIT), and the art, sounds, and music are licensed under [the Creative Commons 4.0 International License](https://creativecommons.org/licenses/by/4.0/). But we've spent tens of thousands of hours developing CodeCombat's levels–they're how we support our business. It has always been clear that if you want to run your own public CodeCombat server, you have to make your own levels instead of scraping CodeCombat's. (You should also change the branding, addresses, team and legal pages, and other configuration on any public CodeCombat server you operate, and attribute the Creative Commons assets.) CodeCombat Inc. # 声明 如美国 [CodeCombat 官网法律声明页面](https://codecombat.com/legal)所述，关卡的所有权利由美国 CodeCombat 公司保留。这些关卡的代码并不是开源的，不能被公开使用，也不允许在其它服务器上被使用。[从 2014 年 1 月 3 日美国 CodeCombat 的代码首次上传到 GitHub 以来](https://github.com/codecombat/codecombat/blob/6009df26de7c7938c0af2122ffba72c07123d172/app/templates/legal.jade#L71-L84)，均是如此。在中国地区，唯一获得美国 CodeCombat 公司授权的是我们在中国的官方合作伙伴网易，域名为 [codecombat.163.com](https://codecombat.163.com/)（极客战记）。我们不能允许侵权的盗版服务器的存在。 我们信任开源。因此，我们鼓励开源协作者使用美国CodeCombat 的代码和素材。虽然美国 CodeCombat 的网站代码是遵守 [MIT 协议授权许可](http://opensource.org/licenses/MIT)的，产品涉及的美术、音效、音乐素材是遵循 [Creative Commons 4.0 国际协议授权许可](https://creativecommons.org/licenses/by/4.0/)的。但是，我们花了数万小时去开发美国CodeCombat 的关卡，而这些关卡是支撑美国CodeCombat业务的基础。一直以来很明确的是，如果你想要运营自己的公开 CodeCombat 服务器，就必须自己创建关卡，而不是盗用美国 CodeCombat 已有的关卡。（同时， 你还需要更改所运营的任何公开美国 CodeCombat 服务器上的品牌，地址，团队和法律声明等信息，以及其他配置，并对 Creative Commons 资产做出署名。） 美国 CodeCombat 公司
