**Please describe the nature of your copyright ownership or authorization to act on the owner's behalf.**

I am [private] for Devsisters Corp. and am authorized to act on its behalf in connection with the enforcement of its intellectual property rights.

Devsisters Corp. and its subsidiary company, Studio Kingdom are the owner of, or holds the relevant exclusive rights in, the copyrighted software and audiovisual materials comprising the video game titled “CookieRun:Classic,” including its game client software, source and object code, graphics, character artwork, animations, user-interface elements, text, audio, and other original game content.

**Please provide a detailed description of the original copyrighted work that has allegedly been infringed.**

The reported repository reproduces and distributes materials extracted, decompiled, reconstructed, or otherwise derived from the proprietary “CookieRun: Classic” game client. The repository includes extracted assets, decompiled scripts, initial SQLite DB and its JSON snapshots, reconstructed source files, proprietary data files, and downloadable archives containing those materials.

These materials contain original copyrighted expression belonging to Devsisters Corp. They were not released as open-source software, and neither the repository owner nor its contributors have been authorized to extract, reproduce, modify, publish, or distribute them.

Where relevant, the uploaded materials retain distinctive names, structures, strings, assets, creative elements, and other characteristics corresponding directly to the copyrighted materials contained in the official game client.

**If the original work referenced above is available online, please provide a URL.**

**We ask that a DMCA takedown notice list every specific file in the repository that is infringing, unless the entire contents of the repository are infringing on your copyright. Please clearly state that the entire repository is infringing, OR provide the specific files within the repository you would like removed.**

**Based on the above, I confirm that:**

**Do you claim to have any technological measures in place to control access to your copyrighted content? Please see our <a href="https://docs.github.com/articles/guide-to-submitting-a-dmca-takedown-notice#complaints-about-anti-circumvention-technology">Complaints about Anti-Circumvention Technology</a> if you are unsure.**

Yes

**What technological measures do you have in place and how do they effectively control access to your copyrighted material?**

We utilize proprietary file encryption (e.g., AES encryption) and custom archive formatting to restrict unauthorized access to our copyrighted game data files within the application package (APK/IPA). These measures ensure that the files cannot be accessed or extracted without authorization.

**How is the accused project designed to circumvent your technological protection measures?**

The reported repository provides tools specifically designed to bypass and decrypt these technological access controls without our consent.

**If you are reporting an allegedly infringing fork, please note that each fork is a distinct repository and <i>must be identified separately</i>. Please read more about <a href="https://docs.github.com/articles/dmca-takedown-policy#b-what-about-forks-or-whats-a-fork">forks.</a> As forks may often contain different material than in the parent repository, if you believe any of the repositories or files in the forks are infringing, please list each fork URL below:**

**Is the work licensed under an open source license?**

No

**What would be the best solution for the alleged infringement?**

Reported content must be removed

**Do you have the alleged infringer’s contact information? If so, please provide it.**

**I have a good faith belief that use of the copyrighted materials described above on the infringing web pages is not authorized by the copyright owner, or its agent, or the law.**

**I have taken <a href="https://www.lumendatabase.org/topics/22">fair use</a> into consideration.**

**I swear, under penalty of perjury, that the information in this notification is accurate and that I am the copyright owner, or am authorized to act on behalf of the owner, of an exclusive right that is allegedly infringed.**
