Yes, I am the copyright holder.

**Are you submitting a revised DMCA notice after GitHub Trust & Safety requested you make changes to your original notice?**

No

**Does your claim involve content on GitHub or npm.js?**

GitHub

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

I am [private], the [private] of Backdrop and an authorized representative of Cindori AB. Cindori AB owns the copyright in the proprietary Backdrop macOS application and its original program code. I am authorized to submit this notice on Cindori AB’s behalf.

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

The copyrighted work is Backdrop for macOS, version 2.6.15 build 119, a proprietary commercial computer program developed and published by Cindori AB.

The protected work includes Cindori AB’s original source and compiled object code, original program structure and implementation, and original strings and software components implementing Backdrop’s catalog, wallpaper playback, playlists, user profiles, licensing, settings, cloud communication, and XPC wallpaper services.

The reported repository states that its contents were generated by reverse engineering Backdrop’s compiled ARM64 Mach-O executable. It publishes decompiler-generated pseudocode, disassembly, resolved original strings, and reconstructed program logic derived directly from that executable without Cindori AB’s authorization.

This claim is limited to original program code and expression owned by Cindori AB. It does not claim ownership of Apple frameworks, separately licensed third-party components, generic API names, functional ideas, or methods of operation.

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

https://cindori.com/backdrop

**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:**

Specific files within the repository are infringing

**Identify only the specific file URLs within the repository that is infringing:**

The following files contain decompiler-generated pseudocode and disassembly derived directly from Cindori AB’s proprietary Backdrop executable. They reproduce Cindori AB-owned application functions, control flow, original string constants, and program implementation without authorization:
