Licenses and credits
LycanZip
LycanZip is free software under the MIT license. You may use, copy, change and share it, including for commercial purposes, as long as the license text stays with it. It comes without warranty.
7-Zip
The packing and unpacking is done by the 7-Zip engine by Igor Pavlov, loaded as a separate library (7z.dll, bundled in the packages together with its license texts). 7-Zip is licensed under the GNU LGPL, and the code that reads RAR archives carries the “unRAR restriction”: it may be used to read RAR archives, but not to build software that creates RAR archives. LycanZip only extracts RAR archives. LycanZip is not made, endorsed or supported by the authors of 7-Zip.
Windows App SDK and WinUI 3
The interface uses the Windows App SDK and WinUI 3 by Microsoft (MIT license). “Windows”, “Microsoft Store” and the other product names on this site belong to their owners.
The full list
The complete list of the components and their licenses is in the file THIRD_PARTY.md and the licenses folder of every package, and in the source repository.
