Third-party material
Some puzzle collections and the optional external solver are third-party material and are not owned by Sam Cornwell. They remain subject to their own terms. The BOXXY proprietary licence does not override those rights.
Your custom puzzles
You retain whatever rights you have in original puzzles you create. Using the BOXXY Level Maker does not transfer ownership of those puzzles to Sam Cornwell, and it does not grant rights in BOXXY itself.
Local storage and sharing
Progress and Level Maker material are stored in your browser. Shared-puzzle links contain an encoded puzzle layout and are unlisted rather than encrypted. The optional solver loads files from third-party hosting services.
