Offline Chess 1.0 (build 1) — the first App Store release.
This release is the complete corresponding source for the App Store binary, published under the GNU General Public License version 3 or later. Offline Chess statically links Stockfish 18, so the combined work carries the same licence.

The two networks are not tracked in git — the larger one exceeds GitHub's hard 100 MiB per-file limit, and upstream Stockfish does not track them either. From a clone, restore them with ./Scripts/fetch_networks.sh, which downloads from these assets and verifies both digests.
