Privacy & attribution

A short note on what we store, what we don’t, and who we credit.

Privacy

Chessility has no accounts and does not ask for your name, email, or other personal details.
Progress (wins, unlocked levels, and a short local game history) is stored only in your browser via localStorage. Clearing site data resets that progress.
Games stay on your device. We do not upload PGN, FEN, or move history to our servers.
If the app is hosted on Vercel, anonymous usage analytics may be collected by Vercel Analytics. That includes page views and a few in-app actions (play, rematch, beat streak). We do not send PGN, FEN, or move lists.

This demo stands on open tools and community assets:

Stockfish — chess engine (GPL-3.0)
chess.js — move generation and PGN/FEN handling
Piece sets include CBurnett (via Lichess / Wikipedia commons) and other public piece styles bundled with the project
UI built with Next.js, React, Tailwind CSS, and DaisyUI

Questions or corrections welcome via the project maintainer.
