Appearance

Theme Dark or light overall colour scheme. Board squares and accent colour stay the same in both.
Board coordinates Show file letters and rank numbers on the board.
Rounded board edges Soften the outer corners of every board in the app. Off keeps the crisp squared look.
Language Interface language. Chess analysis prose stays in English for now.

Board & Pieces

Colour palette Accent colour for buttons, links, and the active-page indicator. Independent of the board theme.
Board theme Seasonal colour palette for the chessboard squares. Default is the standard slate / stone look.
Last-move highlight Colour of the squares marking the last move played, on every board (live play and review). Default is a faint yellow.
Piece set Style used for all chess pieces on every board.

Sounds

Enable sounds Move clicks, captures, checks, game start/end.
Volume Master volume for all sound effects.

Engine & Library

In-browser Stockfish Use the bundled WASM engine for in-game hints (instant, no network). Server engine is used as a fallback.
Auto-sync on launch Pull new chess.com games every time the app loads. Off by default so cold-start stays fast.

Motion

Piece animation How quickly pieces slide between squares.
Autoplay speed Speed of move-by-move autoplay in the review.
