Is Chesscheat safe?

Chesscheat reads chess.com board positions and overlays Stockfish best-move highlights during games.

Chesscheat runs as a content script on chess.com pages and adds a control to start move assistance. When enabled, it reads the visible board pieces from the page DOM, converts them into a chess position, runs Chess.com's Stockfish worker in the browser, and draws highlight boxes for the returned best move.
