Is Chess Bot safe?

Clean risk

Chess Bot sends derived Chess.com board positions to stockfish.online for engine evaluation.

When you use Chess Bot on Chess.com, its content script reads the move list from the page and converts the game state into a FEN board position. It sends that position, along with the configured analysis depth, to stockfish.online so the service can return engine evaluation data.
