This permanently deletes your account () and everything stored with it: your cloud notebooks, lines and games, drill and puzzle progress, streaks, your public profile and photo, follows, messages, games shared with coaches, class codes and any notes you left as a coach. Games you shared with a coach disappear from their view too.
This cannot be undone. Notebooks you downloaded stay on your device; nothing else does.

The rating your moves in this game looked like. Not a rating change, not tied to the result.
Opening theory, forced moves and already-decided positions are not scored. Throwing away a won game is.
The percentage is accuracy: how close every move came to the computer’s best.
The computer marks each move as you step through a game — the symbol lands on the move and on the board.
