Data you enter in games

Names and items you enter in the Ladder Game, Spin Wheel, and Team Splitter and Draw are processed only in your current browser. They are not sent to a server or stored in cookies or localStorage, and no account is created.

Game scores

Best scores for the Memory Game, Number Baseball, Reaction Time Test, Minesweeper, Sliding Puzzle, Color Sense Test, Perfect Pitch Test, Sudoku, Stopwatch Stop, and Gomoku (time, moves, attempts, mistakes, average reaction time, level, correct answers, timing error, and wins and losses) are saved in the localStorage of your browser under greatjin.mini.memory.v1, greatjin.mini.baseball.v1, greatjin.mini.reaction.v1, greatjin.mini.minesweeper.v1, greatjin.mini.sliding.v1, greatjin.mini.color.v1, greatjin.mini.pitch.v1, greatjin.mini.sudoku.v1, greatjin.mini.stopwatch.v1, and greatjin.mini.omok.v1. Number Baseball and Sudoku also save your daily progress under greatjin.mini.baseball.today.v1 and greatjin.mini.sudoku.today.v1 so you can continue after reloading. Daily scores are kept for the last 14 days only. Scores are never sent to a server or synced to other devices. Clear the site data in your browser to delete them.

Share links

So the same screen can be reopened, the Ladder Game, Spin Wheel, and Team Splitter and Draw put the names, items, and draw number you enter in the part of the address after #. That part is not sent to the web server, but anyone you share the link with can read it. Links can remain in browser history or chat apps, so do not include real names or other sensitive information.
