Mahjongpad keeps your results only in this browser on this device — nothing is uploaded, no account. Closing a private window or clearing browser data erases them, and they don't move to another device by themselves: save a backup file regularly.
Results & settlement ledger
After each hanchan, type three scores — the fourth fills itself. Uma, oka, chips, bust and game fees are worked out, with a running balance and your own stop-loss line.
Mahjongpad is a personal score and settlement notebook for your own games. It does not host games, take bets or move money. Every number is one you typed, and it never leaves this device.
