The short version
Grammar Kingdom is a browser game for children. Players sign in with a Google account so their progress is saved and synced. We don't run ads, and we don't sell data. Payments are handled entirely by our payment provider.
Accounts and progress data
The game requires a Google account to sign in. This account holds the player's game progress: completed levels, best scores, stars, coins, streaks, achievements and practice data. Progress syncs to the player's account, so it follows them across phones, tablets and computers.
Because players sign in through Google, the usual Google account controls (such as account management and data removal) apply to the account itself.
The progress report
The game includes a progress report for parents and teachers. It is built from the player's own game data — per-topic accuracy, streaks and a 30-day activity trend — and is visible to the signed-in player and to classes they join.
Payments
Unlocking the Full Kingdom is a one-time purchase handled through the payment provider (Stripe Checkout). Payment details are entered on the provider's secure page and handled entirely by the provider — they never reach the game. Class access is managed with join codes and can be revoked when a class is disbanded or a member is removed.
