Terms of Use
The service
Grammar Kingdom is a browser-based grammar practice game for children, played at grammarkingdom.my. This promotional website describes the game and links to it.
Accounts
Playing requires signing in with a Google account. Keep sign-in credentials safe, and don't share accounts between households. Class access works through join codes created by a teacher or group leader.
Purchases and access
The first world is free to play. The Full Kingdom — every world, plus future updates — is unlocked with a one-time payment, not a subscription. Purchases are processed by our payment provider (Stripe Checkout) on the provider's secure page.
- The Student Plan unlocks the Full Kingdom for one learner.
- The Teacher Plan unlocks the Full Kingdom and lets the purchaser share access with a whole class through a join code.
- Access can also be granted through unlock codes provided to schools and classes.
Premium access is verified against the purchase and can be revoked if an order is refunded, a class is disbanded, or a member is removed.
Fair use
Don't disrupt the service, attempt to bypass access controls or payment, or resell access to the game. Content in the game is provided for personal and classroom learning.
Availability
The game is provided "as is". We work to keep it available and correct, but features, content and availability may change over time.
