Frequently asked questions
How do I add another child?
On the home screen, tap the dashed + chip in the "Who's playing?" row and enter the child's name and age. Each child gets their own levels, scores, and progress in every game.
How do I switch between children?
Tap a child's chip in the "Who's playing?" row on the home screen. The highlighted chip is the active player.
How do I remove a child?
Touch and hold the child's chip and choose Remove player…. A parental gate (a grown-ups-only math question) protects this step. Removing a child permanently deletes their levels, stats, and progress from the device.
Is my child’s data safe?
Yes. The app collects nothing — no accounts, no ads, no tracking. Everything stays on your device. Read our privacy policy for details.
How do subscriptions work?
Full access is an auto-renewing subscription billed through your Apple Account. The current price and any free trial are shown in the app before you buy. A parental gate protects the purchase screen. Manage or cancel anytime in Settings → your name → Subscriptions. On a new device, open the purchase screen and tap Restore Purchases.
