The data page most apps hide. I'm putting mine up front.
Your child is under 9, so the law (COPPA) makes you the boss of their data. Here's exactly how that works here — in plain words.
Nobody outside your family is in your child's world
Build together as a family — you and up to three kids in one shared world. Still family-only: the only people who can ever join are you and your own kids — no strangers, no public servers, no friend lists, no chat with anyone outside your family. Siblings build side by side, each as themselves — their own name, their own colour.
What I collect: almost nothing
No name, no email or photo for your child, no location, no contacts, no microphone, no biometrics. You sign in (Google or Apple); each child — up to three — plays as a profile under your one account, never a separate login a stranger could find. Even in family co-op, you're still the single credentialed account, so the only people who can ever join are you and your own kids — no outside logins.
How consent works
You're the only login, and you pay with a card — a method COPPA recognizes for confirming a real adult is giving permission. So the same payment that funds the build also helps confirm it's really you.
What I never do
- No ads, ever.
- No third-party trackers in the game your child plays — check the network tab while they play. (This marketing website uses basic, privacy-respecting analytics to count visits; it never touches your child or their game.)
- I never sell or share your child's data.
- Puzzle answers are graded on my server and never sent to the device — so they can't be peeked at on the page. (That's about integrity, not collecting more from your kid.)
Your controls
From the grown-up menu you can download all your data with one tap, or choose Delete account: we re-check it's really you, you type to confirm, and your whole family's data is erased right away — fully gone within 24 hours, with no undo. Consent records are kept apart from your child's world saves, and data is encrypted in transit and at rest. Read our full data-retention policy →
Don't take my word for it
Open your browser's network tab while your kid plays. You'll see zero trackers in the game — that's the point. (These marketing pages use basic analytics to count visits, but the game itself stays clean.)
Built around COPPA from day one — and a privacy lawyer has reviewed it. It's the one part I refused to wing.
