What we collect
Parent account: the email address you sign in with, and — once billing is live — your subscription status through Stripe (which plan, billed monthly or yearly). We never see or store your card number; Stripe handles that.
Players (your kids' profiles): a first name or nickname you type in, an optional avatar, and play statistics — which multiplication facts they've practiced, how quickly, and how accurately. We use these stats to schedule what to practice next; they're tied to an internal profile id, not shared or shown anywhere outside your account.
What we never do
- We never sell your family's data, to anyone, ever.
- We never show ads, in the app or alongside it.
- We never track you across other apps or websites — nothing here plugs into an ad network or a cross-site identity graph.
- We never require your child to create their own account, email address, or password. Players live under your account.
- We never record or watch a Player's screen while they play — session replay is turned off, everywhere, for every surface, unconditionally.
Analytics
We use PostHog, a first-party product-analytics tool, to understand which parts of Mastery Arcade help kids learn and which parts confuse them. Analytics events carry only your parent account id (never a child's name or photo) and gameplay facts like “a level was mastered” or “a question was answered correctly.” We route all of this data through our own servers first — we don't hand it to third-party ad or data brokers.
Payments
Arcade Pass subscriptions are processed by Stripe, a PCI-compliant payment processor used by millions of businesses. Your card details are entered directly with Stripe and never touch our servers. We store only what Stripe tells us about your subscription (active, plan, renewal date) so the app knows what you're entitled to play.
Data deletion
You can remove any Player's profile at any time from your Account hub — that deletes their play history immediately. To delete your entire account and every record we hold about your family, email us at support@masteryarcade.com and we'll confirm and complete the deletion within 30 days.
COPPA statement
Mastery Arcade accounts are created and owned by a parent or guardian — children never sign up on their own. We do not knowingly collect personal information directly from children beyond what a parent chooses to enter on their behalf (a nickname, an optional avatar). We do not knowingly allow a child to reach us outside the app (no chat, no forums, no messaging), and every subscribe/upgrade surface lives in the grown-ups areas of the app — never inside active gameplay.
