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.
SMS messaging
If you give us a mobile number and consent to messages, we use it only to send progress updates and practice reminders for your own account. Message frequency varies, up to 2 messages per week. Message and data rates may apply. Reply STOP to cancel or HELP for help.
Mobile information collected for SMS will never be shared or sold to third parties or lead generators for marketing or promotional purposes. Consent to SMS is never a condition of purchase or of using Mastery Arcade, and you can withdraw it at any time by replying STOP or from your notification settings.
We only ever message the adult who owns the account. We do not send messages to children.
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, open your Account page and use Delete account at the bottom. We ask you to confirm it's you and to type the word DELETE, and then it happens straight away — every Player, all their progress and trophies, any photos, and your account itself. If you have a paid Arcade Pass we cancel it at the same moment, so nothing is charged again. It cannot be undone and we cannot bring it back.
Prefer we do it for you? Email support@masteryarcade.com and we'll confirm and complete the deletion within 30 days.
How long we keep things
While your account is open: we keep a Player's progress for as long as that Player exists, because the whole point is to remember what they have learned. Account and billing records are kept while the account is active.
When you delete a Player: their progress and any avatar are deleted immediately.
When you delete your account: deleting it yourself from the Account page removes everything immediately — every Player, all their progress and trophies, photos, and the account record. If you ask us to do it by email instead, we complete it within 30 days. Either way the only things we keep are records we are legally required to keep — payment records, which tax law requires us to retain for seven years, and records of your consent to text messages, which we keep for three years as telecoms rules require. Those are held by our payment processor and by us in isolation, and are not used for anything else.
If an account goes quiet: after three years with no sign-in we delete the account and everything in it, after emailing you first. We do not keep children's data indefinitely on the chance somebody comes back.
You never have to wait for any of this — delete a Player or the whole account whenever you like, from your Account page or by emailing us.
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.
