💡 feedback@happylittlesums.comCommon questions
What ages is it for?
Around 4–7, and it grows with your child. In the app you pick an age band (4 & under, 5–6, 7–9, 10+) and every game adjusts how big the numbers get. You can change it any time in Settings.
Does it work offline?
Yes — every game works fully offline once the app is installed. No connection is needed to play.
Do you collect data about my child?
No. There are no accounts, no analytics, no ads and no trackers. A few small settings (like the chosen age and collected stars) stay on the device and are never uploaded.
How do I change the app's language?
Happy Little Sums follows your phone's language (English, Dutch, Spanish, French, German, Italian or Portuguese). To use a different one, open the app's Settings, tap Language, and choose it — or select “System default” to follow your phone again.
How do I change my child's age level?
Open Settings in the app and tap Player age. Choosing a new age offers to reset the collected stars, so a new player can start fresh.
How do I manage or cancel my subscription?
Subscriptions are handled by Apple or Google. Manage or cancel any time in your App Store or Google Play account settings.
How do I restore my subscription on a new device?
Open the app, go to the subscription screen and tap Restore purchase while signed in with the same Apple ID or Google account.
