💡 feedback@happylittlesums.comCommon questions
What ages is it for?
Around 4–7, and it grows with your child. Each game has four levels — you choose a level when you open a game, and it adjusts how big the numbers get. Different games can be on different levels, and you can change a game's level any time by reopening it.
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 (UK or US), Dutch, Spanish, French, German, Italian, or Portuguese (Portugal or Brazil). 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 a game's level?
Open the game from the game list and pick a level (1–4) on the level screen. Each game remembers its own last level. To change it mid-play, go back to the game list and open the game again.
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.
