Numberville — maths for kids
Arithmetic practice for ages 5–9, wrapped in a house-building game. No ads, no accounts, fully offline.
Built deliberately narrow on the privacy side: no ads, no accounts, no data collection, and it works entirely offline. A parent zone shows progress and which tables have been mastered. Free to play, with a one-off Deluxe upgrade for extra rooms and furniture.
