## SumSum Kids Description
SumSum is a gentle math companion for children in K2 and Primary 1 in Singapore. It draws from the Ministry of Education mathematics framework for these levels, so the quests feel like play but line up with what kids are learning in school.

Three warm, unhurried quests:

• Count to 20 — recognise and count numbers using a ten-frame
• Number Bonds to 10 — the Singapore MOE foundation, visualised
• Add & Subtract within 20 — short, friendly practice with paired ten-frames

Designed for little hands and short attention spans:

• Big buttons, large numerals, rounded typography
• Cheerful audio and haptic confirmation on each correct tap
• Star rewards — no streaks, no timers, no pressure
• A parental gate (a simple math problem) guards any grown-up settings

Privacy by default:

• No accounts, no sign-ups
• No ads, no in-app purchases
• No tracking, no analytics
• Fully offline — nothing ever leaves the device
• Progress is stored on the device only

Built for a daughter. Shared with every kid learning to love numbers.
