📦How vaults work
TreeHouse is part app, part real-world. The app shows the numbers. Real cash sits in real jars at home. A sticker with a QR code keeps them in sync. No fake balances.

Soft flat illustration on cream background showing a circular flow. Top: a smartphone displaying a clean dashboard with a brand-green balance number. Right: an arrow curves down to a glass jar with stacked coins. Bottom: another arrow curves to a paper QR-code sticker being placed on the jar by a friendly hand. Left: an arrow loops back up to the phone, which now shows the same number. Tiny green sparkles along the arrows to show 'in sync'. Limited palette: cream, brand green #1f7a3f, soft pink, warm gold. Rounded shapes, thick 2px outlines, paper texture. QR codes drawn as simple geometric grids. No other text. 16:9 composition.
Step 1 — You earn cash
You finish a job. A parent gives you real coins or notes and taps "Pay" in the app. The app records it. Cash in your hand, number on the screen.
Step 2 — You drop cash into a vault jar
You decide: spend, save, grow, or give. You open the matching jar at home and physically put the cash in. Then you scan its QR sticker — the app moves the same amount into that vault in your dashboard.

Soft flat illustration. A kid (simple round face) holds a smartphone close to a glass jar on a wooden table. The phone screen shows a camera viewfinder with corner brackets aligning over a paper QR-code label on the jar. A faint green scanning beam glows between them. A small confirmation checkmark floats in the upper corner. Cream background, paper texture. Limited palette: cream, brand green, soft pink, light wood brown. Rounded shapes, thick outlines. QR drawn as simple geometric grid. No text. 3:2 composition.
Step 3 — Take it out
When you want to spend from a vault, you open the jar, take the cash, and scan the QR again. The dashboard updates. Simple. Honest.
