Use of StampJar
StampJar is a family rewards tool for parents. You are responsible for the family data, child accounts, tasks, rewards, QR codes, and approvals you create in the app.
Parent and Child Accounts
Parents manage family data and child accounts. Do not share parent login credentials with children or untrusted adults.
QR Codes
QR codes are intended for trusted adults to submit pending stamps. StampJar matches each scan to the right child account and public task. A QR submission does not count toward a child's balance until a parent approves it. Rotate a QR code if it was shared too broadly or should stop working.
Rewards
Rewards are family-defined promises, not money, financial products, or allowance tracking. Parents are responsible for deciding whether a child has earned and redeemed a reward.
StampJar Plus Subscriptions
StampJar Plus is an optional parent-facing auto-renewable subscription that unlocks higher family limits and parent tools. Subscriptions are billed through your Apple ID and renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel subscriptions in your App Store account settings. Child accounts and public QR contributors cannot purchase StampJar Plus.
Availability
StampJar depends on Apple devices, StoreKit, Supabase services, internet connectivity, and Vercel-hosted public pages. Features may change as the app moves through TestFlight and App Store review.
No Warranty
StampJar is provided as is. Use it as a planning and family coordination tool, not as a safety-critical, legal, financial, or educational record system.
