EarnPlay is a private, on-device motivation engine and effort gate for elementary-school children. A child takes on short math and reading challenges, and genuine effort, not perfect answers, earns timed access to apps a parent has chosen. Deterministic code holds every safety-critical decision; AI proposes, code decides. No account, no server, no child data leaves the device. The tutor is the challenge mechanism, not the purpose.
