What happens next
  1. Windows will show a blue warning — “Windows protected your PC.” That’s normal for new software from a small company: click More info, then Run anyway. GreenCube is safe — Windows just doesn’t know us yet.
  2. First launch downloads GreenCube’s AI brain — a few GB, one time only. Grab a coffee; the app shows progress the whole way.
  3. Sign in with the email you bought with — checked once, then GreenCube is yours and runs fully offline.

Activation happens inside the app. Open GreenCube and sign in with the same email you used at checkout — it verifies your purchase once, then runs fully offline.
