The one-time purchase that unlocks full access is processed through Google Play. Refunds are handled exclusively through Google Play under Google’s refund policy — Lormalibu Labs cannot issue refunds itself. If a purchase you already made is not showing as unlocked in the app, try "Restore purchase" in the full-access area first.
