Imagine a night puzzle selling a dark theme. A player buys it once and expects it in later sessions.
How: work toward a solution
A fictional night puzzle app begins with its night theme locked. Buy it once, then apply it repeatedly: ownership stays unlocked and the purchase count remains one. Repeat purchase attempts do not charge again here. Real purchase restoration is outside this local simulation. Prices, taxes, fees and refunds are omitted; reset clears only the example.
A purchased entitlement survives repeated use.

Applying never consumes ownership. Repeat purchase adds no charge. Real purchase restoration is outside this demo.
No real purchase. Prices, taxes, fees and refunds omitted.
The player buys the theme once; using it or pressing purchase again does not increase the purchase count beyond one. The theme stays available within this demo session. Price and actual store restoration are not modeled.
A fictional demo within this article. Reset or reload restores its initial state.
What: the concept
A non-consumable purchase unlocks an entitlement that does not expire or decrease through use. It differs from consumable units and recurring subscriptions.
Combine with free access and define restoration separately.
A night puzzle theme fits a lasting unlock because playing does not use up the theme. Consumable hints decrease with use; subscriptions depend on their access period. A non-consumable describes entitlement behavior, not every obligation associated with a one-time sale.
02Applications
The player buys the theme once; using it or pressing purchase again does not increase the purchase count beyond one. The theme stays available within this demo session. Price and actual store restoration are not modeled.
03Implementation & cautions
Production must verify transactions, support restoration and handle revocations. Reload resets this educational example, not the definition of a non-consumable. Account changes and refunds need explicit entitlement rules rather than browser-only storage.
