Why: the goal or problem

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.

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.
