Except where required by applicable law, Platform Provider policy, or a separate written policy specified by us, Paid Services and digital content are not refundable or cancellable after purchase confirmation, payment completion, subscription renewal, or provision of the relevant content or function.

7. If the Services provide points, coins, virtual items, or similar digital benefits, they have no cash value, cannot be transferred or exchanged outside the Services, and may expire or become unavailable when the applicable service ends, except where required by applicable law.
