A purchase that does not expire and remains in your library indefinitely is known as what?

A purchase that does not expire and remains in your library indefinitely is referred to as a non-consumable purchase. This term is used to describe items that can be used repeatedly or continuously without any limitations on their usage over time.

In digital contexts, such as video games, software, or online services, a non-consumable purchase is one that you own permanently, meaning you can access it anytime without worrying about it expiring or being removed from your account. This contrasts with consumable purchases, which may provide temporary benefits or items that can only be used once, leading to a need for repurchase. Non-renewable purchases imply a one-time acquisition without future access, while auto-renewable purchases automatically renew after a specified period, often requiring a subscription model. Non-consumable purchases provide users with lasting value, ensuring their investment is preserved indefinitely.
