# [Apple Family Sharing](https://developer.apple.com/app-store/subscriptions/#family-sharing)
## Introduction
Apple allows auto-renewable subscriptions and non-consumable in-app purchases to be shared within a family.
In order to use this feature, Family Sharing must be enabled on a per purchasable basis. See [Turn on Family Sharing for in-app purchases](https://help.apple.com/app-store-connect/#/dev45b03fab9).
### Is Family Shareable
The family shareable status of a product is available through the `isFamilyShareable` field found in the Apple product metadata.
The metadata can be obtained from `ProductMetadata.GetAppleProductMetadata()` via `IStoreController.products`.
````
bool IsProductFamilyShareable(Product product)
{
var appleProductMetadata = product.metadata.GetAppleProductMetadata();
return appleProductMetadata?.isFamilyShareable ?? false;
}
````
### Revoke Entitlement
In order to be handle revoked entitlements, you can specify a listener through the `IAppleConfiguration.SetEntitlementsRevokedListener(Action<List<Product>>`.
This will be called each time products have been revoked with the list of revoked products.
````
void InitializePurchasing()
{
var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
builder.Configure<IAppleConfiguration>().SetEntitlementsRevokedListener(EntitlementsRevokeListener);
UnityPurchasing.Initialize(this, builder);
}
void EntitlementsRevokeListener(List<Product> revokedProducts)
{
foreach (var revokedProduct in revokedProducts)
{
Debug.Log($"Revoked product: {revokedProduct.definition.id}");
}
}
