Family Sharing lets a whole family use one subscription, and you cannot undo it.

What does Apple document about turning Family Sharing on?

The page that governs this is short. App Store Connect Help opens by saying Family Sharing is a feature supported only by apps that offer auto renewable subscriptions and non consumable In-App Purchases, and that it enables users to share their purchases with up to five additional family members. Further down, in the box that describes the switch itself, Apple writes that the subscription will be able to be shared by up to six family members. Both sentences are on the same page. Five extra people plus the purchaser makes six, so the arithmetic holds, but if you are writing a paywall line or answering a support email, quote the sentence rather than the bare number.

The path is in the help page and it is quick. In Apps, select the app. In the sidebar under Monetization, click In-App Purchases, or Subscriptions and then the subscription group. Pick the product, scroll down to the Family Sharing section, click Turn On, then read the Family Sharing terms in the confirmation dialog and click Confirm. The required role is Account Holder or App Manager, so a Marketing or Finance user cannot do it for you. Apple adds one timing note: it may take up to 1 hour for changes you make to product metadata to appear in the sandbox environment, which is worth knowing before you decide the setting did not save.

Who ends up with access depends on more than your switch. Apple says whether a user's purchases are automatically shared depends on the type of In-App Purchase, the user's sharing preferences, and whether the purchase was made before or after you turned Family Sharing on in App Store Connect. For subscriptions, sharing is on by default for new subscribers according to the preference they set in Manage Subscriptions, while anyone who subscribed earlier has to opt in from their manage subscriptions page. For non consumables, four separate settings have to line up, including the app not being hidden from the purchaser's purchase history. One more trap sits next to it: if multiseat purchases are on, only the group purchaser is eligible for Family Sharing, and the additional seats are for individual use only.

Can you turn Family Sharing off again?

No, and Apple says it twice. The help page: keep in mind that once you turn on Family Sharing for an In-App Purchase in App Store Connect, you can't turn it off. The StoreKit article, Supporting Family Sharing in your app, repeats it almost word for word. The multiseat section of the help page says it a third time, in passing. For a setting with that many warnings attached it is striking how little ceremony the interface gives it: a section, a button marked Turn On, and one dialog.

Customers have the flexibility you do not. The same help page says users have the option of turning off Family Sharing in their subscription settings at any time. So a reader who has turned sharing off is not a reader with a broken app, and a support reply that says the feature cannot be disabled is wrong from their side of the screen. If you need a product nobody can share, the only route left is a new product, a new product ID, and a migration for anybody already on the old one.

Your app has to handle access going away, because it will. Apple lists three causes in the StoreKit article: the purchaser leaves the group, the purchaser gets a refund, or the purchaser stops sharing. The expectation is that the family's access stops immediately. StoreKit tells you by calling paymentQueue(_:didRevokeEntitlementsForProductIdentifiers:) on your transaction observer, and a server running App Store Server Notifications gets a REVOKE notification. Revoked products show up in the receipt with a cancellation_date field present. That observer method is the one piece of real work Family Sharing adds, since Apple is clear that shared purchases otherwise go through your normal purchase handling.

What does Family Sharing do to your revenue?

It does nothing you can see in a payment, and that is the honest answer. The App Store Connect Help page for the switch runs to a few thousand characters of article text and contains no occurrence of revenue, proceeds, price, commission, charge or refund. I checked the words on 21 October 2026. Apple's StoreKit article is the only one of the two that mentions money at all, and it frames the case as a possibility rather than a promise: enabling Family Sharing can make your content or service more appealing to subscribers, and may encourage conversion to a paid subscription, increase customer engagement, and improve retention. One subscription stays one subscription. Up to five more people get access to it, and nobody pays you for them.

Where you will see it is in your reports, and the field is easy to misread. App Store Connect Help describes the Subscribers field in the Subscription Report as the number of subscribers who have access to the auto renewable subscription including entitled family members. The same reference says the field is only populated when the record represents more than 3 subscriptions. So the count answers a different question from your proceeds: it tells you how many people can use the thing, not how many people bought it. Divide money by that number and your average revenue per subscriber falls for reasons that have nothing to do with what you charge or which of the app store pricing tiers you picked.

Nothing about this setting changes your commercial terms. Your cut and the rules for collecting it come from the app store paid apps agreement you signed, and the withholding on what you are paid comes from your app store tax forms. Family Sharing moves none of that. Treat it as a pricing decision instead: a family of four paying once is either four people you would never have won individually, or one subscription where you might have sold two. Which one it is depends on your product, and the switch does not let you test and find out.

Does Google Play have an equivalent for subscriptions?

No. Google's nearest thing is Google Play Family Library, and its help page is specific about what it covers: you can share purchased apps, games, movies, TV shows, and e-books and audiobooks with up to 5 family members. The same page then rules out the part you care about. You can't share in-app purchases and apps downloaded at no charge with your family members. The word subscription does not appear in the article at all, which I checked against the page body rather than a summary on 21 October 2026.

I read the developer side too, in case the feature lived there. The Play Billing page About subscriptions runs past fifty thousand characters and covers renewals, grace periods, replacement modes, prepaid plans, deep links into the subscriptions centre and cancellation handling. It never mentions family sharing. The only occurrences of the string family in that page are font declarations in its own stylesheet. So the absence is not a gap in my reading: there is no developer control to find.

Google clearly has the plumbing, because it uses it for itself. The Google Play Pass help page says that with a family library you can share a Google Play Pass subscription with your Google Play family group, and that when the family manager cancels, every family member loses access at the end of the billing period. Play Pass is Google's own subscription. Nothing on the Family Library page offers the same deal to yours.

There is one developer lever on Family Library, and it is about apps rather than purchases. Google says any apps or games purchased after July 2, 2016 are eligible to be added to Family Library, and that an app bought before that date is eligible only if the developer has made past purchases available. For a new app that sentence is history. The practical read for a 2026 launch: your paid app can be shared, anything bought inside it cannot, and your Android pricing has to stand on its own. If you are still adding up the cost to publish an app on both stores, this is one of the places the two platforms stop resembling each other.
