A mobile game's privacy policy has to cover ground a typical app's policy doesn't. Games monetize through ad networks and in-app purchases far more heavily than the average utility or productivity app, which means more third-party SDKs collecting data, more payment information changing hands, and, if the game could plausibly appeal to kids, a specific federal law, COPPA, that treats children's data with far more restriction than GDPR or CCPA do on their own. A policy copied from a generic app template usually misses all three.
Ad SDK data: the part most game policies underexplain
Free-to-play games are typically supported by ad networks (AdMob, Meta Audience Network, AppLovin, Unity Ads, and similar), and each one bundled into the build collects its own data independently of anything the game's own code does. That commonly includes the advertising identifier (IDFA on iOS, the Google Advertising ID on Android), device information, approximate location, and behavioral data used to decide which ad to serve and to measure whether it worked.
This matters for the policy in two ways. First, every ad network vendor actually integrated needs to be named, not summarized as "advertising partners," because both app stores require the same specificity in their disclosure forms, and mismatches between form and policy are one of the more common causes of review delays. Second, whether ads are personalized (using identifiers to target based on behavior) or contextual (targeted only by content, no cross-app tracking) changes what has to be disclosed and, for a game that could appeal to children, which is legally allowed at all.
In-app purchase data: a second, separate data flow
IAP data is a distinct collection stream from gameplay or ad data, and it's easy to underweight in a policy written mostly with ads in mind. Depending on the store's payment flow, a game may see purchase history, transaction identifiers, subscription status, and, if using a payment processor directly rather than the store's own billing system, more detailed payment information. The policy needs to say who processes payments (the App Store, Google Play, or a third-party processor), what purchase-related data the game itself retains versus what the platform handles entirely, and how a player can request a refund or dispute a charge, since both major stores have specific mechanisms here that a game's own policy should point to rather than duplicate incorrectly.
Randomized item mechanics come with their own disclosure rules
A lot of free-to-play games sell randomized virtual items, loot boxes, gacha pulls, mystery crates, where the player pays for a chance at an outcome rather than a guaranteed item. This isn't strictly a privacy issue, but it's close enough to the same compliance surface that it belongs in the same review pass: both major app stores now require disclosing the odds of receiving each item type before purchase, as a store review requirement rather than a privacy law. Some jurisdictions go further and regulate this directly, South Korea's Game Industry Promotion Act and Belgium's gambling authority have both taken enforcement positions on undisclosed loot box odds, and China requires published probability disclosures for randomized items sold in games available there. None of this belongs inside the privacy policy itself, odds disclosure is normally handled in-store or in a dedicated in-game screen, but a game that sells randomized items and hasn't checked whether its target markets require odds disclosure is carrying a second, separate compliance gap alongside anything the privacy policy covers.
COPPA: the question every game has to answer, not just kids' games
The Children's Online Privacy Protection Act applies to any app, including a game, that's either directed at children under 13 or has actual knowledge that it's collecting personal information from users under 13. A game doesn't have to be explicitly marketed as a kids' game to trigger this: bright, simple art style, gameplay mechanics common in children's games, or a rating that skews young are all factors both the FTC and the app stores weigh when deciding whether a game counts as child-directed, even if the developer didn't intend it that way.
Child-directed vs mixed-audience or general-audience game
| Child-directed (COPPA) | General/mixed audience | |
|---|---|---|
| Verifiable parental consent required before data collection | ||
| Personalized/behavioral advertising allowed | ||
| Persistent identifiers (ad ID) collection allowed | Only with consent, limited uses | |
| Store-level API restrictions apply | Certified child-directed ad SDKs only | Standard ad SDK rules |
| Contextual, non-tracking ads still allowed |
If a game is child-directed, both Google Play (through its Families Policy and the Play Families ad SDK requirements) and Apple (through App Store review guidelines for the Kids Category) require using ad SDKs certified for child-directed treatment, which serve only contextual, non-personalized ads and don't collect persistent identifiers for tracking. A general or mixed-audience game that simply might have some younger players doesn't carry the same verifiable-parental-consent requirement, but it does need age-screening logic and settings that route any user who identifies as under 13 into a restricted, non-personalized-ad experience, since "we didn't know" is a weaker defense than an actual age gate.
What the policy itself needs to say
Pulling the pieces together, a mobile game's privacy policy should cover:
- Every ad network SDK bundled in the build, named specifically, and whether it serves personalized or contextual ads.
- What in-app purchase and payment data is collected, who processes it, and how refunds or disputes work.
- Whether the game is child-directed, and if it is, that verifiable parental consent is obtained before any data collection begins and that no behavioral advertising or persistent-identifier tracking occurs.
- For a mixed-audience game, the age-screening mechanism and what changes for a user who identifies as under 13.
- Standard data-subject rights language, GDPR and CCPA both apply to game studios with EU or California players the same way they apply to any other business, layered on top of the COPPA-specific sections rather than replacing them.
- How a player can request account or data deletion, matching both stores' current expectations for an accessible in-app path, not just an email address.
Keep the store forms and the policy in sync as the game updates
A live game changes constantly, a new ad mediation partner added for fill rate, a new IAP bundle, an event that temporarily adds a new SDK. Each of those changes the data map this policy is built on, and both App Store Connect's Privacy Nutrition Label and Google Play's Data Safety section need to move in step with it. Treat "update privacy policy and store disclosures" as part of the same release checklist that already covers version bumps and store screenshots, the same discipline any mobile app needs, just with a wider SDK and payment surface for a game specifically.
Our Privacy Policy Generator builds a policy around the ad networks, IAP setup, and child-directed status you tell it about, so the sections on advertising, payments, and COPPA compliance match what your build actually does, ready to link from both stores' disclosure forms. For the general mobile app version of this same process, see How to Write a Privacy Policy for a Mobile App; for a broader look at how a policy differs by distribution platform, How to Write a Privacy Policy for a Shopify Store covers the same underlying idea for ecommerce instead of gaming.
