App data
Friends, expressions and the collection are saved in local JSON. Hinge and virtual-habitat inputs are processed locally. A still image leaves the device only when you choose a share destination.
Advertising
When production ad identifiers are configured, the free version may request and show a full-screen ad after the collection closes. You may also choose to watch a rewarded video for temporary access to Fern. Ads are withheld while purchase entitlement is unresolved or being checked, and for verified purchasers. If production ad identifiers are absent, ads are unavailable.
Before requesting ads, the app uses Google's User Messaging Platform to check consent and present a choice where required. It may ask for iOS tracking permission; denying tracking does not by itself prevent ads. When required, you can reopen privacy choices from the app's settings. Google Mobile Ads may process data such as IP address, device identifiers, ad views and interactions, and diagnostic or performance information for ad delivery and measurement, according to your choices and applicable settings. See Google's Mobile Ads data disclosure.
Purchases
StoreKit contacts Apple for products, purchases and restoration. The app uses verified purchase entitlements. The developer does not receive card numbers or payment details. Apple manages transaction records and refunds.
Storage and deletion
Manage local settings and records using the app's deletion controls or by removing the app. Keychain credentials, shared copies, device backups and provider records may require separate management.
Public pages and support
