Wormbound stores story progress, language, sound preferences and purchase access locally on the device. The game has no game account, developer gameplay server, advertising or behavioral analytics. Gameplay does not require camera, microphone, contacts or location access.
On iPhone and iPad, purchases and restoration use Apple's StoreKit. BooksWhale does not upload the game's saves or receipts to a developer server. Apple's store and payment services operate under Apple's privacy terms.
On Android, purchases and restoration use Google Play Billing. Google's billing component can send purchase-service interactions, technical diagnostics and billing-instance or transaction identifiers to Google, including billing results, app and operating-system versions, device model and build, network information, language and regional settings. These records support operation, technical analysis and reliability of the purchase service. The billing component does not expose an in-game switch to disable its diagnostic reporting. These records are distinct from story progress and are not used by BooksWhale for advertising. When you choose to buy or restore, Google Play processes purchase and entitlement information to provide access and protect the transaction under Google's privacy terms.
Payment-card details are entered in the platform's purchase interface, not in Wormbound. Clearing app data or uninstalling can remove local progress and preferences; an eligible store purchase can be restored through the same store account. BooksWhale cannot delete records held independently by Apple or Google. Platform privacy and account controls govern those records. The game itself has no account to delete.
