Common Questions
Does the app need an account, subscription, or in-app purchase?
No. Deepvein is a one-time paid download. The full game is included and no account is required.
Does it work offline?
Yes. Gameplay and bundled content work on the device without a developer-operated service.
Where is progress stored?
Your mine state, upgrades, records, offline-progress timestamps, and settings remain in the app's local storage.
How do I remove local data?
Use an available reset or delete control. Removing the app removes its local container, subject to backups you control through Apple.
