Effective date: September 16, 2026
Card Duel does not collect, store, transmit, or share any personal information. The game runs entirely on your device, has no account system, no advertising, no analytics, and no internet connection requirement.
This policy covers the iOS app Card Duel (bundle identifier com.card.duel.challenge), published by its developer. It applies to everyone who downloads and plays the app.
None. Card Duel does not ask you to create an account, does not request your name, email, location, contacts, camera, microphone, or any other personal data, and does not connect to the internet to send information anywhere. There are no third-party analytics, advertising, or crash-reporting tools embedded in the app.
To remember your progress between sessions, the app saves a small amount of data locally on your device using Apple's standard UserDefaults storage. This data never leaves your device and is never seen by us.
| Saved locally | Purpose |
|---|---|
| Win streak & high score | Shown on the home screen |
| Story Mode progress | Tracks which of the 35 levels you've cleared |
| Coin balance | Earned by playing, spent in the Shop |
| Unlocked patterns & loadout | Your chosen card back, table, and sky |
| Gameplay settings | Camera and toss sensitivity preferences |
Card Duel does not integrate any third-party SDKs — no advertising networks, no analytics platforms, no social login, and no in-app purchase processing. No data is shared with anyone because none is collected in the first place.
Card Duel does not collect personal information from any user, including children under 13. Because no data is gathered, stored on our servers, or shared, the app contains no mechanism that could expose a child's information to third parties.
Since gameplay data never leaves your device, there is no server-side transmission for us to secure. Your saved progress is protected by the same sandboxing and encryption Apple applies to every app's local storage on iOS.
Deleting the app from your device permanently removes all locally stored data described above — there is nothing further to request, since we hold no copy of it ourselves.
If this policy ever changes — for example, if a future update adds a new feature that uses data — we will revise this page and update the effective date above before that update is released.
