Privacy Policy

Duels for iOS & Apple Watch · Last updated 29 May 2026

Duels is a single-player and local-multiplayer game. It is built to be played without an account, and it keeps your data on your device by default. This policy explains exactly what is — and is not — handled when you play.

The short version. No account or sign-up. No ads. No advertising identifiers and no third-party tracking. We never sell your data. The only information that ever leaves your device is anonymous, opt-out usage and crash statistics — and you can turn that off in Settings.

1Who we are

Duels is developed and published by 0n1 Studios, a sole proprietorship ("we", "us"). For any privacy question, contact [email protected].

2No account required

Duels has no login or user accounts. You are not asked for a name, email address, phone number, or any other contact detail. Your player profile — your progress, elements, inventory, and settings — is stored only on your device.

3What we collect

Duels can share anonymous usage and diagnostic statistics to help us fix bugs and improve the game. This is optional and can be disabled at any time under Settings → Share Anonymous Analytics. When enabled, the data is processed through TelemetryDeck and Apple's MetricKit and is not linked to your identity and is never used to track you across apps or services.

Data	When	Why	Linked to you
App usage & product interaction (e.g. tutorial completed, duel finished)	Only if analytics is on	Understand which features are used	No
Crash & performance diagnostics	Only if analytics is on	Find and fix stability issues	No
Purchase events (which bundle was bought)	Only if analytics is on	Understand what players value	No
Name, email, contacts, photos, precise location	Never collected	—	—
Advertising identifiers (IDFA)	Never collected	—	—

4In-app purchases

Duels offers optional in-app purchases. Payments are handled entirely by Apple through the App Store using your Apple ID. We do not see or store your payment card details. A record of what you have purchased is kept on your device so your items stay unlocked.

5Multiplayer duels

When you duel another player nearby, Duels connects the two devices directly over the local network or Bluetooth using Apple's MultipeerConnectivity framework. Game messages travel directly between the devices taking part — there is no Duels game server, and your gameplay is not routed through or stored on our infrastructure.

6Apple Watch

The Apple Watch companion mirrors live game state from your iPhone using Apple's WatchConnectivity. This information stays on your paired devices.

7Permissions we may request

Each permission is requested only when the relevant feature is used, and the game remains playable if you decline:

Motion & Fitness — reads device motion so you can cast spells with gestures. A "Tap to Cast" alternative is available in Settings if you prefer not to grant it.
Local Network — discovers nearby players for local multiplayer duels.
Camera — optional augmented-reality casting effects. Camera frames are used only to render the effect on-device and are not recorded or transmitted.
Location (When In Use) — optional, reserved for a future in-city map feature. It is not used to track you and your location is not transmitted to us.

8Where your data lives

Your profile and progress are stored locally on your device (in the iOS Keychain). Anonymous analytics, if enabled, are processed by TelemetryDeck. In-app purchase records are handled by Apple. Deleting the app removes the game's local data from your device.

9Children

Duels is not directed to children under 13, and we do not knowingly collect personal information from children. Because no personal information is collected to begin with, the game can be enjoyed without sharing any identifying details.

10Changes to this policy

If our data practices change, we will update this page and revise the date above. Significant changes will be reflected in a future app update.
