Terms of Service

Duo Fight support

Duo Fight brings disc football, mini curling, air hockey and disc knockout to one shared screen. Play locally with another person, practice against the computer, or try skill challenges.

Do I need an account or internet connection?

No account is required. Gameplay works offline on the same device; Duo Fight does not offer online multiplayer.

How do two players start?

Choose a game and select side-by-side or face-to-face seating. Each player presses their own readiness button. Use a sufficiently wide playing area for face-to-face games; on a foldable device, fully open the screen before starting.

Can I play on my own?

Choose solo practice against the computer or a skill challenge from the lobby.

Where are names and game progress stored?

Player labels, preferences, challenge progress and resumable match data are stored locally. There is no account-based cloud sync. Deleting the app can remove its local progress; offloading the app is different from deleting it. Apple device backups may include app data according to your system settings.

Does the app contain ads or in-app purchases?

The current version has no advertising, subscriptions or in-app purchases. The App Store listing shows any download price that applies.

1. Acceptance

By downloading, installing or using Duo Fight (the “App”), you agree to these Terms of Service. If you do not agree, do not use the App. Mandatory consumer rights under applicable law remain unaffected.

2. What Duo Fight does

The App provides local tabletop-style sports games for entertainment, including same-device two-player play, computer-opponent practice and skill challenges. Scores and game outcomes have no monetary value. The App does not provide betting or real-money prizes.

3. License and acceptable use

We grant you a personal, non-exclusive license to use the App in accordance with these Terms and the applicable Apple terms. You must not use it unlawfully, infringe another person's rights, redistribute the App without permission, disrupt its operation or bypass technical protections. Restrictions do not limit rights that applicable law expressly grants.

4. Local data and progress

You may enter optional player labels. Keep these appropriate and avoid sensitive personal information. Preferences and saved game progress remain on your device. Deleting the App, replacing data or device problems may cause progress to be lost. We do not provide an account-based recovery service.

5. Payments and refunds

The current version contains no in-app purchases or subscriptions. Any download charge is displayed and processed by Apple. Refund requests for App Store transactions are handled through Apple, subject to its policies and applicable consumer law. We do not receive your full payment-card details.

6. Ownership

The App's code, artwork and branding remain the property of their respective rights holders. These Terms do not transfer ownership to you.

7. Third-party services

Downloading and updating the App uses Apple services and is subject to Apple's terms. This support site is hosted on GitHub Pages. Duo Fight does not integrate advertising, analytics or purchase-verification SDKs in the current version.

8. Availability and disclaimer

The App is provided “as is” and “as available” to the extent permitted by law. We do not promise uninterrupted or error-free operation or compatibility with every device. Updates may change features. Nothing in these Terms excludes guarantees or remedies that cannot legally be excluded.

9. Liability

To the extent permitted by applicable law, we are not liable for indirect or consequential losses arising from use of the App, including loss of locally stored progress. This does not exclude liability for fraud, intentional misconduct or any liability that cannot legally be limited.

10. Changes

We may update these Terms and will identify the current version using the date above. Where required by applicable law, material changes will require appropriate notice or consent.

11. Governing law

These Terms are governed by the laws of the Republic of Korea, except where mandatory local consumer law provides otherwise.
