Terms of Use

Last updated: 28 September 2026

These Terms of Use (the “Terms”) form a binding agreement between you and OZLab (“OZLab”, “we”, “us” or “our”) and govern your access to and use of the Smashphone application for iPhone and Apple Watch (the “App”), the website at smashphone.app and its pages (the “Website”), and the online features we operate for them, including the court code service, the online match relay and the leaderboard (together with the App and the Website, the “Services”).

By downloading, installing, accessing or using any of the Services, you confirm that you have read, understood and agree to be bound by these Terms and by our Privacy Policy, which explains how we handle personal data. If you do not agree, do not use the Services.

Smashphone is a physically active game in which you swing your phone or watch. Please read Section 4 (Safety and Physical Activity) before you play. Sections 12 and 13 disclaim warranties and limit our liability to the extent permitted by law.

1. Relationship to the Apple Licensed Application EULA

The App is distributed through Apple’s App Store. Your licence to use the App is granted under Apple’s Licensed Application End User License Agreement (the “Standard EULA”). These Terms supplement the Standard EULA and set out additional terms that apply to the App and to the other Services. If these Terms and the Standard EULA conflict with respect to the App, the Standard EULA prevails to the extent of the conflict.

Your use of the App Store, your Apple Account and payments made through Apple is also subject to Apple’s own terms, including the Apple Media Services Terms and Conditions.

2. Eligibility

You may use the Services only if you are able to form a binding contract with us, or, if you are a minor under the laws of your place of residence, with the involvement and consent of a parent or legal guardian, who agrees to these Terms on your behalf and is responsible for your use of the Services, including any purchases.

You must not use the Services if you are barred from doing so under the laws of any applicable jurisdiction.

3. Licence and Restrictions

Subject to your compliance with these Terms and the Standard EULA, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable and revocable licence to install and use the App on Apple-branded devices that you own or control, as permitted by the App Store’s Usage Rules, and to access the Website and the online features of the Services, in each case solely for your personal, non-commercial entertainment.

Except to the extent that applicable law expressly permits it notwithstanding this restriction, you must not:

• copy, modify, adapt, translate or create derivative works of the Services or any part of them;
• decompile, disassemble, reverse engineer or otherwise attempt to derive the source code of the App or of any server, relay or other component of the Services;
• rent, lease, lend, sell, sublicense, redistribute or otherwise make the Services available to any third party, or use them for any commercial purpose, including public or paid events, without our prior written consent;
• circumvent, disable or interfere with any feature that restricts access to paid content, enforces usage limits (such as trial matches) or protects the security of the Services;
• use cheats, bots, scripts, modified clients or any other means to submit scores, points or match results that were not produced by genuine play;
• access the Services by automated means, overload or disrupt our servers or relay, or attempt to gain unauthorised access to any system or data; or
• use the Services in any way that violates applicable law or the rights of any other person.

All rights not expressly granted to you are reserved by OZLab and its licensors.

4. Safety and Physical Activity

The Services are designed to be played by physically swinging an iPhone or an Apple Watch. Physical activity involves an inherent risk of injury and of damage to property. You play at your own risk and are solely responsible for your own safety, for the safety of other people and animals around you, and for your devices and other property. In particular, you should:

• hold your iPhone firmly at all times and use a wrist strap or secure grip where one is available, and fasten your Apple Watch securely;
• make sure there is enough clear space around you, free of people, pets, furniture, screens, windows, light fittings and other obstacles, before and while you play;
• not play in any place or situation where a loss of attention could be dangerous, such as near stairs, roads or water;
• stop playing immediately if you feel pain, dizziness, shortness of breath, fatigue or any discomfort, and take regular breaks; and
• consult a physician before playing if you are pregnant or have any heart, respiratory, musculoskeletal, neurological or other medical condition, or if you are unsure whether vigorous activity is suitable for you.

Minors should play only under the supervision of a responsible adult.

The App is an entertainment product. It is not a medical device, and any activity, energy, heart-rate or workout figures it shows or saves to Apple Health are estimates for general information only and must not be relied on for medical, health or fitness decisions.

Damage to your devices caused by dropping, throwing, striking or otherwise mishandling them while playing is not covered by us. To the maximum extent permitted by applicable law, and subject to Section 14, we are not responsible for any injury, loss or damage resulting from the manner in which you use the Services.

5. In-App Purchases and Subscriptions

The App can be downloaded free of charge, and some content, such as badminton against the computer, is free to play. Other content and features are available only through optional in-app purchases. The following plans are currently offered:

• All Sports Pass — a one-time, non-consumable purchase that unlocks every sport available in the App for as long as the App remains available to you. It does not include two-player play.
• Online — a monthly auto-renewable subscription that, while active, unlocks every sport and all two-player play: Versus with a friend on the same local network, a friend joining from another network through our relay, and quick match.
• Online Forever — a one-time, non-consumable purchase that provides everything included in Online, with no renewal.

Owners of the All Sports Pass may be offered Online and Online Forever at a reduced price. Certain sports may be offered with a limited number of free trial matches per device; trial allowances are at our discretion and may be changed or withdrawn. The content and features included in each plan are described on the purchase screen in the App at the time of purchase.

Payment. All purchases are made through Apple and are charged to the payment method associated with your Apple Account. Prices are shown in the App before you confirm a purchase, may vary by country or region, and may include applicable taxes. We do not receive or store your payment card details.

Auto-renewal. Online is billed monthly in advance. Your subscription renews automatically at the end of each billing period at the then-current price unless you cancel it at least 24 hours before the end of the current period. Your Apple Account will be charged for renewal within 24 hours before the end of the current period. You can manage or cancel your subscription at any time in your device’s Settings under your Apple Account’s Subscriptions. Cancellation takes effect at the end of the current billing period; you retain access until then. When a subscription ends, content and features that depend on it will no longer be available unless you hold another plan that includes them. Purchasing Online Forever does not cancel an existing Online subscription; you must cancel it yourself.

Price changes. We may change prices from time to time. Price changes to an auto-renewable subscription are notified and, where required, consented to through Apple in accordance with Apple’s policies, and take effect from the next renewal period.

Refunds. Refunds are handled by Apple in accordance with Apple’s policies and applicable law; we are unable to issue refunds ourselves. You can request a refund at reportaproblem.apple.com. Nothing in these Terms affects any statutory right you may have to withdraw from or cancel a purchase.

Restoring purchases. Non-consumable purchases and subscriptions are tied to your Apple Account and can be restored on your other devices signed in to the same Apple Account using “Restore Purchases” in the App.

Online matches. In an online or two-player match, the plan held by the player who hosts the session covers the other player for that match. Quick match pairs you with another player who is searching at the same time; when no other player is available, the App may seat its own computer-controlled opponent, which is identified as such in the App.

Changes to content. We may add, change or retire sports, modes and features over time. We will not remove the core benefit of a plan you have purchased while we continue to make the App available, except where required by law, by Apple, or for reasons of security or technical necessity.

6. Leaderboard, Player Names and Medals

The App includes a global leaderboard operated by us. Points are calculated by our servers from the results of finished matches submitted by the App. Taking part is optional and can be switched off in the App’s account settings.

If you choose a player name, it is displayed publicly to all users of the leaderboard worldwide. Your name must not be offensive, obscene, hateful, discriminatory or misleading, must not infringe anyone’s rights, and must not impersonate any person or organisation. We may reject, reset or remove any name, entry, score or medal, and may exclude any player from the leaderboard, if we reasonably believe it breaches these Terms or was obtained by cheating, tampering or exploiting a defect.

Points, rankings and medals, including monthly medals awarded to top-ranked players and medals associated with purchased plans, are provided for entertainment only. They have no monetary value, cannot be purchased, sold, transferred or exchanged for money or anything of value, and may be recalculated, reset or discontinued.

Sign in with Apple is optional and is used only to keep your leaderboard identity across devices. Once signed in, you can delete your leaderboard account at any time from the App’s account settings, which permanently deletes your name, points, match records and medals from our servers. You may also ask us to delete your leaderboard data by contacting us as described in Section 17.

7. Online Play and Conduct

When you play with other people, you agree to behave fairly and respectfully. You must not harass, threaten or abuse other players, share room codes to disrupt other people’s sessions, or attempt to manipulate matchmaking, match results or rankings.

Online features depend on the internet, on your local network and on third-party infrastructure, and may be affected by latency, interruption or unavailability. We do not guarantee that any match can be started, completed or recorded.

8. Intellectual Property

The Services and all content and materials in them, including software, game designs, graphics, sounds, music, text, and the Smashphone name and logos, are owned by or licensed to OZLab and are protected by intellectual property laws. Other than the limited licence in Section 3, nothing in these Terms grants you any right in them. “Apple”, “iPhone”, “Apple Watch”, “App Store” and “Apple Health” are trademarks of Apple Inc.; other trademarks belong to their respective owners.

If you send us ideas, suggestions or other feedback, you grant us a worldwide, royalty-free, perpetual and irrevocable right to use it for any purpose without obligation to you.

9. Third-Party Services and Terms

The Services rely on and may link to products and services provided by third parties, including Apple (the App Store, Sign in with Apple and Apple Health), your web browser and your network providers. Your use of those products and services is governed by the third parties’ own terms and privacy policies, and you must comply with any applicable third-party terms when using the Services. We are not responsible for third-party products or services.

10. Availability, Updates and Changes

We may update the Services from time to time, including to fix defects, improve performance, add or remove features, or comply with law. Some updates may be required to continue using the Services. The Services may not be available in every country or on every device or operating-system version.

We may suspend or discontinue all or part of the Services, temporarily or permanently. Where we discontinue the App entirely, we will give reasonable advance notice where practicable.

11. Suspension and Termination

You may stop using the Services at any time by deleting the App and, if you have one, deleting your leaderboard account in the App.

We may suspend or terminate your access to all or part of the Services, including the leaderboard and online play, if you materially or repeatedly breach these Terms, if required by law, or if necessary to protect other users or the security of the Services. Sections that by their nature should survive termination, including Sections 8 and 12 to 17, survive.

12. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE”, WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. OZLAB DISCLAIMS ALL WARRANTIES AND CONDITIONS, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, SATISFACTORY QUALITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, QUIET ENJOYMENT AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE OR SECURE, OR THAT MOTION DETECTION WILL INTERPRET EVERY MOVEMENT AS YOU INTEND.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you. In that case, such warranties are limited to the minimum extent and duration permitted by law.

13. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL OZLAB BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL OR OPPORTUNITY, ARISING OUT OF OR IN CONNECTION WITH THE SERVICES OR THESE TERMS, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OZLAB’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR IN CONNECTION WITH THE SERVICES OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNT YOU PAID FOR IN-APP PURCHASES IN THE APP DURING THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE LIABILITY, AND (B) FIFTY US DOLLARS (US$50).

14. Your Statutory Rights

Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation, or affects any rights you have as a consumer under the mandatory laws of the country in which you live. Sections 12 and 13 apply only to the extent permitted by those laws.

15. Additional Terms for the App Store

The following terms apply to the App as downloaded from Apple’s App Store:

• Acknowledgement. These Terms are concluded between you and OZLab only, and not with Apple Inc. (“Apple”). OZLab, not Apple, is solely responsible for the App and its content.
• Scope of licence. Your licence to use the App is limited to a non-transferable licence to use the App on any Apple-branded products that you own or control, as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions, except that the App may be accessed and used by other accounts associated with you via Family Sharing or volume purchasing where the App Store permits it.
• Maintenance and support. OZLab is solely responsible for providing any maintenance and support services for the App. Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the App.
• Warranty. OZLab is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App to you; to the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty will be OZLab’s sole responsibility, subject to these Terms.
• Product claims. OZLab, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession and/or use of the App, including (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy or similar legislation, including in connection with the App’s use of the HealthKit framework.
• Intellectual property rights. In the event of any third-party claim that the App or your possession and use of the App infringes that third party’s intellectual property rights, OZLab, not Apple, will be solely responsible for the investigation, defence, settlement and discharge of any such claim.
• Legal compliance. You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
• Developer contact. Questions, complaints or claims with respect to the App should be directed to OZLab at support@ozlab.xyz.
• Third-party terms. You must comply with applicable third-party terms of agreement when using the App, such as your wireless data service agreement.
• Third-party beneficiary. Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

16. General

Changes to these Terms. We may amend these Terms from time to time. We will post the amended Terms on this page with a new “Last updated” date and, where the changes are material, we will provide reasonable notice, for example in the App or on the Website, before they take effect. By continuing to use the Services after the amended Terms take effect, you accept them. If you do not agree to the amended Terms, you must stop using the Services.

Entire agreement. These Terms, together with the Standard EULA and our Privacy Policy, constitute the entire agreement between you and us regarding the Services and supersede any prior agreements on that subject.

Severability. If any provision of these Terms is held invalid or unenforceable, that provision will be enforced to the maximum extent permissible and the remaining provisions will remain in full force and effect.

No waiver. Our failure to enforce any right or provision of these Terms will not be considered a waiver of that right or provision.

Assignment. You may not assign or transfer these Terms or any rights under them without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganisation or sale of assets, or by operation of law, provided that your rights under them are not diminished.

Language. These Terms are drawn up in English, and a Chinese version is provided. If there is any inconsistency between the two versions, the English version prevails, to the extent permitted by applicable law.
