Terms of Service

1. Agreement and acceptance

These Terms of Service ("Terms") govern your access to and use of the TennisLens mobile application and the TennisLens website (together, the "Service"), operated by TennisLens ("TennisLens", "we", "us", or "our"). By downloading, accessing, or using the Service, you confirm that you accept these Terms and agree to comply with them. If you do not agree, you must not use the Service. Our Privacy Policy also applies and is incorporated into these Terms by reference.

2. Eligibility

You must be at least 13 years old to use the Service. If you are under 18, you may use the Service only with the involvement and consent of a parent or guardian, and only they may make any purchase. By using the Service you confirm that you have the legal capacity to enter into these Terms and that the information you provide is accurate.

3. The Service

TennisLens lets you record or upload short video clips of tennis strokes and receive an automated, AI-generated analysis of your technique, including scores, observations, identified errors, and suggested drills. The Service may also include educational content such as curated "Pro Breakdown" videos. The Service is provided for general informational and educational purposes only.

4. Licence to use the app

Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable licence to download and use the app on a device that you own or control, and to use the Service for your own personal, non-commercial use. You may not copy, modify, distribute, sell, lease, reverse engineer, or attempt to extract the source code of the app, except to the extent that such restriction is prohibited by applicable law.

5. App stores and Apple-specific terms

You obtain the app through, and your use is also subject to the rules of, the relevant app store (the Apple App Store or Google Play). The following terms apply where you download the app from the Apple App Store and form part of the end user licence agreement between you and TennisLens (and the standard Apple Licensed Application End User Licence Agreement applies to the extent it is not inconsistent with these Terms):

• These Terms are between you and TennisLens only, and not with Apple. Apple is not responsible for the app or its content.
• Apple has no obligation to provide any maintenance or support for the app.
• To the maximum extent permitted by law, Apple has no warranty obligation with respect to the app. If the app fails to conform to any applicable warranty, you may notify Apple and (where applicable) Apple may refund the purchase price; Apple has no other warranty obligation.
• Apple is not responsible for addressing any claims relating to the app, including product liability, legal or regulatory non-compliance, or consumer protection claims.
• Apple is not responsible for investigating, defending, settling, or discharging any third-party claim that the app infringes intellectual property rights.
• You represent that you are not located in a country subject to a U.S. Government embargo or designated as "terrorist supporting", and that you are not on any U.S. Government restricted-parties list.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

TennisLens, and not Apple or Google, is solely responsible for the app and its content. Any maintenance and support, and any questions, complaints, or claims relating to the app — including claims that the app fails to conform to a legal or regulatory requirement, product liability claims, intellectual property claims, and consumer protection claims — should be directed to TennisLens at tennislens@moonshard.co.

6. Your clips and content

You retain all ownership of the clips, audio, and notes you submit ("Your Content"). You grant TennisLens a limited, worldwide, royalty-free licence to use, process, and transmit Your Content solely for the purpose of operating the Service and generating your analysis — including sending it to our AI provider as described in our Privacy Policy. This licence ends when processing is complete, because we do not retain your clips or notes.

You represent and warrant that:

• You own or have the necessary rights and permissions to submit Your Content for analysis;
• where Your Content shows other identifiable people, you have any consent required to record them and submit the clip; and
• Your Content does not infringe the rights of any third party or break any law.

7. Acceptable use

You agree not to:

• use the Service for any unlawful, harmful, or fraudulent purpose;
• upload content that is illegal, infringing, obscene, abusive, or that you do not have the right to upload;
• attempt to gain unauthorised access to, interfere with, or disrupt the Service or its infrastructure;
• circumvent, disable, or interfere with usage limits, rate limiting, or security features;
• use automated means to access the Service or to submit content at scale; or
• misuse the Service in any way that could damage, disable, or impair it or interfere with anyone else's use.

Fair use and usage limits. To keep TennisLens fast, affordable, and available for everyone, the Service applies reasonable usage limits — including a daily limit on the number of clips you can analyse. These limits are set for ordinary personal use. Using the Service beyond those limits, or attempting to get around them — for example by using automated tools or scripts, or by using multiple devices, accounts, or identifiers to obtain additional analyses — is considered abuse of the Service. We may throttle, rate-limit, queue, downgrade, suspend, or restrict access where usage exceeds these limits or where we reasonably consider it abusive, excessive, or a risk to the Service or its costs.

8. AI feedback — not coaching or medical advice

The analysis is generated automatically by an artificial intelligence model. It may be incomplete, inaccurate, or unsuitable for your particular situation, and it can vary between clips. The Service is not a substitute for a qualified tennis coach, and it is not medical, physiotherapy, fitness, or other professional advice.

Tennis and physical training carry an inherent risk of injury. You are responsible for exercising within your own ability, warming up properly, and using appropriate technique and equipment. Always consult a suitably qualified professional before acting on any feedback or drill, particularly if you have any injury, pain, or medical condition. You use the analysis and any drills at your own risk.

9. Subscriptions, billing, and cancellation

Some features of the Service may require a paid subscription. Subscriptions, including any free trial and auto-renewing terms, are sold and processed through the Apple App Store or Google Play, and are subject to that store's terms in addition to these Terms. Where a subscription is auto-renewing:

• Payment is charged to your app store account at confirmation of purchase.
• The subscription automatically renews for the same period at the then-current price unless you cancel at least 24 hours before the end of the current period.
• Your account is charged for renewal within 24 hours before the end of the current period.
• If a free trial is offered, any unused portion of a free trial is forfeited when you purchase a subscription, where applicable.
• You can manage or cancel your subscription, and turn off auto-renewal, in your app store account settings at any time.

The current price and billing period are shown in the app at the point of purchase. Prices may change; we will give notice of changes as required and any change will not affect the period you have already paid for. Refunds, where available, are handled by the relevant app store under its policies, and not by TennisLens directly. Nothing in this section affects your statutory rights as a consumer.

10. Intellectual property

The Service, including its software, design, text, graphics, the TennisLens name and logo, and all related intellectual property, is owned by TennisLens or its licensors and is protected by law. Except for the limited licence granted to you in these Terms, no rights are granted to you. You may not use our branding without our prior written permission.

11. Third-party content and links

The Service may display or link to content provided by third parties, including the curated "Pro Breakdown" videos shown through TikTok's embedded player. That content is owned by its respective rights holders and is provided through, and subject to the terms of, the relevant third-party platform. We do not control and are not responsible for third-party content, and its availability is not guaranteed — for example, a third-party video may be removed by its platform at any time. Your use of third-party services is subject to their own terms and privacy policies. TennisLens is not affiliated with, endorsed by, or sponsored by any player, tournament, brand, or governing body referenced in educational content.

12. Availability and changes to the Service

We aim to keep the Service available but we do not guarantee it will be uninterrupted, timely, secure, or error-free. We may add, change, suspend, or remove features, or impose or change usage limits, at any time. The Service may depend on third-party providers (including our AI provider and infrastructure providers) whose availability we do not control.

13. Disclaimers

To the fullest extent permitted by law, the Service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including any implied warranties of satisfactory quality, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the analysis will be accurate, reliable, or suitable for your needs. This section does not exclude or limit any warranty or right that cannot be excluded or limited under applicable law, including the Consumer Rights Act 2015.

14. Limitation of liability

Nothing in these Terms excludes or limits our liability where it would be unlawful to do so. In particular, we do not exclude or limit liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited under the laws of England and Wales, including your statutory rights as a consumer.

Subject to the paragraph above, and to the fullest extent permitted by law:

• We are not liable for any loss or damage that is not reasonably foreseeable, or for any indirect or consequential loss.
• We are not liable for any loss or damage arising from your reliance on the analysis or any drill, from any injury sustained during physical activity, from loss of data stored only on your device, or from the unavailability of, or changes to, third-party content or services.
• Our total liability to you for all claims arising out of or relating to the Service in any 12-month period is limited to the greater of (a) the amount you paid us for the Service in that period, or (b) ten pounds sterling (£10).

If you are a consumer, you have legal rights that these Terms do not affect, and we are responsible to you for foreseeable loss and damage caused by us where the law requires.

15. Indemnity

To the extent permitted by law, you agree to indemnify and hold TennisLens harmless from any claims, losses, and reasonable costs arising out of your breach of these Terms, your misuse of the Service, or Your Content infringing the rights of a third party.

16. Suspension and termination

You may stop using the Service at any time and uninstall the app. We may suspend or end your access to the Service, in whole or in part, if you breach these Terms, misuse the Service, or where we are required to do so by law, or if we discontinue the Service. Sections that by their nature should survive termination (including content licences you have granted, intellectual property, disclaimers, limitation of liability, indemnity, and governing law) will survive.

17. Changes to these terms

We may update these Terms from time to time. When we do, we will update the "Last updated" date above and, for significant changes, provide a more prominent notice where appropriate. Your continued use of the Service after changes take effect means you accept the updated Terms. If you do not agree to the changes, you must stop using the Service.

18. Governing law and your consumer rights

These Terms and any dispute or claim arising out of or in connection with them or the Service are governed by the laws of England and Wales. The courts of England and Wales will have jurisdiction, except that if you are a consumer resident elsewhere in the UK you may bring proceedings in your home courts, and nothing here removes the mandatory consumer protections of your place of residence. If you are a consumer in the EU or elsewhere, you continue to benefit from any mandatory protections of the law of the country where you live.
