DropVolley Terms of Service

Last updated: June 2026

AGREEMENT TO OUR LEGAL TERMS

We are Can Ayan ("Company," "we," "us," "our"), a sole operator established in the Republic of Ireland (Dublin).

We operate the mobile application DropVolley (the "App"), as well as any other related products and services that refer or link to these legal terms (the "Legal Terms") (collectively, the "Services"). DropVolley is a tennis-IQ coaching and training application offering daily court-sense drills, scenario-based quizzes with explanations, a personal Tennis Profile self-assessment with development goals, a match journal with progress analytics, training programs, a mobility library, and an optional AI tennis coach.

You can contact us by email at info@kalibrefin.com or by mail to Dublin, Republic of Ireland.

These Legal Terms constitute a legally binding agreement made between you, whether personally or on behalf of an entity ("you"), and Can Ayan, concerning your access to and use of the Services. You agree that by accessing the Services, you have read, understood, and agreed to be bound by all of these Legal Terms. IF YOU DO NOT AGREE WITH ALL OF THESE LEGAL TERMS, THEN YOU ARE EXPRESSLY PROHIBITED FROM USING THE SERVICES AND YOU MUST DISCONTINUE USE IMMEDIATELY.

Supplemental terms and conditions or documents that may be posted on the Services from time to time are hereby expressly incorporated herein by reference. We reserve the right, in our sole discretion, to make changes or modifications to these Legal Terms from time to time. We will alert you about any changes by updating the "Last updated" date of these Legal Terms, and you waive any right to receive specific notice of each such change. It is your responsibility to periodically review these Legal Terms to stay informed of updates. You will be subject to, and will be deemed to have been made aware of and to have accepted, the changes in any revised Legal Terms by your continued use of the Services after the date such revised Legal Terms are posted.

The Services are intended for users who are at least 16 years old. Persons under the age of 16 are not permitted to use or register for the Services.

PLEASE READ SECTIONS 8 (HEALTH, FITNESS, AND SAFETY), 9 (AI COACH), 14 (DISCLAIMER), 15 (LIMITATION OF LIABILITY), 16 (INDEMNIFICATION), AND 17 (DISPUTE RESOLUTION) CAREFULLY. They contain important health and safety acknowledgments, an assumption-of-risk clause, disclaimers, a limitation of our liability, an indemnification by you, and our approach to dispute resolution. These affect your legal rights. If you are a consumer resident in the European Union, the European Economic Area, or the United Kingdom, your mandatory statutory consumer rights under the law of your country of residence apply on top of these Legal Terms and cannot be waived. Nothing in these Legal Terms limits those rights.

We recommend that you print a copy of these Legal Terms for your records.

1. OUR SERVICES

The information provided when using the Services is not intended for distribution to or use by any person or entity in any jurisdiction or country where such distribution or use would be contrary to law or regulation or which would subject us to any registration requirement within such jurisdiction or country. Accordingly, those persons who choose to access the Services from other locations do so on their own initiative and are solely responsible for compliance with local laws, if and to the extent local laws are applicable.

DropVolley is an informational and educational tennis-training product. It is not a medical device, and it is not a substitute for professional medical, fitness, physiotherapy, or in-person coaching advice. Your use of the training, mobility, and AI Coach features is subject to the health and safety acknowledgments in Section 8 and the AI disclosures in Section 9.

2. INTELLECTUAL PROPERTY RIGHTS

Our intellectual property

We are the owner or the licensee of all intellectual property rights in our Services, including all source code, databases, functionality, software, application designs, audio, video, text, photographs, court diagrams, drills, quizzes, training programs, mobility flows, and graphics in the Services (collectively, the "Content"), as well as the trademarks, service marks, and logos contained therein (the "Marks").

Our Content and Marks are protected by copyright and trademark laws (and various other intellectual property rights and unfair competition laws) and treaties around the world. The Content and Marks are provided in or through the Services "AS IS" for your personal, non-commercial use only.

Your use of our Services

Subject to your compliance with these Legal Terms, including the "PROHIBITED ACTIVITIES" section below, we grant you a non-exclusive, non-transferable, revocable license to access the Services and to use the Content to which you have properly gained access, solely for your personal, non-commercial use on devices you own or control.

Except as set out in this section or elsewhere in our Legal Terms, no part of the Services and no Content or Marks may be copied, reproduced, aggregated, republished, uploaded, posted, publicly displayed, encoded, translated, transmitted, distributed, sold, licensed, or otherwise exploited for any commercial purpose whatsoever, without our express prior written permission. If you wish to make any use of the Services, Content, or Marks other than as set out in this section, please address your request to info@kalibrefin.com.

We reserve all rights not expressly granted to you in and to the Services, Content, and Marks. Any breach of these Intellectual Property Rights will constitute a material breach of our Legal Terms and your right to use our Services will terminate immediately.

Your feedback

By directly sending us any question, comment, suggestion, idea, feedback, or other information about the Services ("Submissions"), you agree that we can use and share such Submissions for any lawful purpose, commercial or otherwise, without acknowledgment or compensation to you. You warrant that your Submissions are original to you and do not constitute confidential information.

3. USER REPRESENTATIONS

By using the Services, you represent and warrant that: (1) all registration information you submit will be true, accurate, current, and complete; (2) you will maintain the accuracy of such information and promptly update it as necessary; (3) you have the legal capacity and you agree to comply with these Legal Terms; (4) you are at least 16 years of age; (5) you will not access the Services through automated or non-human means, whether through a bot, script, or otherwise; (6) you will not use the Services for any illegal or unauthorized purpose; and (7) your use of the Services will not violate any applicable law or regulation.

If you provide any information that is untrue, inaccurate, not current, or incomplete, we have the right to suspend or terminate your account and refuse any and all current or future use of the Services (or any portion thereof).

4. USER REGISTRATION

You may register for the Services using Sign in with Apple. You are responsible for keeping your account credentials and device secure, and you are responsible for all activity that occurs through your account. We reserve the right to remove, reclaim, or change any display name you select if we determine, in our sole discretion, that it is inappropriate, obscene, or otherwise objectionable.

5. PURCHASES AND PAYMENT

DropVolley is offered exclusively as a paid auto-renewing subscription. All purchases are processed by Apple through your App Store account under Apple's billing terms; we do not collect or store your payment card or payment instrument details.

You agree to provide current, complete, and accurate account information and to keep your Apple ID payment information up to date so that your transactions can be completed. Prices are displayed in the App at the moment of purchase and may vary by region. We may change prices at any time; existing subscribers continue to be billed at the price they signed up for until their next renewal, and any price change will be communicated to you in accordance with applicable law.

Refunds are handled by Apple at its sole discretion. We cannot issue refunds directly. Refund requests must be submitted to Apple at https://reportaproblem.apple.com.

6. SUBSCRIPTIONS

Hard paywall — no free tier

DropVolley requires a paid auto-renewing subscription to use. There is no free tier and no free content. A subscription unlocks the whole App — daily court-sense drills, scenario quizzes and explanations, the Tennis Profile and development goals, the match journal and progress analytics, training programs, the full mobility library, and the AI Coach (an optional in-subscription feature; see Section 9).

Plans

DropVolley offers two auto-renewing subscription plans:

Weekly — $9.99 per week. No free trial.
Annual — $59.99 per year. Includes a 3-day free trial for eligible new subscribers.

Billing and renewal

Your subscription will continue and automatically renew at the end of each billing period unless it is canceled at least 24 hours before the current period ends. Your Apple ID account is charged for renewal within 24 hours prior to the end of the current period. You consent to Apple charging your payment method on a recurring basis until you cancel.

Free trial (Annual plan only)

The Annual plan's 3-day free trial automatically converts to a paid annual subscription at the end of the trial unless canceled at least 24 hours before the trial ends. The Weekly plan has no trial. Any unused portion of a free trial is forfeited when you purchase a subscription.

Manage and cancel

You can manage or cancel your subscription at any time in iOS Settings → Apple ID → Subscriptions, or via Profile → Manage subscription in DropVolley. Cancellation takes effect at the end of the current paid period. Restore Purchases is supported for re-establishing an active subscription on a new or reinstalled device.

7. PROHIBITED ACTIVITIES

You may not access or use the Services for any purpose other than that for which we make the Services available. As a user of the Services, you agree not to:

Systematically retrieve data or other Content from the Services to create or compile, directly or indirectly, a collection, compilation, database, or directory without written permission from us.
Circumvent, disable, or otherwise interfere with security-related features of the Services, including features that prevent or restrict the use or copying of any Content, or that enforce paywalls, rate limits, or usage limitations.
Trick, defraud, or mislead us or other users, or attempt to learn sensitive account information.
Use the Services in a manner inconsistent with any applicable laws or regulations, or for any illegal or unauthorized purpose.
Use the Services to harass, abuse, defame, threaten, harm, or impersonate any person.
Engage in any automated use of the system, such as using scripts, data mining, robots, scrapers, or similar data gathering and extraction tools.
Except as permitted by applicable law, decipher, decompile, disassemble, or reverse engineer any of the software comprising or making up a part of the Services.
Copy, adapt, scrape, or republish the Services' Content (including quizzes, training programs, mobility flows, drills, tips, or court diagrams) outside the App.
Use the Services as part of any effort to compete with us or to develop a competing product or service.
Interfere with, disrupt, or create an undue burden on the Services or the networks or services connected to the Services.
Sell or otherwise transfer your profile or account.
Misuse, abuse, or attempt to overload the AI Coach feature, or use it to generate unlawful, harmful, or abusive content.

8. HEALTH, FITNESS, AND SAFETY

DropVolley provides educational content about tennis decision-making, training, and mobility. DropVolley is not a medical device and is not a substitute for professional medical, fitness, physiotherapy, or coaching advice.

8.1 Consult a professional first

Before starting any training program, mobility flow, or tennis-related physical activity in DropVolley, you should consult a qualified physician, physiotherapist, or certified strength-and-conditioning specialist — especially if you have any heart condition, high blood pressure, joint condition, musculoskeletal injury, dizziness, chronic pain, or other medical condition; are recovering from surgery or injury; are pregnant or recently gave birth; take medication that could be affected by physical exertion; are over 65 or have not exercised regularly in the past 6 months; or have any other condition that could be aggravated by exercise.

If you experience pain, dizziness, shortness of breath, nausea, or any unusual symptoms during or after using DropVolley, stop immediately and seek medical attention.

8.2 Assumption of risk

You acknowledge that physical activity — including tennis, strength training, plyometrics, mobility work, conditioning, and any movement performed in connection with DropVolley — carries an inherent risk of personal injury (including serious injury, permanent disability, or death) and property damage. By using DropVolley, you knowingly, voluntarily, and expressly assume all such risks. You agree that you are physically capable of performing the activities you choose to attempt, and that you are solely responsible for evaluating your own fitness level, technique, equipment, and environment.

8.3 No supervision; informational use only

DropVolley delivers self-directed training content. You are not supervised by a coach or trainer through the App. Form cues, prescriptions, and rep counts are general guidance, not personalized instruction. The tips, scenarios, training programs, mobility flows, and coaching notes reflect general coaching opinions and tennis conventions — not absolute truths and not advice tailored to you. Nothing in DropVolley constitutes medical, diagnostic, therapeutic, or treatment advice. You are responsible for the safety and condition of any equipment, court, gym, or location you use, and for adequate warm-up, hydration, nutrition, recovery, and recognizing your own limits.

9. AI COACH AND AI-GENERATED CONTENT

DropVolley includes optional AI features powered by two third-party AI providers — Google LLC (via the Gemini API, United States) and Anthropic, PBC (via Claude, United States). Each AI feature is off until you explicitly consent to it in the App, and no data is sent to the relevant provider until you agree. AI-generated responses are produced by software, not by a human coach.

The optional AI Coach chat is powered by Anthropic's Claude. When you use the AI Coach, DropVolley shares with Anthropic your typed messages, your profile (level and focus), your Tennis Profile (level, style, and goals), your recent matches, scores, and self-ratings, and your quiz mistake patterns — solely to generate the Coach's replies.

DropVolley also offers optional AI features powered by Google's Gemini API: AI Swing Analysis, AI Match coaching (pre-match plan feedback, post-match analysis, and a pre-match mental check), and Doubles compatibility analysis. For AI Swing Analysis, the App compresses a short swing video and sends the video itself to Google to generate a score and technique coaching; the video is also saved on your device for your history and is not stored on our servers. For Match coaching, the mental check, and Doubles compatibility, the App sends text summaries to Google. These AI outputs are informational only, are not medical, physiotherapy, diagnostic, or professional coaching advice, and are subject to all of the same disclaimers, hallucination and accuracy warnings, and your sole-responsibility obligations described in this Section 9 and in Sections 8, 14, 15, and 16.

Under the providers' paid/commercial API terms, your inputs and outputs are not used to train their models. Further detail is provided in our Privacy Policy.

You acknowledge and accept that the output of any AI feature (the AI Coach, AI Swing Analysis, AI Match coaching, the pre-match mental check, and Doubles compatibility analysis) may hallucinate (invent drills, tactics, programs, statistics, or features that do not exist), misread your data, contradict reality or established tennis principles, get tactics wrong for your level, opponent, or surface, reflect biases or omissions in its training data, and be unavailable, slow, or incorrect at any time without notice.

You are solely responsible for evaluating every AI suggestion against your own judgment, your coach's input, and your real-world context before acting on it. The AI features are reflection tools, not a substitute for a qualified human coach, physiotherapist, physician, or trainer. We do not warrant, guarantee, or accept liability for the accuracy, completeness, reliability, or usefulness of any AI response, for any decision you make on its basis, or for the availability or performance of the third-party AI providers' systems. The disclaimers, releases, and indemnifications in Sections 8, 14, 15, and 16 apply in full to all AI features.

10. MOBILE APPLICATION LICENSE

Use license

If you access the Services via the App, we grant you a revocable, non-exclusive, non-transferable, limited right to install and use the App on wireless electronic devices owned or controlled by you, strictly in accordance with these Legal Terms. You shall not, except as permitted by applicable law: (1) decompile, reverse engineer, disassemble, attempt to derive the source code of, or decrypt the App; (2) make any modification, adaptation, improvement, or derivative work from the App; (3) violate any applicable laws in connection with your use of the App; (4) remove, alter, or obscure any proprietary notice posted by us; (5) use the App for any revenue-generating endeavor or commercial enterprise for which it is not intended; (6) make the App available over a network permitting access by multiple devices or users at the same time; or (7) use the App to create a product or service that is competitive with or a substitute for the App.

Apple-specific terms

These Legal Terms are between you and us, not Apple, and Apple is not responsible for the App or its content. The license granted to you is limited to a non-transferable license to use the App on an Apple-branded device that you own or control, as permitted by the App Store's Usage Rules. We, not Apple, are solely responsible for providing any maintenance and support for the App. 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 (if any); to the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the App. Apple is not responsible for addressing any claims by you or any third party relating to the App, including product-liability claims, claims that the App fails to conform to any legal or regulatory requirement, and claims arising under consumer-protection law. In the event of any third-party claim that the App infringes intellectual property rights, we (not Apple) will be solely responsible for the investigation, defense, settlement, and discharge of that claim. You represent that you are not located in a country subject to a U.S. Government embargo and are not on any U.S. Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Legal Terms and may enforce them against you as a third-party beneficiary.

11. PRIVACY POLICY

We care about data privacy and security. Please review our Privacy Policy, which is incorporated into these Legal Terms by reference. By using the Services, you agree to be bound by our Privacy Policy. As the data controller, we process your personal data in accordance with the EU General Data Protection Regulation (GDPR), the Irish Data Protection Act 2018, and, where applicable, the UK GDPR and the California Consumer Privacy Act (CCPA).

12. TERM AND TERMINATION

These Legal Terms shall remain in full force and effect while you use the Services. You may delete your account at any time via Profile → Delete account.

WE RESERVE THE RIGHT, IN OUR SOLE DISCRETION AND WITHOUT NOTICE OR LIABILITY, TO DENY ACCESS TO AND USE OF THE SERVICES TO ANY PERSON FOR BREACH OF ANY REPRESENTATION, WARRANTY, OR COVENANT CONTAINED IN THESE LEGAL TERMS OR OF ANY APPLICABLE LAW OR REGULATION, including where a user abuses the App or the AI Coach, attempts fraud, poses a safety risk, or generates chargebacks. Where reasonable, we will notify you and give you a chance to respond, but we are not obligated to do so where immediate action is needed to protect users or our Services.

Sections 8 (health and safety), 9 (AI Coach), 14 (disclaimer), 15 (limitation of liability), 16 (indemnification), 17 (governing law and dispute resolution), and 18 (miscellaneous) survive termination.

13. MODIFICATIONS AND INTERRUPTIONS

We reserve the right to add, change, or remove the contents or features of the Services at any time or for any reason at our sole discretion. We cannot guarantee the Services will be available at all times. We may experience hardware, software, or other problems, or need to perform maintenance, resulting in interruptions, delays, or errors. You agree that we have no liability for any loss, damage, or inconvenience caused by your inability to access or use the Services during any downtime or discontinuance. Nothing in these Legal Terms obligates us to maintain and support the Services or to supply any corrections, updates, or releases.

14. DISCLAIMER

THE SERVICES ARE PROVIDED ON AN "AS-IS" AND "AS-AVAILABLE" BASIS. YOU AGREE THAT YOUR USE OF THE SERVICES WILL BE AT YOUR SOLE RISK. TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, IN CONNECTION WITH THE SERVICES AND YOUR USE THEREOF, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We make no warranties or representations about the accuracy or completeness of the Services' Content, and we assume no liability for any (1) errors, mistakes, or inaccuracies of Content; (2) personal injury or property damage of any nature resulting from your access to and use of the Services; (3) any interruption or cessation of transmission to or from the Services; or (4) any bugs, viruses, or the like which may be transmitted to or through the Services by any third party. We do not warrant that the Services will meet your requirements, be uninterrupted, timely, secure, or error-free, or result in any particular fitness, performance, or skill outcome. Some jurisdictions do not allow the exclusion of certain warranties; in those jurisdictions, only the exclusions permitted by your local law apply.

15. LIMITATION OF LIABILITY

IN NO EVENT WILL WE OR OUR CONTRACTORS, AGENTS, PARTNERS, AFFILIATES, OR LICENSORS BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY DIRECT, INDIRECT, CONSEQUENTIAL, EXEMPLARY, INCIDENTAL, SPECIAL, OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, LOST DATA, LOSS OF GOODWILL, PERSONAL INJURY, OR PROPERTY DAMAGE ARISING FROM YOUR USE OF THE SERVICES, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. Notwithstanding anything to the contrary contained herein, our total cumulative liability to you for all claims arising out of or related to the Services — regardless of the form of action or legal theory — will not exceed the greater of (a) the total amount you paid us in the twelve (12) months preceding the event giving rise to the claim, or (b) fifty US dollars ($50).

Certain laws do not allow limitations on implied warranties or the exclusion or limitation of certain damages. If these laws apply to you, some or all of the above disclaimers or limitations may not apply, and you may have additional rights. Nothing in these Legal Terms limits any liability that cannot be limited under applicable law, including liability for death or personal injury caused by our negligence, for fraud, or under mandatory EU/UK consumer law.

16. INDEMNIFICATION

You agree to defend, indemnify, and hold us harmless, including our contractors, agents, partners, affiliates, and licensors, from and against any loss, damage, liability, claim, or demand, including reasonable attorneys' fees and expenses, made by any third party due to or arising out of: (1) your use or misuse of the Services; (2) your breach of these Legal Terms; (3) any breach of your representations and warranties set forth in these Legal Terms; (4) your violation of the rights of a third party, including intellectual property rights; or (5) any injury, loss, or harm resulting from any activity you undertake on the basis of DropVolley content, including quiz answers, training prescriptions, mobility instructions, tips, and AI Coach output. We reserve the right, at your expense, to assume the exclusive defense and control of any matter for which you are required to indemnify us, and you agree to cooperate with our defense of such claims.

17. GOVERNING LAW AND DISPUTE RESOLUTION

17.1 Governing law

These Legal Terms and your use of the Services are governed by and construed in accordance with the laws of Ireland, without regard to its conflict-of-laws principles. If you are a consumer, the mandatory consumer-protection laws of your country of residence continue to apply where they provide stronger protection; these Legal Terms do not override those rights.

17.2 Informal resolution first

Before filing any claim, you agree to try to resolve it informally by emailing info@kalibrefin.com with a clear description of the dispute. We will try to respond within 30 days. Many disputes are resolved this way without escalating.

17.3 Online dispute resolution (EU consumers)

If you are a consumer resident in the European Union, you may submit complaints to the European Commission's Online Dispute Resolution platform at https://ec.europa.eu/consumers/odr. We are not obliged to participate in ODR proceedings and prefer to resolve disputes directly through the email above.

17.4 Courts

If informal resolution fails and you are a consumer, you may bring proceedings in the courts of your country of residence and you have the benefit of mandatory consumer-protection rules under the law of that country. If you are not acting as a consumer (for example, you are a business, sole trader, or otherwise acting in a professional capacity), any dispute arising out of or in connection with these Legal Terms or the Services will be subject to the exclusive jurisdiction of the courts of Ireland.

17.5 Optional arbitration

The parties may, by mutual written agreement after a dispute arises, refer the dispute to confidential arbitration in Ireland under the Arbitration Act 2010. This section does not require you to arbitrate, and nothing in these Legal Terms forces a consumer to waive their right to bring a claim in court.

17.6 No class actions outside permitted regimes

Except where prohibited by law (including under EU consumer-protection law), claims will be brought on an individual basis. This clause does not affect any right to participate in a collective-redress mechanism established by, or available under, mandatory law in your country of residence.

18. MISCELLANEOUS

These Legal Terms and any policies or operating rules posted by us in respect to the Services constitute the entire agreement and understanding between you and us, and supersede any prior agreements. Our failure to exercise or enforce any right or provision of these Legal Terms shall not operate as a waiver of such right or provision. We may assign any or all of our rights and obligations to others at any time; you may not assign or transfer these Legal Terms or your account without our written consent. We shall not be responsible or liable for any loss, damage, delay, or failure to act caused by any cause beyond our reasonable control, including natural disasters, war, terrorism, pandemic, labor disputes, or internet, power, or governmental disruptions. If any provision or part of a provision of these Legal Terms is determined to be unlawful, void, or unenforceable, that provision is deemed severable and does not affect the validity and enforceability of any remaining provisions, and will be modified to the minimum extent necessary to make it enforceable. There is no joint venture, partnership, employment, or agency relationship created between you and us as a result of these Legal Terms. You agree that these Legal Terms will not be construed against us by virtue of having drafted them.
