Terms of Use

Last updated: April 24, 2026

PLEASE READ THESE TERMS CAREFULLY BEFORE USING THE SERVICE. BY ACCESSING OR USING CUEBALL YOU AGREE TO BE LEGALLY BOUND BY THESE TERMS. IF YOU DO NOT AGREE, DO NOT USE THE SERVICE.

These Terms of Use (“Terms”) govern your access to and use of the cueball platform at cueball.ai and any associated applications or services (collectively, the “Service”), operated by cueball Ltd (“cueball”, “we”, “us”, or “our”), a company registered in England and Wales.

1. Acceptance of terms

By creating an account, clicking “I agree”, accessing, or using any part of the Service, you confirm that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated into these Terms by reference.

If you are accepting on behalf of an organisation, you represent and warrant that you have the authority to bind that organisation to these Terms, and references to “you” include that organisation.

2. Eligibility

You must be at least 16 years of age to use the Service. By using the Service you represent and warrant that you meet this age requirement. If you are under 18, you represent that your parent or legal guardian has reviewed and agrees to these Terms on your behalf.

The Service is not available to any person who has been previously banned from the Service by cueball or to any person located in a country subject to a UK or US government embargo where use of the Service is prohibited.

3. Accounts

To access most features of the Service, you must register for an account. When registering you agree to:

  • Provide accurate, current, and complete information.
  • Maintain and promptly update your information to keep it accurate.
  • Keep your password secure and confidential.
  • Not share your account credentials with any third party.
  • Notify us immediately at support@cueball.ai if you suspect any unauthorised access to or use of your account.

You are solely responsible for all activity that occurs under your account, whether or not you authorised it. cueball is not liable for any loss or damage arising from your failure to comply with this obligation.

We reserve the right to refuse registration or cancel an account at our sole discretion.

4. Subscriptions and billing

The Service is offered on a subscription basis. By selecting a paid plan you authorise us to charge your payment method on a recurring basis in accordance with the selected billing cycle (monthly or annual) until you cancel.

  • Billing cycle: subscriptions begin on the date of purchase and renew automatically at the end of each billing period.
  • Price changes: we reserve the right to change subscription prices. We will give at least 30 days' advance notice to existing subscribers via email before any price increase takes effect. Continued use after the effective date constitutes acceptance of the new price.
  • Taxes: prices shown exclude VAT and any other applicable taxes unless stated otherwise. You are responsible for all applicable taxes in your jurisdiction. We will add VAT where required by law.
  • Failed payments: if your payment method fails, we will retry the charge. If payment cannot be collected within 7 days, your account may be downgraded to the Free tier until payment is updated.
  • Cancellation: you may cancel your subscription at any time from the Billing page. Cancellation takes effect at the end of the current billing period. You retain access to paid features until then.
  • Enterprise: enterprise subscriptions are governed by the order form and these Terms. In the event of a conflict, the order form takes precedence.
  • Free tier: the Free tier may be modified or discontinued at any time with reasonable notice.

All payments are processed by Stripe, Inc. By providing payment information you agree to Stripe's terms of service. cueball does not store your card details.

5. Refund policy

All sales are final. We do not offer refunds for any subscription fees paid, including for unused portions of a billing period, except as required by applicable law.

If you are a consumer based in the United Kingdom or European Economic Area, you have a statutory right to cancel a contract and receive a full refund within 14 days of purchase (the “cooling-off period”), unless you have accessed or used the digital content during that period, in which case the right to cancel may be lost. By accessing any paid content immediately after purchase, you expressly request commencement of the service and acknowledge that the cooling-off right may be forfeited.

Refund requests arising from statutory rights should be sent to support@cueball.ai with your order details.

6. Acceptable use

You agree to use the Service only for lawful purposes and in accordance with these Terms. You agree not to:

  • Share, sell, sublicense, or otherwise transfer your account or access credentials to any third party.
  • Reproduce, distribute, publicly display, publicly perform, create derivative works of, or otherwise exploit any cueball content (including course videos, lessons, labs, quizzes, and written materials) for any commercial or non-personal purpose without our prior written consent.
  • Systematically retrieve, scrape, copy, or index any part of the Service by automated means (bots, crawlers, scrapers) without our express written permission.
  • Attempt to access, probe, or test the security or vulnerability of the Service or any related system or network without authorisation.
  • Circumvent, disable, or otherwise interfere with security-related features, authentication mechanisms, or features that enforce limitations on access or use of content.
  • Upload, post, or transmit any material that is unlawful, harmful, threatening, abusive, harassing, defamatory, vulgar, obscene, hateful, or otherwise objectionable.
  • Impersonate any person or entity, or falsely represent your affiliation with any person or entity.
  • Use the Service to transmit unsolicited commercial communications (spam).
  • Use the Service in any manner that could disable, overburden, damage, or impair the Service or interfere with any other party's use of the Service.
  • Introduce any viruses, trojans, worms, logic bombs, or other material that is malicious or technologically harmful.
  • Use the Service to develop, train, or improve any competing product or service, or to benchmark performance for purposes of competing with cueball.
  • Violate any applicable local, national, or international law or regulation.

Breach of these acceptable use obligations may result in immediate suspension or termination of your account, and we reserve the right to report any violation to law enforcement authorities.

7. Intellectual property

The Service and all content, features, and functionality therein — including but not limited to course videos, lesson text, lab scenarios, quizzes, graphics, software, code, databases, trade marks, logos, and the “cueball” name — are owned by cueball Ltd or its licensors and are protected by copyright, trade mark, patent, and other applicable intellectual property laws in the United Kingdom and internationally.

Subject to your compliance with these Terms and payment of applicable subscription fees, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable licence to access and use the Service and its content solely for your own personal, non-commercial learning purposes. No other licence or right is granted by implication, estoppel, or otherwise.

All rights not expressly granted in these Terms are reserved by cueball Ltd. Any unauthorised use of the Service or content terminates the licence granted in these Terms.

“cueball”, the cueball logo, and any other cueball product or service names are trade marks of cueball Ltd. You may not use these trade marks without our prior written permission.

8. User-generated content

If the Service permits you to submit, post, or otherwise make available any content (including text, images, comments, or forum posts) (“User Content”), you retain all intellectual property rights you hold in that User Content.

By submitting User Content, you grant cueball a worldwide, royalty-free, non-exclusive, sublicensable, perpetual licence to use, reproduce, modify, adapt, publish, translate, distribute, and display that User Content in connection with operating and improving the Service.

You represent and warrant that: (a) you own or have the necessary rights to submit the User Content and to grant the above licence; (b) the User Content does not infringe any third-party intellectual property, privacy, or other rights; and (c) the User Content does not violate any applicable law or these Terms. You are solely responsible for your User Content and the consequences of posting it.

cueball reserves the right (but not the obligation) to monitor, remove, or edit any User Content at our sole discretion, without notice, for any reason including violation of these Terms.

9. AI features

The Service may include features powered by artificial intelligence models, including models provided by Anthropic, PBC. AI-generated content is provided for educational and informational purposes only. It may contain errors, inaccuracies, or outdated information.

cueball expressly disclaims any liability for any loss or damage arising from your reliance on AI-generated content. AI outputs do not constitute professional advice of any kind (including legal, medical, financial, technical, or career advice). Always verify AI-generated information with authoritative sources before acting on it.

You are responsible for any content you submit to AI-powered features. Do not submit any sensitive personal information, confidential business information, classified data, or data whose submission is prohibited by any applicable law or obligation.

10. Third-party services

The Service integrates with third-party services including Stripe (payments), Supabase (infrastructure), and Anthropic (AI). These services are governed by their own terms of service and privacy policies. cueball is not responsible for the practices, availability, or content of any third-party service.

Links to third-party websites on the Service are provided for convenience only and do not constitute an endorsement by cueball of those sites or their content. cueball has no control over and assumes no responsibility for the content, privacy policies, or practices of any third-party sites.

11. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE.

cueball DOES NOT WARRANT THAT: (a) THE SERVICE WILL MEET YOUR REQUIREMENTS; (b) THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE; (c) ANY ERRORS IN THE SERVICE WILL BE CORRECTED; (d) THE SERVICE OR THE SERVERS THAT MAKE THE SERVICE AVAILABLE ARE FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS; OR (e) ANY CONTENT ON THE SERVICE IS ACCURATE, COMPLETE, RELIABLE, CURRENT, OR SUITABLE FOR ANY PURPOSE.

COURSE AND WORKSHOP CONTENT IS PROVIDED FOR EDUCATIONAL PURPOSES ONLY. cueball MAKES NO REPRESENTATION OR WARRANTY THAT COMPLETION OF ANY COURSE, LEARNING PATH, LAB, OR WORKSHOP WILL RESULT IN ANY PARTICULAR EMPLOYMENT OUTCOME, PROFESSIONAL CERTIFICATION, OR SKILL ACQUISITION.

Some jurisdictions do not allow the exclusion of implied warranties, so some of the above exclusions may not apply to you.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL cueball LTD, ITS DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, LICENSORS, OR SERVICE PROVIDERS BE LIABLE FOR ANY:

  • INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES;
  • LOSS OF PROFIT, REVENUE, DATA, BUSINESS, GOODWILL, OR ANTICIPATED SAVINGS;
  • DAMAGE TO REPUTATION OR IMAGE;
  • LOSS OF OR DAMAGE TO DATA OR SYSTEMS;
  • COST OF PROCURING SUBSTITUTE SERVICES;

ARISING OUT OF OR IN CONNECTION WITH THESE TERMS OR THE SERVICE, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT cueball HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, cueball's TOTAL CUMULATIVE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF: (a) THE TOTAL AMOUNT YOU PAID TO cueball IN THE 12-MONTH PERIOD IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM; OR (b) ONE HUNDRED POUNDS STERLING (£100).

The limitations in this section apply regardless of the form of action, the grounds for liability, or whether cueball has been informed of the possibility of such damages. Some jurisdictions do not allow the exclusion or limitation of liability for consequential or incidental damages, so the above limitations may not apply to you.

Nothing in these Terms excludes or limits cueball's liability for: (a) death or personal injury caused by cueball's negligence; (b) fraud or fraudulent misrepresentation; or (c) any liability that cannot be excluded or limited by applicable law.

13. Indemnification

You agree to indemnify, defend, and hold harmless cueball Ltd and its directors, officers, employees, agents, licensors, and service providers from and against any claims, liabilities, damages, judgements, awards, losses, costs, expenses, or fees (including reasonable legal fees) arising out of or relating to:

  • your violation of these Terms;
  • your User Content;
  • your use of the Service in a manner not authorised by these Terms;
  • your violation of any applicable law or the rights of any third party.

cueball reserves the right to assume exclusive control of the defence of any matter for which you are required to indemnify us, and you agree to cooperate with our defence of those claims.

14. DMCA / copyright

We respect intellectual property rights. If you believe that any content on the Service infringes your copyright, please send a written notice to legal@cueball.ai containing:

  • identification of the copyrighted work you claim has been infringed;
  • identification of the material on the Service that is claimed to be infringing, with sufficient detail to locate it;
  • your contact information (name, address, telephone number, email);
  • a statement that you have a good-faith belief that the use is not authorised by the copyright owner, its agent, or the law;
  • a statement, under penalty of perjury, that the information in the notice is accurate and that you are the copyright owner or authorised to act on their behalf;
  • your physical or electronic signature.

We will act expeditiously to investigate and, where appropriate, remove or disable access to allegedly infringing material. Repeat infringers will have their accounts terminated.

15. Suspension and termination

cueball may, in its sole discretion and without prior notice or liability, suspend or terminate your account and access to the Service for any reason, including but not limited to breach of these Terms, suspected fraudulent or abusive activity, extended inactivity, or as required by law.

Upon termination: (a) the licence granted to you in these Terms terminates immediately; (b) you must cease all use of the Service; (c) any subscription fees paid for the current billing period are non-refundable unless otherwise required by law.

You may terminate your account at any time by following the account deletion process described in our documentation. Termination does not relieve you of any obligations accrued prior to termination.

All provisions of these Terms that by their nature should survive termination shall survive, including Sections 7 (Intellectual property), 11 (Disclaimers), 12 (Limitation of liability), 13 (Indemnification), and 17 (Governing law).

16. Force majeure

cueball shall not be liable for any failure or delay in the performance of its obligations under these Terms to the extent that such failure or delay is caused by circumstances beyond cueball's reasonable control, including but not limited to: acts of God, flood, fire, earthquake, pandemic, epidemic, governmental actions, war, terrorism, civil unrest, strikes, labour disputes, power or internet outages, failure of third-party service providers, or cyberattacks. cueball will endeavour to resume performance as soon as reasonably practicable after the event of force majeure.

17. Disputes and governing law

These Terms and any dispute or claim arising out of or in connection with them or their subject matter or formation (including non-contractual disputes or claims) shall be governed by and construed in accordance with the laws of England and Wales.

Before initiating any formal legal proceedings, you agree to first attempt to resolve the dispute informally by contacting us at legal@cueball.ai and giving us 30 days to respond and attempt resolution.

If the dispute cannot be resolved informally, each party irrevocably submits to the exclusive jurisdiction of the courts of England and Wales, except that consumers in the EEA may bring proceedings in their country of residence to the extent required by applicable consumer protection law.

If you are a UK consumer, you may also refer your complaint to the applicable Alternative Dispute Resolution (ADR) body or, for online purchases, to the European Commission's Online Dispute Resolution platform.

18. Class action waiver

TO THE EXTENT PERMITTED BY APPLICABLE LAW, YOU AGREE THAT ANY CLAIM OR DISPUTE ARISING FROM OR RELATING TO THESE TERMS OR THE SERVICE SHALL BE BROUGHT SOLELY IN YOUR INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. YOU WAIVE YOUR RIGHT TO PARTICIPATE IN A CLASS ACTION.

Nothing in this section limits any right you may have to bring an individual action in small claims court.

19. Severability and waiver

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, that provision shall be modified to the minimum extent necessary to make it enforceable, and the remaining provisions shall continue in full force and effect.

No waiver by cueball of any term or condition in these Terms shall be deemed a continuing waiver of such term or condition or a waiver of any other term or condition. Any failure by cueball to enforce a right or provision of these Terms shall not constitute a waiver of that right or provision.

20. Entire agreement

These Terms, together with the Privacy Policy and any applicable order form or enterprise agreement, constitute the entire agreement between you and cueball with respect to the Service and supersede all prior and contemporaneous understandings, agreements, representations, and warranties, both written and oral, with respect to the Service.

Section headings are for convenience only and shall not affect the interpretation of these Terms.

21. Changes to these terms

We reserve the right to modify these Terms at any time. The “Last updated” date at the top of this page indicates when the Terms were last revised.

For material changes, we will provide at least 14 days' advance notice via email and/or a prominent notice on the Service. Non-material changes (such as clarifications, formatting corrections, or updates to contact details) may be made without prior notice.

Your continued use of the Service after the effective date of any revised Terms constitutes your acceptance of those Terms. If you do not agree to the revised Terms, you must stop using the Service before the effective date.
