Terms of Service

Last updated: 8 June 2026

These Terms of Service ("Terms") are a legal agreement between you and us. They govern your access to and use of the Jitsunami+ platform, websites, mobile apps, and related services (together, the "Platform").

By creating an account, ticking the box that says you accept these Terms, or otherwise accessing or using the Platform, you agree to these Terms and to our Privacy Policy, Acceptable Use Policy, and Cookie Policy, which are incorporated into these Terms by reference. If you do not agree, do not use the Platform.

Please read section 11 (Service provided "as is"), section 12 (Data, backups and security), section 13 (Limitation of liability), and section 14 (Acknowledgement and acceptance of risk) carefully. They limit our liability to you and allocate important risks.

1. Who we are

Jitsunami+ is operated by Aptitude Agency Ltd (company number 6922078), a company registered in England and Wales whose registered office is at Bedford iLab, Stannard Way, Bedford, MK44 3RZ, United Kingdom. Our VAT registration number is 175581971. In this document, "we", "us", "our" and "Jitsunami+" mean Aptitude Agency Ltd.

Jitsunami+ is software that helps Brazilian Jiu-Jitsu academies run their operations: managing members, schedules, attendance, belt progression, payments, communications, and an optional AI Assistant. We provide the software. We do not run any academy, deliver any classes, or supervise any training.

2. Definitions

  • "Academy" (or "Club") means a martial arts business that subscribes to the Platform to manage its operations.
  • "Customer" means the Academy that holds the paid subscription. The Customer is responsible for its own use of the Platform and for the people it gives access to.
  • "User" means any person who accesses the Platform, including Academy owners, staff, coaches, reception, members, and the parents or guardians of members.
  • "Member" means a person who trains at, or is enrolled with, an Academy and whose details are managed on the Platform.
  • "Content" means any data, text, images, files, or other material uploaded to or generated on the Platform.
  • "Subscription" means a paid plan that gives an Academy access to the Platform.

3. The service

We grant each User a limited, non-exclusive, non-transferable, revocable right to access and use the Platform for its intended purpose: running or participating in a Brazilian Jiu-Jitsu academy, in accordance with these Terms.

The Platform is for Brazilian Jiu-Jitsu academy management. It is not designed for, and we do not support, use as a general-purpose payment processor, a marketing or lead-generation tool, a point-of-sale or merchandise system, a video curriculum library, or for any non-martial-arts business. We may add, change, or remove features at any time.

4. Your account and eligibility

To use most features you need an account. You agree to provide accurate information and to keep it up to date. One person should hold one account, which may carry roles at one or more Academies.

You are responsible for keeping your login details confidential and for everything that happens under your account. Tell us promptly (by raising a support ticket) if you believe your account has been accessed without your permission.

You must be old enough to enter into a contract to hold your own account. Children below an Academy's age threshold do not hold their own login; a parent or guardian manages their participation and accepts these Terms on their behalf. By accepting these Terms as a parent or guardian, you confirm you have authority to do so for the child concerned.

5. Academies, members and responsibilities

Where you are an Academy (or act for one), you are responsible for how you use the Platform and for the people you give access to. In particular, you agree that:

  • You are the data controller for the personal data of your Members and staff that you collect, enter, or manage on the Platform. We act as a data processor, processing that data on your instructions to provide the Platform. This is explained further in our Privacy Policy.
  • You are responsible for having a lawful basis to collect and use your Members' data, for giving your Members any privacy information they are entitled to, and for obtaining any consents you need (including for minors and for any medical information).
  • You are responsible for the accuracy of the data you enter, for your own waivers, codes of conduct, and policies, and for your own decisions about belts, gradings, bookings, and discipline.
  • You are responsible for your own payment, pricing, and refund arrangements with your Members, and for any tax you owe.
  • You will not use the Platform in any way that breaks the law, infringes anyone's rights, or breaches the Acceptable Use Policy.

If you are a Member, parent, or guardian, your relationship for training, fees, medical matters, and discipline is with your Academy, not with us. We provide the software the Academy uses; we are not a party to your membership.

6. Subscriptions, billing and cancellation

Access to the Platform for an Academy is provided on a subscription. The price, billing frequency, and any free-trial period are those shown to you at the point of sign-up or as we otherwise notify you. We may offer a free trial; at the end of the trial your Subscription continues at the then-current fee unless you cancel before the trial ends.

Unless stated otherwise:

  • Subscription fees are billed in advance for each billing period and are payable through the payment method you provide.
  • You can cancel at any time. Cancellation takes effect at the end of your current paid period, and you keep access until then.
  • Fees already paid are non-refundable, and we do not give refunds or credits for partial periods, downgrades, or unused time, except where the law requires otherwise.
  • We may change our fees. If we do, we will give you reasonable notice, and the change will apply from your next billing period. If you do not agree to a change, your remedy is to cancel before it takes effect.
  • If a payment fails or is overdue, we may suspend or limit your access until it is paid.

Fees are stated exclusive of any applicable taxes unless we say otherwise, and you are responsible for any such taxes.

7. Member payments and the academy's payment provider

Where Members pay an Academy through the Platform, those payments are processed by the Academy's own connected payment provider (for example, Stripe) and flow directly to the Academy. We are not the merchant, seller, or recipient of those payments, and we do not hold Members' money.

Any dispute about a membership fee, drop-in fee, refund, chargeback, or other Member payment is between the Member and the Academy. We are not responsible for it and are not obliged to refund or resolve it. The Academy's chosen payment provider has its own terms, which apply to those payments.

We never see or store full card numbers. Card details are handled by the payment provider's secure systems.

8. Acceptable use

You must use the Platform lawfully and decently. Our Acceptable Use Policy sets out what is not allowed and forms part of these Terms. Breaking it is a breach of these Terms and may lead to suspension or termination.

9. AI Assistant

The Platform may include an AI Assistant. It is a convenience tool that generates responses automatically and can be wrong, incomplete, or out of date.

  • AI responses are not professional advice. Do not rely on them for legal, medical, financial, safety, or other important decisions. Always use your own judgement and check anything that matters.
  • We are not liable for any decision you make, or action you take or do not take, based on AI output.
  • You must not use the AI Assistant to try to access data outside your own permissions, to extract another Academy's data, or in any way that breaches the Acceptable Use Policy.

10. Intellectual property and your content

We (and our licensors) own the Platform and all intellectual property rights in it, including the software, design, and branding. Nothing in these Terms transfers those rights to you. You may not copy, modify, reverse-engineer, resell, or create derivative works from the Platform except to the limited extent the law does not allow us to prevent.

You keep ownership of your Content. By using the Platform, you grant us a worldwide, non-exclusive, royalty-free licence to host, store, copy, transmit, display, and process your Content as needed to provide, secure, and improve the Platform and to comply with the law. You confirm you have the rights needed to upload your Content and to grant this licence.

11. Service provided "as is"

The Platform is provided "as is" and "as available". To the fullest extent the law allows, we make no warranties, conditions, or representations 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 Platform will be uninterrupted, timely, secure, error-free, or free of viruses or other harmful components, that any defect will be corrected, or that the Platform will meet your requirements. Jitsunami+ is an evolving, early-stage service, and features may change, be suspended, or be discontinued at any time.

We do not guarantee any level of availability or uptime. We may carry out maintenance, updates, or changes that make the Platform temporarily unavailable, and we will try, but are not obliged, to give notice.

12. Data, backups and security

We take reasonable technical and organisational measures to protect the Platform and the data on it. However, no system, network, or method of transmission or storage is completely secure or guaranteed against failure, and we cannot and do not guarantee that data will never be lost, corrupted, accessed without authorisation, or destroyed.

You are responsible for keeping your own independent copies of any data that is important to you. Where the Platform offers an export feature, you should use it regularly. To the fullest extent the law allows, we are not liable for any loss, corruption, or unauthorised access to data, beyond the protections that data protection law does not allow us to exclude.

Nothing in this section reduces the data protection obligations we owe under applicable law, which are explained in our Privacy Policy.

13. Limitation of liability

Nothing in these Terms limits or excludes our liability where it would be unlawful to do so. This includes liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, and for anything else that cannot be limited or excluded under the law (including certain rights you may have under data protection law).

Subject to that, and to the fullest extent the law allows:

  • We are not liable for any indirect, special, or consequential loss, or for any loss of profits, revenue, business, anticipated savings, goodwill, opportunity, or data, however it arises and even if we were told it might happen.
  • We are not liable for any loss or damage arising from: any unavailability, interruption, delay, or failure of the Platform; any loss, corruption, or unauthorised access to data, except as set out in section 12; your reliance on the Platform or on AI output; the acts or omissions of any Academy, Member, or other User; or any third-party service.
  • Our total liability to you for all claims arising out of or connected with the Platform and these Terms, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, is limited in aggregate to the greater of: (a) the total fees you paid to us in the 12 months before the event giving rise to the claim; or (b) 100 pounds sterling (GBP 100).

Where you use the Platform as a business, you also agree that the implied terms and remedies of consumer law do not apply to you, to the extent the law allows. These limits reflect the price of the Platform and the allocation of risk between us, and you agree they are reasonable.

14. Acknowledgement and acceptance of risk

You understand and accept, as a condition of using the Platform, that:

  • the Platform may at times be unavailable, fail, or contain errors;
  • data may be lost, corrupted, or become inaccessible despite our safeguards;
  • security incidents, including unauthorised access or "hacking", can happen to any online service despite reasonable measures; and
  • you use the Platform on this basis and accept these risks.

You agree that, in return for being able to use the Platform on these terms and at this price, you accept the limitations of liability and the allocation of risk set out in these Terms.

15. Indemnity

You agree to indemnify and hold us harmless from and against any claims, demands, losses, liabilities, damages, costs, and expenses (including reasonable legal fees) arising out of or connected with: your use of the Platform; your Content; your breach of these Terms or of any law; and, where you are an Academy, your handling of your Members' data and your dealings with your Members.

16. Suspension and termination

We may suspend, limit, or terminate your access to the Platform, with or without notice, if you breach these Terms, if your payment is overdue, if we reasonably believe your use is unlawful or harmful, or if we are required to by law.

You may stop using the Platform at any time and, if you are an Academy, cancel your Subscription as set out in section 6. On termination, your right to use the Platform ends. Where reasonably practicable, we will give you a short window to export your data before it is deleted in the ordinary course, subject to our Privacy Policy and our legal obligations. Sections that by their nature should survive (including sections 10 to 15, 17, and 19) continue after termination.

17. Third-party services

The Platform relies on third-party services (for example, payment providers, hosting, email, and AI providers). Those services have their own terms and privacy policies, and we are not responsible for them or for any act or omission of those providers. Your use of a feature that depends on a third party may be subject to that third party's terms.

18. Changes to these Terms

We may update these Terms from time to time. When we make a material change, we will update the version and the "last updated" date and, where appropriate, ask you to accept the updated Terms before you continue to use the Platform. Your continued use after an update means you accept the updated Terms.

19. General

These Terms, together with the documents they refer to, are the entire agreement between you and us about the Platform and replace any earlier agreement on the same subject.

If any part of these Terms is found to be invalid or unenforceable, the rest continues to apply. If we do not enforce a right, that is not a waiver of it. You may not transfer your rights or obligations under these Terms without our consent; we may transfer ours as part of a reorganisation, sale, or similar event.

We are not liable for any failure or delay caused by events beyond our reasonable control. We may give you notices through the Platform, in-app, or by post. These Terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction, except that if you deal with us as a consumer you may also have the benefit of mandatory protections of the country where you live.

20. How to contact us

You can reach us in either of these ways:

  • Support tickets. If you have a Jitsunami+ account, open a support ticket from within the Platform. This is the quickest way to reach us and lets us link your request to your account.
  • By post. Write to us at Aptitude Agency Ltd, Bedford iLab, Stannard Way, Bedford, MK44 3RZ, United Kingdom.

We do not provide support by email. Please raise a support ticket or write to us by post so that we can handle your request properly.
