Terms of Service

The agreement between you and AVB RaceLabs for the website, the web portal and the mobile apps.

Last updated 9 October 2026

1. Who we are and what these terms cover

AVB RaceLabs is a trading name of Stride Innovations Limited, a company registered in England and Wales under company number 10823490 ("AVB RaceLabs", "we", "us").

These terms apply when you use any of our services:

  • the website at https://avbracelabs.com;
  • the web portal at https://portal.avbracelabs.com;
  • the AVB RaceLabs apps for iPhone, iPad and Android (the "apps");

together, the "Services". When you create an account we ask you to confirm your age and that you accept these terms; if you do not accept them, you cannot create an account. If you only visit our website, sections 7, 11 and 18 apply to you. These terms work alongside our Privacy Policy, our AI Policy and our Disclaimer, which form part of them. If you do not agree, please do not use the Services.

If you use the Services as a consumer, nothing in these terms affects your statutory rights.

2. Your account

  • Age. You must be 18 or over to hold an account in your own right. A young person aged 13 to 17 may hold an account only if a parent or guardian agrees to these terms. The parent or guardian then becomes a party to these terms alongside the young person, is responsible for the young person's use of the Services, and must make any purchase of a paid plan. Children under 13 may not hold an account; a parent, guardian or team can record a young driver's details in their own account instead, and is responsible for doing so.
  • Accurate details. Keep your account details accurate. Calculations depend on what you enter: kart, class, weights and tyres.
  • Security. Keep your sign-in details private. You are responsible for activity on your account. Tell us straight away through the contact form if you think someone else has used it.
  • One person per account. Accounts are personal and must not be shared or transferred.

3. The Services

The Services help karting drivers, parents, mechanics and teams plan and record their racing. They include:

  • engineering baselines for tyres, gearing, setup, grip and ballast, worked out from your kart, class, track and weather data;
  • the Pit Kit: calculators, checklists, libraries and season journals, most of which work offline on your phone;
  • AI features, including the AI Race Engineer chat, AI insights and the AI Tyre Condition reader (see section 8 and our AI Policy);
  • team tools for managers and members;
  • the web portal, for plans that include it.

Guidance, not instructions. Everything the Services produce, including calculations, baselines, predictions and AI answers, is guidance to help you make your own decisions. It is not professional engineering advice, and it does not replace your own judgement, a qualified mechanic, or the rules of your championship, club, circuit or governing body. Please read our Disclaimer.

We keep developing the Services, so features may be added, changed or withdrawn. We will not remove a feature that is a main part of a paid plan you are on without telling you at least 30 days in advance. You can then cancel, and we will refund any amount you have paid for the period after the change.

4. Plans and payment

  • Plans. We offer Free, Premium and Pro with AI plans for individuals, and team bands (Crew, Team and Works) priced by the number of drivers. A driver on a team with a band can take a discounted member plan, with an optional AI top-up, once the team manager approves it; if the driver leaves the team or the band ends, the member plan runs to the end of the month. What each plan includes is described on our Pricing page at the time you choose it.
  • Plans offered free of charge. If a plan is available free of charge for a period, no payment is taken. Before we start charging for a plan you are on, we will tell you at least 30 days in advance and ask you to confirm; nothing changes until you do.
  • Price changes. Where a plan is charged, we will show you the price before you pay. If we change the price of a plan you are on, we will tell you at least 30 days before the change applies, and you can cancel before it does.
  • Where you pay. Paid plans can be bought through the App Store, Google Play or directly from us, as shown when you buy. Apple and Google bill and renew purchases made through them and handle refunds of the price. This does not affect your rights against us under the Consumer Rights Act 2015 if a feature is faulty or not as described.
  • Renewal and cancellation. Paid plans renew automatically at the end of each billing period, as shown when you buy, until you cancel. For App Store and Google Play purchases, payment is charged to your store account when you confirm, and the plan renews unless you turn off auto-renew at least 24 hours before the period ends. To cancel a plan bought from us, use the app's settings, the portal or the contact form. Your plan stays active until the end of the period you have paid for and then moves to Free. Moving to Free does not delete your data: some limits apply again and paid features are locked, but you can still open what you have saved, and you can ask us for a copy of anything saved to your account.
  • Your right to cancel. If you are a UK consumer and buy a paid plan directly from us, you can cancel within 14 days by telling us through the contact form. You may use the model cancellation form, but you do not have to. We will refund you within 14 days of being told, to the payment method you used. If you expressly asked us to start your plan straight away, we may deduct a proportionate amount for the days before you cancelled. Purchases through Apple or Google are refunded through them.
  • Faulty digital content. If a paid feature is faulty or not as described, you have rights under the Consumer Rights Act 2015, including repair, replacement or a refund.

5. Teams

  • Managers. A team manager can create a team, invite and approve members, and manage team assets, calendar, entries, workshop jobs and invoicing. The manager is responsible for having the team's permission to hold and share its members' information within the team, and for any team plan the team buys.
  • Members. When you join a team, the team's members and manager can see the information you share with the team, as described in our Privacy Policy. You can leave a team at any time.
  • Invoicing between teams and drivers. Team invoicing lets a team bill its own drivers. Any charge is an arrangement between the team and the driver. We are not a party to it, do not handle the money, and take no commission. Disputes about those charges are between the team and the driver.

6. Your content

"Your content" means everything you put into the Services: sessions, setups, notes, journals, photos, messages to the AI Race Engineer and team records.

  • You own your content.
  • You give us a non-exclusive, worldwide, royalty-free licence to host, store, copy, process and display your content only as needed to provide, secure and improve the Services for you, and to share it with the people you choose, such as your team. The licence ends when your content is deleted, except for copies we must keep by law or that remain for a short time in backups.
  • You are responsible for having the right to upload your content, including photos and other people's details.
  • We may use aggregated information that cannot identify you or anyone else to understand and improve the Services.

7. Acceptable use

You must not:

  • use the Services while driving or operating a kart, or in any way that distracts you or anyone else on track;
  • break the law, or the rules of any circuit, club or governing body, using the Services;
  • upload content that is unlawful, harmful, abusive, or infringes someone else's rights, or personal information about other people without a lawful reason;
  • try to get around plan limits, AI usage limits or security measures, or access another person's account or data;
  • copy, scrape, resell, reverse-engineer or create a competing product from the Services, our track library or our data, except where the law allows;
  • use automated systems, bots or scripts to access the Services, except through features we provide for that purpose;
  • disrupt or overload the Services, or introduce malicious code;
  • use the AI features to produce content unrelated to karting, or to try to make them produce harmful, misleading or unlawful output.

8. AI features

Some features use artificial intelligence (AI). By using them you agree to our AI Policy. In particular:

  • AI answers are generated automatically, are labelled as AI-generated, and can be wrong, incomplete or out of date. Check any AI answer before you act on it, especially anything affecting safety, legality or eligibility.
  • The AI Race Engineer is limited to karting topics and is subject to a usage allowance.
  • You are responsible for what you ask, for any photos you submit, and for how you use the answers.
  • We may change the AI providers and models we use, or limit or suspend AI features, to keep them safe, lawful and reliable.

9. Safety

Karting is a dangerous activity. You remain fully responsible for your kart, every adjustment made to it, how you drive it, and your compliance with the regulations that apply to you. Never use the Services while driving. Our Disclaimer explains this in more detail.

10. Availability and changes

We aim to keep the Services available and secure, but we do not promise they will be uninterrupted or error-free. Online features need an internet connection; many Pit Kit tools work offline. We may suspend the Services for maintenance, security or reasons outside our control. Track, weather and other third-party data may be incomplete or inaccurate.

11. Our intellectual property

The Services, including the software, design, track library, calculations, content, names and logos, belong to us or our licensors and are protected by intellectual property laws. We give you a personal, non-exclusive, non-transferable, revocable licence to use the Services for your own karting under these terms. We reserve all other rights.

Feedback and suggestions you send us may be used freely, without any obligation to you.

12. Third-party services

The Services rely on, or link to, services run by others, such as app stores, sign-in providers, weather and mapping data, and AI providers. Their own terms and privacy policies apply to your use of them, and we are not responsible for their content or availability.

13. Mobile app terms (Apple and Google)

If you download the apps from the Apple App Store or Google Play:

  • these terms are between you and us only, not with Apple or Google, and we, not Apple or Google, are responsible for the apps and their content;
  • your use of the apps must also follow the app store's usage rules, and your licence to use the iOS app is limited to Apple-branded devices you own or control, as the Usage Rules permit, except that other accounts linked to you through Family Sharing may also use it;
  • Apple and Google have no obligation to provide maintenance or support for the apps;
  • if an app fails to meet any applicable warranty, you may notify Apple, and Apple may refund the purchase price of the app (if any); to the maximum extent permitted by law, Apple has no other warranty obligation for the apps;
  • we, not Apple or Google, are responsible for handling any claims relating to the apps, including product liability claims, claims that the apps fail to meet legal or regulatory requirements, and consumer protection or privacy claims;
  • if a third party claims that the apps or your use of them infringe their intellectual property rights, we, not Apple, are responsible for the investigation, defence, settlement and discharge of that claim;
  • you must comply with any third-party terms that apply when you use the apps, such as your mobile data agreement;
  • you confirm that you are not located in a country subject to a US Government embargo or designated by the US Government as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties;
  • Apple and its subsidiaries are third-party beneficiaries of these terms and, once you accept them, may enforce them against you as a third-party beneficiary.

14. Suspension, termination and deleting your account

  • You can stop using the Services at any time. You can delete your account in the app (Settings, then Delete account), in the web portal, or without the app by following our account deletion page. Deleting your account deletes your content as described in our Privacy Policy. Cancel any app store subscription separately with Apple or Google.
  • We may suspend or close your account if you seriously or repeatedly break these terms, if we must do so by law, or to protect other users or the Services. Where reasonable, we will warn you first and give you a chance to ask us for a copy of your content. If we close your account for a reason other than your serious or repeated breach of these terms, we will refund any amount you have paid for the period after closure.
  • If we stop providing the Services altogether, we will give you reasonable notice and refund any amount you have paid us for a period you will not receive.

Sections 6, 11, 15, 17 and 18 continue to apply after these terms end.

15. Our responsibility to you

What we do not exclude. Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot be limited or excluded by law, including your statutory rights as a consumer.

If you are a consumer:

  • We are responsible for loss or damage you suffer that is a foreseeable result of our breaking these terms or failing to use reasonable care and skill. We are not responsible for loss or damage that is not foreseeable.
  • If defective digital content we supplied damages a device or other digital content of yours, and this is caused by our failure to use reasonable care and skill, we will either repair the damage or pay you compensation.
  • The Services are for domestic and private use. We are not liable to you for any loss of profit, loss of business, business interruption, or loss of business opportunity.
  • We are not responsible for the outcome of decisions you make using the Services, such as setup changes, race results, prize money, or damage to karts and equipment, unless that loss is caused by our breach of these terms or our negligence and was foreseeable.

If you use the Services for business (for example, a team or professional outfit):

  • we exclude all implied conditions, warranties and terms to the extent the law allows;
  • we are not liable for loss of profit, revenue, business, goodwill or data, or for any indirect or consequential loss; and
  • our total liability arising out of or in connection with these terms in any 12-month period is limited to the greater of £100 and the fees you paid us for the Services in that period.

16. Changes to these terms

We may update these terms, for example to reflect changes to the Services or the law. We will post the new version here with a new date. If a change materially affects you, we will tell you in the apps, the portal or by email at least 30 days before it takes effect. Continuing to use the Services after the change takes effect means you accept the new terms; if you do not, you can close your account. We will change these terms only for a valid reason, such as a change in the law or in the Services, or to correct an error. If you close your account because a change is to your disadvantage, we will refund any amount you have paid for the period after you close it.

17. Complaints and disputes

If you have a complaint, please tell us through the contact form and we will try to resolve it quickly. If you are a consumer, you can also contact Citizens Advice, and you may be able to take a claim to court.

18. Governing law

These terms are governed by the law of England and Wales. You and we both agree that the courts of England and Wales have jurisdiction, except that if you are a consumer living in Scotland or Northern Ireland you may also bring proceedings in your home courts.

19. General

  • If any part of these terms is found to be unenforceable, the rest stays in effect.
  • If we do not enforce a right straight away, we can still enforce it later.
  • We may transfer our rights and obligations under these terms to another organisation; we will tell you, and it will not affect your rights. You may not transfer yours without our written consent.
  • Apart from Apple (section 13), no one other than you and us has any right to enforce these terms.
