AUTO PRINCESS LTD
TERMS OF SERVICE

Version 2.0  |  Last Updated: 28 June 2026

Effective Date: 28 June 2026

Registered Company Number: 17155826

IMPORTANT — PLEASE READ CAREFULLY. These Terms of Service form a legally binding agreement between you and Auto Princess Ltd. They contain important provisions relating to the limited and informational nature of the Software, restrictions on relying on AI-generated outputs for safety-critical decisions, your subscription and payment obligations, your right to cancel, and the limitation of our liability. Nothing in these Terms removes or limits your statutory rights as a consumer, including your rights under the Consumer Rights Act 2015. If you do not agree to these Terms, you must not download, install, access, or use the Software.

1. About These Terms and Who We Are

These Terms of Service ("Terms") govern your access to and use of the Auto Princess mobile application, the website at https://autoprincess.com, and all associated services, features, and content (together, the "Software" or "Services").

The Software is operated by Auto Princess Ltd ("Auto Princess", "we", "us", "our"), a company registered in England and Wales under company number 17155826, with its registered office at 71-75 Shelton St, London WC2H 9JQ. You can contact us at any time at support@autoprincess.com.

By creating an account, downloading, installing, accessing, or otherwise using the Software, you confirm that you accept these Terms and agree to comply with them. These Terms should be read together with our Privacy Policy, which explains how we collect and process your personal data and forms part of your agreement with us.

These Terms are provided in English. We may provide translations for convenience, but the English version prevails in the event of any inconsistency.

2. Definitions

3. Eligibility and Account Registration

By using the Software, you represent and warrant that you are at least 18 years of age, that you have the legal capacity to enter into a binding contract, and that you will use the Software in compliance with these Terms and all applicable laws.

You are responsible for maintaining the confidentiality of your Account credentials and for all activity that occurs under your Account. You must notify us promptly at support@autoprincess.com if you become aware of any unauthorised use of your Account. We authenticate Accounts using Firebase Authentication, and you may register using email and password, Google Sign-In, or Sign in with Apple.

You agree to provide accurate and current information when registering and to keep that information up to date. You must not impersonate any person or misrepresent your identity or affiliation.

4. Nature of the Service

The Software provides software-based vehicle diagnostic and information tools, which may include:

The Software is a consumer information and convenience tool. It is not a substitute for inspection, diagnosis, or advice from a qualified mechanic, engineer, or other professional.

5. Informational Use Only — No Professional Advice

The Software does not provide professional mechanical, engineering, safety, or certification advice. All AI Outputs and diagnostic results are informational, probabilistic, and provided to assist you — not to replace professional judgement. You must not rely solely on the Software when making decisions about vehicle safety, repairs, maintenance, roadworthiness, or vehicle purchases.

In particular, the Software does not provide, and must not be relied upon as, a guarantee that a vehicle is safe, roadworthy, free from defects, or fit for any particular purpose. You should always confirm any diagnostic finding with a qualified professional before acting on it, especially where safety is involved.

Nothing in this Section limits our 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 applicable law (see Section 18).

6. Artificial Intelligence — Limitations and Disclaimer

The Software uses artificial intelligence and machine learning systems, including third-party AI services such as Google Gemini, to generate diagnostic insights. You acknowledge and understand that:

To the fullest extent permitted by law, and subject to your statutory rights in Section 17, we do not warrant the accuracy, reliability, or completeness of any AI Output. You use AI Outputs at your own discretion and risk, and you remain responsible for verifying them with a qualified professional.

7. OBD-II and Vehicle Data

The Software integrates with third-party OBD-II adapters (such as ELM327-based devices) which we do not manufacture or supply. You acknowledge that:

Subject to your statutory rights and Section 18, we are not liable for incorrect readings, missed faults, or issues arising from hardware that we did not supply or from third-party data sources.

8. Acceptable Use and Safety

You agree to use the Software responsibly and lawfully. You must not:

SAFETY-CRITICAL RESTRICTION: The Software must never be used as the sole basis for any decision affecting the safety of a vehicle, its occupants, or other road users. Always operate your vehicle safely and lawfully, and never interact with the application while the vehicle is in motion unless doing so through a lawful, hands-free, stationary, or passenger arrangement.

9. Subscriptions, Pricing, and Payment

9.1 Plans and Pricing

The Software is offered on a freemium basis. The Free Tier provides access to certain features at no cost. Premium features require a Pro Plan subscription. Our current Pro Plan pricing is:

All prices are stated in pounds sterling (GBP) and include any applicable VAT unless stated otherwise. We will always show the total price payable, including the billing frequency, before you complete your purchase. We may change our prices from time to time; any price change will not affect a Subscription period you have already paid for, and we will give you advance notice of any change before it takes effect, together with your right to cancel before the new price applies.

9.2 How Payment and the Paywall Work

When you subscribe to a Pro Plan, payment is processed by our payment provider, Stripe (Stripe Technology Europe Limited), through a secure checkout. We do not receive or store your full payment card details; these are handled directly by Stripe. Once your payment is confirmed by Stripe, our systems record your entitlement to Pro features.

Access to Pro features is controlled automatically by an entitlement system. When you attempt to use a Pro feature, our systems check whether your Account holds a current Pro entitlement. If it does, access is granted; if it does not, you will be shown information about how to subscribe. This automated check is necessary to deliver the Subscription you have purchased. You may request a human review of any entitlement decision by contacting support@autoprincess.com.

9.3 Automatic Renewal

Subscriptions renew automatically at the end of each billing period (monthly or annually, as applicable) at the then-current price, unless you cancel before the renewal date. By subscribing, you authorise us and our payment provider (or the relevant Platform, where billing is handled by Apple or Google) to charge the applicable fee for each renewal period using your chosen payment method.

We will provide clear information about renewal at the point of purchase. Where required by applicable law, we will also send you reminder notices in advance of renewal. You can cancel auto-renewal at any time as described in Section 10.

9.4 Platform Billing

Where you purchase or manage a Subscription through the Apple App Store or Google Play Store, that purchase may be processed through the Platform's in-app purchase or billing system and is also subject to the Platform's own terms. In those cases, billing, renewals, and cancellations may be managed through your Apple ID or Google account settings, and the Platform's refund policies apply in addition to these Terms.

10. Your Right to Cancel and Cooling-Off Period

10.1 14-Day Cooling-Off Right

If you are a Consumer, you have a legal right under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 to cancel your Subscription within 14 days of entering into it, without giving any reason (the "Cooling-Off Period").

10.2 Immediate Access and Effect on the Cooling-Off Right

Because the Software provides digital content and digital services, you may ask us to begin providing the Pro features immediately, during the Cooling-Off Period. If you expressly request immediate access and acknowledge that you will lose your right to cancel once the service has been fully performed, then:

If you do not request immediate access, your Pro features will begin after the Cooling-Off Period ends, and you may cancel for a full refund within those 14 days.

10.3 How to Cancel

You may cancel your Subscription at any time and for any reason. Cancelling is as straightforward as subscribing. You can cancel by:

Consistent with applicable consumer law, our cancellation process does not require you to contact us by telephone, complete unnecessary steps, or take any action more difficult than the steps required to subscribe. Where you are an EEA-based Consumer, a clearly identifiable cancellation function is made available to you within the user interface.

When you cancel, your Pro entitlement will remain active until the end of the billing period you have already paid for, after which it will not renew and Pro features will revert to the Free Tier.

10.4 Refunds

Refunds for the Cooling-Off Period are handled as described in Section 10.2. Outside the Cooling-Off Period, Subscriptions are generally non-refundable except where required by law or where the Software has not been provided with reasonable care and skill or is not as described (see your statutory rights in Section 17). Where you purchased through a Platform, refunds may be requested and handled in accordance with that Platform's refund policy. This Section does not affect your statutory refund rights.

11. Your Content and AI Training Licence

11.1 Ownership of Your Content

You retain ownership of the Content you submit to the Software. We do not claim ownership of your raw Content.

11.2 Licence You Grant to Us

By submitting Content, you grant Auto Princess Ltd a worldwide, non-exclusive, royalty-free, sublicensable licence to host, store, reproduce, process, adapt, and use that Content for the purposes of operating, providing, securing, and improving the Software, including using Content to train, evaluate, and improve our artificial intelligence and machine learning models, as further described in our Privacy Policy.

In respect of personal data contained within your Content, our processing is also governed by our Privacy Policy and by applicable data protection law. Where Content is used for AI training, it is processed in accordance with the safeguards and lawful bases set out in our Privacy Policy, including anonymisation or pseudonymisation where appropriate.

This licence continues for as long as is necessary for the purposes described above. Where Content has been incorporated into trained AI models in anonymised form, the licence in respect of that anonymised, non-identifying material is perpetual and irrevocable, because such material can no longer be associated with you and cannot technically be removed from a trained model. This is explained further in Section 12 and in our Privacy Policy.

11.3 Your Warranties Regarding Content

You represent and warrant that you own or have the necessary rights to submit your Content and to grant the licence above, and that your Content does not infringe the rights of any third party or breach any applicable law.

12. AI Models, Derived Assets, and Irreversibility

All artificial intelligence models, trained datasets, model weights, and AI Outputs developed by us, including those trained or improved using Content, are and remain the exclusive intellectual property of Auto Princess Ltd. While you retain ownership of your raw Content, you do not acquire any ownership interest in our AI models or derived datasets.

IRREVERSIBILITY OF AI TRAINING: You acknowledge that, once Content has been used to train a machine learning model and has been anonymised as part of that process, it is not technically possible to identify or remove the influence of that specific Content from the trained model. Deleting your Account will remove your personal data from our live systems as described in our Privacy Policy, but cannot remove anonymised data from previously trained models. This limitation reflects the technical nature of machine learning and is consistent with guidance from the UK Information Commissioner's Office. Your data protection rights, and their limits, are set out in full in our Privacy Policy.

13. Our Intellectual Property

All intellectual property rights in the Software, including its source code, AI systems and models, user interface and design, graphics, algorithms, architecture, branding, and the "Auto Princess" name and logo, are owned by or licensed to Auto Princess Ltd and are protected by law.

We grant you a limited, non-exclusive, non-transferable, revocable licence to download and use the Software on a device you own or control, solely for your personal, non-commercial use (or, for Business Users, your internal business use), in accordance with these Terms and any applicable Platform rules. All rights not expressly granted to you are reserved.

You must not copy, modify, distribute, sell, lease, or create derivative works from any part of the Software, nor reverse engineer or attempt to extract our models or algorithms, except to the limited extent that applicable law expressly permits despite this restriction.

14. Third-Party Services and Platform Terms

14.1 Third-Party Services

The Software relies on third-party services, including cloud infrastructure (Google Firebase / Google Cloud), AI processing (Google Gemini), payment processing (Stripe), and government data services (DVLA and DVSA). Your use of features that depend on these services may also be subject to those providers' own terms and privacy policies. We are not responsible for the acts, omissions, availability, or policies of third-party providers, except as required by law.

14.2 Apple App Store Terms

The following applies where you download the application from the Apple App Store. You acknowledge that:

14.3 Google Play Store Terms

Where you download the application from the Google Play Store, your use is also subject to the Google Play Terms of Service. Auto Princess, not Google, is responsible for the Software and for any support, and Google is not liable for the Software or your use of it, to the extent permitted by applicable law.

15. Privacy and Data Protection

Our collection and use of personal data is governed by our Privacy Policy, which forms part of these Terms and is available at https://autoprincess.com. By using the Software, you acknowledge that our Privacy Policy describes how your data is processed, including its use for AI training (subject to the safeguards stated there), our data retention practices, and any international transfers of data. We process personal data in accordance with the UK GDPR and, where applicable, the EU GDPR.

16. Service Availability

We work to keep the Software available and functioning, but we do not guarantee that it will be uninterrupted, error-free, secure, or compatible with every device, operating system version, or vehicle. We may suspend, withdraw, or restrict the availability of all or part of the Software for business or operational reasons, and we will give you reasonable notice where we can.

Subject to your statutory rights in Section 17, the Software is otherwise provided on an "as available" basis.

17. Your Statutory Rights as a Consumer

Nothing in these Terms affects your legal rights as a Consumer. If you are a Consumer, you have statutory rights that we cannot exclude or limit.

If you are a Consumer based in the United Kingdom, the Consumer Rights Act 2015 gives you statutory rights in relation to digital content and services we supply. In particular, digital content and services must be of satisfactory quality, fit for a particular purpose made known to us, and as described. If digital content or a service we supply is faulty or not as described, you may be entitled to a repair, a replacement, a price reduction, or a refund, as provided by law. We will not seek to exclude or limit these rights, and any provision in these Terms is to be read subject to them.

If you are a Consumer based in the EEA, you benefit from the mandatory consumer protections of the law of your country of habitual residence, including under the EU Consumer Rights Directive, the Digital Content Directive, and the Unfair Contract Terms Directive. Nothing in these Terms deprives you of those protections.

For more information about your statutory rights, UK Consumers can contact the Citizens Advice consumer service, and EEA Consumers can contact their local consumer advice body.

18. Limitation of Liability

Nothing in these Terms excludes or limits 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; for breach of the statutory rights described in Section 17; or for any other liability that cannot be excluded or limited under applicable law.

18.1 If you are a Consumer

We are responsible for loss or damage you suffer that is a foreseeable result of our breach of these Terms or our failure to use reasonable care and skill, but we are not responsible for any loss or damage that is not foreseeable. Loss or damage is foreseeable if either it is obvious that it will happen, or if, at the time you accepted these Terms, both we and you knew it might happen.

Because the Software is supplied for domestic and private use, we do not accept liability for any loss of profit, loss of business, business interruption, or loss of business opportunity. We will not be responsible for damage to a vehicle or other property that you could have avoided by following our advice to verify AI Outputs with a qualified professional, or that was caused by your failure to do so, except to the extent such damage results from our own failure to use reasonable care and skill.

18.2 If you are a Business User

Subject to the opening paragraph of this Section, our total aggregate liability to a Business User arising out of or in connection with these Terms, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, shall not exceed the greater of: (a) the total fees paid by that Business User to us in the 12 months preceding the event giving rise to the claim; or (b) one hundred pounds (£100). We exclude all liability to Business Users for indirect or consequential loss, loss of profits, loss of data, and loss of goodwill, to the fullest extent permitted by law.

19. Indemnity

If you are a Business User, you agree to indemnify and hold us harmless against any losses, damages, liabilities, and reasonable costs we incur arising from your breach of these Terms, your unlawful use of the Software, or your infringement of any third-party right.

If you are a Consumer, you are responsible for losses we suffer caused by your breach of these Terms, your deliberate misuse of the Software, or your breach of applicable law, where such loss was a foreseeable consequence of your actions. We do not require Consumers to provide a general indemnity, and this Section is to be read consistently with your statutory rights and the limitations on consumer liability under applicable law.

20. Suspension and Termination

You may stop using the Software and close your Account at any time.

We may suspend or terminate your access to the Software, or close your Account, where: you have materially breached these Terms; we are required to do so by law or a regulatory authority; we reasonably suspect fraudulent, unlawful, or abusive use; or it is necessary to protect the security or integrity of the Software or other users.

Except where we are prevented by law, where the breach is incapable of remedy, or where immediate action is necessary to prevent harm, we will give you reasonable notice before suspending or terminating your access, will tell you the reason, and will give you an opportunity to put matters right where appropriate.

On termination, your right to use the Software ends. You may, before termination takes effect or within a reasonable period afterwards, request a copy of your Content and data in a portable format as described in our Privacy Policy. Sections of these Terms which by their nature should survive termination (including Sections 11 to 13 and 17 to 26) will continue to apply.

21. Changes to These Terms

We may update these Terms from time to time, for example to reflect changes in the Software, in our business, or in legal or regulatory requirements.

For minor or non-material changes, we will update the "Last Updated" date at the top of these Terms. For material changes that affect your rights or obligations, we will give you reasonable advance notice by in-app notification, by email to your registered address, or by a prominent notice on our website, before the change takes effect.

If you do not agree to a material change, you may cancel your Subscription and stop using the Software before the change takes effect; if you continue to use the Software after a material change takes effect, you will be treated as having accepted it. Where the change requires your consent under applicable law, we will obtain that consent rather than relying on continued use. This Section does not limit your statutory rights, including any right to terminate without penalty.

22. Complaints and Dispute Resolution

If you have a complaint or a dispute, please contact us first at support@autoprincess.com so that we can try to resolve it. We aim to acknowledge complaints promptly and to work with you in good faith towards a resolution.

If we cannot resolve the dispute between us, you may be entitled to refer it to an alternative dispute resolution (ADR) provider. ADR is a way of resolving disputes that does not involve going to court. If we are unable to resolve a dispute through our internal complaints process, we will, where required, inform you whether we agree to use a particular ADR provider.

Important: Nothing in these Terms requires a Consumer to submit to binding arbitration, and nothing prevents a Consumer from bringing proceedings in the courts. As a Consumer, you retain the right to bring a claim in the courts of your country of residence, and to rely on the mandatory consumer protection laws of that country.

For Business Users only, any dispute that cannot be resolved through good-faith negotiation may, at the election of either party, be referred to arbitration in London under the rules of the London Court of International Arbitration (LCIA), conducted in English; this arbitration provision does not apply to Consumers.

23. Governing Law and Jurisdiction

These Terms, their subject matter, and their formation are governed by the law of England and Wales.

If you are a Consumer, you may bring legal proceedings in the courts of England and Wales, or in the courts of the part of the United Kingdom in which you live. If you live in Scotland, you may bring proceedings in the Scottish courts; if you live in Northern Ireland, in the Northern Irish courts. If you are an EEA-based Consumer, you may bring proceedings in the courts of your country of habitual residence, and you benefit from the mandatory protections of the law of that country, which are not overridden by the choice of English law in these Terms.

If you are a Business User, you and we agree that the courts of England and Wales have exclusive jurisdiction over any dispute, subject to the arbitration provision in Section 22.
