Terms of Service

These terms are a legal agreement between you and Transport Technical Innovation Ltd(“we”, “us”, “our”) and govern your use of BrakeGuard— the BrakeGuard mobile app, the licence and results service behind it, and the ttil.net website and customer portal (together, the “Service”). By installing the app, signing in to the portal, or using the Service, you agree to these terms. If you are agreeing on behalf of an organisation, you confirm you have authority to bind it, and “you” means that organisation.

1. The Service

BrakeGuardturns a phone or tablet into a brake-performance measurement aid. It measures deceleration from the device’s own sensors, records each test as a tamper-evident result, and can submit that result for attestation and for the production of a certificate. The Service supports UK DVSA brake-test workflows; it is a measurement and record-keeping tool, subject to the important limits in section 6.

2. Accounts and eligibility

Portal access is by sign-in through a third-party provider (for example Google). New accounts are held for approval and see nothing until an administrator approves and assigns them. Access is role-based, and each customer can see only its own data. You must give accurate information, keep your sign-in secure, and are responsible for activity under your account. The Service is for business and occupational use and is not intended for consumers or for children.

3. Licences and devices

Use of the app is governed by a licence code bound to a limited number of devices. Each licensed install receives a cryptographically signed licence envelope that authorises it for a bounded period; the app verifies that signature on every use. You must not:

• share a licence, or use it on more devices than your allowance permits;
• tamper with, forge, or extend a licence envelope or a signed result; or
• attempt to bypass device binding, expiry, or revocation.

We may suspend or revoke a licence for breach of these terms, misuse, or non-payment. Revocation takes effect within a bounded period even on a disconnected device.

4. Acceptable use

You agree not to:

• reverse-engineer, or attempt to defeat, the attestation and signing mechanism;
• submit false, altered, or misattributed test data;
• use the Service unlawfully, or to infringe anyone’s rights;
• probe, scan, overload, or disrupt the Service or its security controls; or
• use the Service to build a competing product, or in breach of the software licence it is provided under.

5. Your responsibilities for test data

You are responsible for the vehicle, operator, and test details you enter, for operating the device correctly (including mounting and calibration), and for ensuring you have the right to record and upload the data you submit — including telling the individuals concerned (such as drivers) where that is required. Test results are stored as append-only records once a test completes.

6. Regulatory context — important

BrakeGuard is a measurement aid, not a certifying authority. Using it does not by itself grant DVSA, MOT, or any other regulatory approval or certification. Whether a result is admissible for a regulated purpose depends on factors including correct and current calibration, the device’s sensor capability, and the rules of the relevant authority — and a result that does not meet those conditions is recorded but marked as not valid for regulated acceptance.

A result — including a pass — is a measurement of braking performance at the time of the test. It is not a warranty or determination that a vehicle is safe or roadworthy, and it does not replace your own professional judgement or any other inspection the vehicle requires. You must not present a result to any third party (such as a regulator, customer, or insurer) as conferring a certification or approval it does not carry.

You remain responsible for meeting your own statutory testing obligations and for exercising professional judgement. The Service does not replace a legally-required inspection, a qualified examiner, or approved testing equipment where those are mandated. Always follow the applicable DVSA / testing-scheme rules. [REVIEW: confirm this wording against the DVSA brake-test scheme.]

7. Privacy and data protection

Our handling of personal data is described in our Privacy Policy. For personal data contained in the brake-test records your devices upload, we act as your processor and you are the controller; where a separate customer or data processing agreement applies, that agreement governs that processing. [REVIEW: reference the DPA / customer agreement if one exists.]

8. Intellectual property

The Service — including the app, the portal, the attestation and signing mechanism, and all associated software and trade marks — is owned by us or our licensors and is protected by law. We grant you a limited, non-exclusive, non-transferable right to use the Service in accordance with these terms and your licence for its duration. You keep ownership of the test data you submit; you grant us the rights needed to host, process, and store it to provide the Service. If you send us feedback, we may use it without obligation to you.

9. Availability and changes

We aim to keep the Service available but do not guarantee uninterrupted or error-free operation unless a separate service-level agreement says so. We may update, add, or withdraw features, and may carry out maintenance. We will take reasonable steps to limit disruption.

10. Warranties and disclaimers

To the fullest extent permitted by law, the Service is provided “as is”and “as available”, and we exclude all implied warranties. In particular, we do not warrant that a measurement will be error-free, or that any result will satisfy a regulatory requirement — accuracy depends on correct use, device sensors, and valid calibration, which are your responsibility (sections 5 and 6). Nothing in this section limits the rights you have that cannot be excluded by law.

11. Liability

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 under the law of England and Wales.

Subject to that, we are not liable for indirect or consequential loss, loss of profit, revenue, goodwill, or data, or for any loss arising from your reliance on a result for a regulated purpose contrary to section 6. Our total liability arising out of or in connection with the Service is limited to [REVIEW: liability cap — e.g. the fees paid in the preceding 12 months, or a stated sum].

12. Indemnity

You agree to indemnify us against claims and losses arising from your misuse of the Service, your breach of these terms, or the data you submit (including any claim that it was collected or uploaded without the necessary rights or notices). [REVIEW: confirm scope of indemnity.]

13. Suspension and termination

We may suspend or terminate your access for a material breach of these terms, misuse, non-payment, or where required by law. You may stop using the Service at any time. On termination your right to use the Service ends; provisions that by their nature should survive (including sections 6, 8, 10–12, and 15) continue. Retention and erasure of your data are handled as described in the Privacy Policy.

14. Changes to these terms

We may update these terms from time to time. When we make a material change we will update the effective date and, where appropriate, notify you through the portal. Continuing to use the Service after a change takes effect means you accept the updated terms.

15. Governing law and jurisdiction

These terms and any dispute arising from them are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.
