Terms of Service

These terms apply to you as an individual when you use TFA — Technician Field Assistant — in a web browser or as the TFA app for iOS and Android. TFA is operated by Aspire USA LLC, doing business as Nexera ("Nexera"). Using TFA means you accept them.

These are not the agreement between Nexera and your employer. The dealership or service organization you work for has its own agreement covering pricing, ownership of its service data, how long that data is kept, service levels, and what either side owes the other commercially. That agreement governs all of it. Where it and this page address the same subject, that agreement controls and this page gives way. Nothing here adds to or reduces what your employer agreed to.

So this page does one job: it sets out what is expected of you while you are using the app, and what you can and cannot expect from it. It does not try to settle questions that belong to your employer's contract.

You cannot sign yourself up for TFA. Your employer creates your account using a work email address, decides what you are permitted to see, and closes it when it should be closed. You must be at least 18 and authorised by that organization to hold one.

Your sign-in is yours alone. Do not share your password, do not let someone else work under your account, and do not use anyone else's. If you think somebody has got hold of your credentials, tell your service manager and email us at the address below.

Work you do in TFA is attributable to your account, and your employer can see it. That is deliberate — a service manager is meant to be able to see how their team is using the tool.

Signing out ends your session. Note that deleting the app does not by itself end it: your session can remain valid until it expires or is revoked, so sign out if you are handing the device to somebody else.

TFA's assistant is generated by an AI model. It draws on your dealer's service history and on documentation in your library, and it is often useful — but it can be incomplete, out of date, or simply wrong, and it can state a wrong answer with confidence.

Treat what it tells you as a starting point, in the same way you would treat a colleague's suggestion over the radio. Before you act on it, check it against the manufacturer's service documentation and against what you can see on the machine.

You remain responsible for your own work: for the diagnosis you settle on, the parts you fit, the safety procedures you follow, and your compliance with the manufacturer's instructions and your employer's practices. Nothing the assistant says relieves you of professional judgement, and nothing it says should be read as authorising you to skip a lock-out step, a discharge procedure, or any other safety measure. Where the assistant and the manufacturer disagree, the manufacturer is right.

The assistant does not provide legal, safety-certification, or warranty advice, and its answers are not a substitute for the manufacturer's own technical support.

The assistant runs on Google's Gemini API, so using it means your questions are sent to Google. We ask you to agree to that before the assistant will answer a question you type, and you can decline or withdraw at any time from your account menu. If you do, the assistant will not answer and the rest of TFA carries on working. What Google does and does not do with that content is set out in our privacy policy.

If the assistant ever produces something offensive, inappropriate, or unsafe, report it from the response itself — the thumbs-down control has an option for exactly this, and you can add a comment. Reports reach us directly, we review them, and we use them to correct and constrain what the assistant produces. Please do report rather than work around it; a bad answer nobody flags is one the next technician gets too.

You keep whatever rights already exist in what you put into TFA — the notes you write, the questions you ask, the documents you upload. As between you and your employer, the service records and documents in TFA belong to your employer, and Nexera handles them on their instruction.

By uploading something you confirm you are allowed to. Do not add a manual, bulletin, or drawing that your organization is not licensed to hold and share internally.

A document you upload is visible to everyone at your dealer, not just to you, and it can be searched by any TFA user there. No other dealer can see it. Administrators and service managers at your dealer can withdraw a document from search and delete it.

Nexera needs permission to operate the service on this content: to store it, index it, display it back to authorised users at your dealer, and send the parts needed to answer a question to the AI provider described in the privacy policy. That permission exists for running and improving TFA and for nothing else. We do not sell it and we do not use it for advertising.

If you send us feedback or a suggestion, we may act on it without owing you anything for it. That is not a claim on your work — only on the idea you volunteered.

TFA is in active development. Features change, appear, and are withdrawn, sometimes at short notice, and the app updates itself as we deploy. We may take the service down for maintenance.

TFA needs a working network connection. It is not designed to work offline, and it depends on services we do not control, including the app stores and the AI provider. We do not promise it will be available when you need it, and any uptime commitment your employer has is in their agreement, not here.

TFA may send you notifications. They are a convenience and not a guarantee: they are delivered by Apple's and Google's push services, which we do not operate, and they can be delayed, duplicated, or dropped entirely. Never treat a notification, or the absence of one, as a reliable record of work assigned to you — the app itself is the record. You can turn them off at any time, either in your device settings or with the push notifications switch in your account menu, and the rest of TFA keeps working.

Your employer can close your account whenever it decides to — when you change role, or leave, or for its own reasons. Access stops immediately when it does.

Nexera may suspend or withdraw your access without notice if an account is being used in a way that breaks these terms, threatens the security of the service, or puts other users' data at risk. Where it is sensible to do so we will raise it with your employer first.

You can stop using TFA at any time by signing out and uninstalling the app. What happens to your dealer's data afterwards is governed by their agreement with Nexera, not by this page — that data is your employer's, and its fate is not ours to decide on their behalf.

TFA, including the app, the service behind it, and the Nexera name and marks, belongs to Aspire USA LLC and its licensors. You get a personal, non-transferable, non-exclusive right to use the app while your account is open and for your employer's service work. It is licensed to you, not sold, and nothing here transfers ownership of any part of it.

Manufacturer names, model numbers, and error codes appear in TFA to identify equipment. Those marks belong to their owners, and their appearance does not imply any endorsement of or affiliation with TFA.

To the fullest extent the law allows, TFA is provided as is and as available, without warranties of any kind, whether express or implied, including any implied warranty of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the service will be uninterrupted or error-free, or that anything the assistant produces is accurate, complete, or suitable for a given machine.

To the fullest extent the law allows, Aspire USA LLC is not liable to you for indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost data, or business interruption, arising out of your use of TFA. Where liability cannot be excluded, our total liability to you personally is limited to one hundred US dollars (US$100).

That limit reflects what this document is. Commercial remedies belong to your employer's agreement with Nexera, which is where the money and the service commitments sit. This page is not the place those are resolved, and it does not limit whatever rights your employer negotiated.

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages. Where that is so, the exclusions and limits above apply only as far as that jurisdiction permits, and nothing here removes a right you have that cannot be waived.

This agreement is between you and Aspire USA LLC only. It is not with Apple, Google, or any other app store, and none of them is responsible for TFA or its content.

Nexera alone is responsible for supporting TFA and for any warranty claim about it. Apple and Google have no obligation to provide maintenance or support. If TFA fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price if there was one; beyond that, Apple has no other warranty obligation in relation to TFA. TFA is currently distributed at no charge.

Nexera, not the app store, is responsible for addressing any claim that TFA or your use of it infringes another party's intellectual property, fails to comply with law, or gives rise to a product liability or consumer protection claim.

You confirm you are not located in a country subject to a US Government embargo or designated as supporting terrorism, 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 may enforce them against you directly. Your use of TFA is also subject to the app store's own terms.

We will change these terms as TFA develops, and the effective date at the top of this page always reflects the current version. Continuing to use TFA after a change means you accept the revised terms.

If a change materially affects your rights, we will tell your organization rather than rely on you noticing a new date here — the same approach the privacy policy takes.

This is an interim document, published while the agreements between Nexera and its dealer customers are being revised. Expect it to be replaced rather than amended.

These terms are governed by the laws of the State in which Aspire USA LLC is organized and by the laws of the United States, without regard to their conflict-of-laws rules.

If any part of these terms is found unenforceable, the rest continues to apply. Disputes between Nexera and your employer are handled under their own agreement, which may specify a different forum; nothing here displaces it.
