Terms of Service

Effective September 14, 2026. Tomasetti Tech LLC, Longmont, Colorado, United States.

These terms cover your use of AudiophileGPT. They are written in plain language because you should be able to read them once and know what you agreed to. Two sections matter more than the rest: section 8, because this software will tell you to open equipment that can kill you, and section 14, because it limits what you can recover from us. If anything here is unclear, email support@audiophilegpt.com and we will explain it.

1. Agreement

By using AudiophileGPT you agree to these terms. If you do not agree, do not use the service. These terms are between you and Tomasetti Tech LLC, a Colorado limited liability company. If you are using the service for a business, you are confirming you have the authority to accept these terms for that business.

2. The service, and what each tier gets

AudiophileGPT answers questions about vintage and modern hi-fi equipment. You ask, it retrieves matching passages from a repair knowledge base, and a language model writes an answer. What you get depends on which tier you are in:

Tier	What it includes	What it costs
Anonymous trial	3 questions in any rolling 5 hours, counted against your browser and your network address	Free, no account
Free account	10 questions in any rolling 24 hours, across every device you sign in from	Free, one email address
Pro	150 questions in any rolling 24 hours, across every device you sign in from, and 5 a day on the strongest model	$9.00 USD per month or $90.00 per year, plus tax
Studio	300 questions in any rolling 24 hours, across every device you sign in from, and 20 a day on the strongest model	$19.00 USD per month or $190.00 per year, plus tax

The counter rolls rather than resets. Each question drops off the count that many hours after you asked it, one at a time.

Paying

Pro is $9.00 USD a month or $90.00 a year; Studio is $19.00 a month or $190.00 a year, billed in advance, plus tax. Sales tax is added at checkout where we are required to collect it, and the total is shown to you before your card is charged. The card is handled by Stripe. We never see or store your card number.
The subscription renews automatically each period, on the date of your first payment, at the same price plus tax, until you cancel it. This is the auto-renewal disclosure and it is the plain version of it: no action from you means another month or year is charged, at the same price and whatever tax applies to your address at that time.
You can cancel at any time and you keep access until the end of the period you already paid for. The refunds and cancellation page has the details, including the 14-day refund.
Prices can change. If the price of the paid tier goes up, we will email you at least 30 days before it applies to you, and you can cancel before it does.
If a payment fails, Stripe retries it over the following days. If it keeps failing the subscription is cancelled and the account drops back to the free account tier, which is 10 questions in any 24 hours. Nobody is chased over $9.
Taxes are added to your plan's price, not included in it. Where we are required to collect sales tax, Stripe works it out from the address on your card, adds it, and shows you the total before the charge. Where no tax applies to you, you pay $9.00. If your state or city changes its rate, the total you are charged changes with it, and that is not a price change: section 8 of the refunds and cancellation page explains what does and does not count as one.

Fair use limits

Beyond the tier counters, a single connection is limited to about 10 requests a minute. That number is invisible to a person asking questions in a sitting and it turns an automated loop into errors. Anonymous questions are also capped at 6 in any rolling 5 hours for a single network address, so one address cannot spend the free tier for everyone behind it. If you hit that ceiling you may be refused even though your own three questions are not used up, and the error message will say so. A free account is not capped this way: it counts against the account rather than the address, so it keeps working from a shared connection whose address is spent. That is the usual reason to make one.

3. Eligibility

You need to be at least 13 years old to use AudiophileGPT, and at least 18 to pay for it. If you are between 13 and 18, use it only with a parent or guardian's permission. Do not use the service if the law where you live does not let you accept these terms.

4. Your account

One account per person. Do not make several accounts to get around the free tier's 10 questions. That is the thing the limit exists to prevent, and it is the reason the paid tier is $9 and not more.
Use an email address you actually control. It is how you would recover the account and how we reach you about billing.
Keep your password to yourself. You are responsible for what happens under your account. Tell us at support@audiophilegpt.com if you think someone else has it.
Do not share a paid account outside your household. The paid tier is one person's use. Sharing it with a forum breaks the arithmetic that makes it $9.

5. Acceptable use

Do not use AudiophileGPT to do any of these things:

Anything illegal, or anything that would help somebody do something illegal.
Asking questions that are not about audio or electronics, at volume. The service runs a topic filter and it will refuse you, and a habit of pushing against it is a reason to close an account.
Scraping, bulk querying, or reselling access. The API is not a product you can white-label, and the counters and rate limits are not a suggestion.
Trying to get the model to produce content that has nothing to do with audio repair, or to reveal the knowledge base or the system prompt as a bulk dump.
Attacking the service: probing it, flooding it, trying to break the metering, or trying to reach another user's account.
Anything that breaks the law on export control or sanctions, or that puts us in a position where we would have to break one.

We can suspend or close an account that does these things. If a paid account is closed for abuse, the current month is not refunded.

6. Your questions

Your questions stay yours. You are not transferring ownership of anything by typing into the box. You give us permission to do the things we have to do to answer you: send the question, and the knowledge base passages matched to it, to the model provider so it can generate an answer, and keep the counter. That permission is only for running the service, and it ends when you stop using it, apart from anything we are required to keep for tax or accounting reasons.

Your conversations are stored in your own browser, not on our server. See the Privacy Policy for exactly what is and is not kept, including the 120-character excerpts that reach the server log when a question is refused or the model fails.

7. The answers

You can use the answers for anything you like, including commercially. Repair a customer's receiver with one. Put the good ones in your own notes.
You may not claim copyright in generated text, and neither can we. In the United States, material generated entirely by a machine without human authorship is generally not copyrightable. That cuts both ways: nothing stops the next person from getting a similar answer.
The answer may resemble training data. Language models learn from text written by other people, and a generated answer can reproduce a phrase, a passage, or a conclusion that came from somewhere else. If an answer reads like it was copied out of a service manual, treat it that way and check the manual.
Do not present the answers as ours. Do not say Tomasetti Tech LLC reviewed or endorsed a repair because AudiophileGPT wrote something.

8. What the answers are, and what they are not

Voltage, and the limits of an AI answer

The answers are written by a language model from a knowledge base and from patterns in its training data. They are probabilistic. They can be wrong, they can be right for the wrong reason, and they can be confidently wrong in a way that reads exactly like the correct answer. There is no technician reading it before you do.

Tube amplifiers and power supplies hold voltages that will kill you, and they hold them after the unit is unplugged. A generated answer does not know that you cannot identify which capacitor is charged, or that you were going to reach in with one hand while leaning on the chassis. If you do not already know how to work safely inside equipment that stores a lethal charge, do not start because a model told you the next step. Find a qualified technician.

This is not a licensed engineering service, it is not a substitute for a technician who can put a meter on your actual unit, and it is not advice about fire, medical devices, or anything else where being wrong has consequences beyond a smoked resistor. On mains wiring the box answers with the safety limits stated: power off at the breaker, anything charged gets discharged before hands go in, and in-chassis mains wiring belongs to a licensed electrician. You are responsible for verifying anything before you act on it.

To say it once more, plainly: check the answer. Look it up in the service manual. Ask someone who has done the repair. The service is good at pointing you in the right direction and it is not a guarantee of anything.

9. Third-party services

AudiophileGPT is a thin layer on top of a model provider and a payment processor, and their terms apply to their part in addition to ours.

DeepSeek writes every answer, including the free ones, and processes the question in the People's Republic of China. Read section 4 of the Privacy Policy before you type anything you would not want stored there. Their terms govern their side of it.
Stripe takes payments and manages the subscription. Their terms and their privacy policy apply to the payment.
If a model provider changes its terms, its prices, or its availability, what this service can do changes with it, sometimes quickly.

10. The free tiers, and uptime

The anonymous trial and the free account are free and are offered as best effort. There is no uptime promise on any tier, and no service level agreement on any tier. The service can be slow, it can be down for maintenance, it can refuse a question, and the model behind it can be unavailable for reasons that have nothing to do with us. If the upstream model fails, the question is refunded to your counter, so a failure never costs you a question.

We can change the free tiers: the number of free questions, the length of the window, or whether the free tier exists at all. We will give notice on the page before a change like that. We will not change what a paid subscription includes in the middle of a period you have already paid for.

11. Intellectual property

The site, the code that runs it, the repair knowledge base, the layout, and the AudiophileGPT name belong to Tomasetti Tech LLC. Nothing in these terms gives you a licence to any of it beyond looking at the pages and using the service the way it is meant to be used. Do not copy the knowledge base out, do not clone the interface, and do not use the name to describe your own thing.

Text on the page that we wrote is ours. Your questions are yours. The generated answers are in between, as section 7 explains.

12. Termination

You can stop at any time. Cancel the subscription, sign out, and clear your browser data. Nothing else is needed.
We can close an account for breaking these terms, especially section 5. If we do it, we will tell you why. For a paid account closed for abuse, the current month is not refunded.
We can end the service. If AudiophileGPT shuts down, paid subscribers get notice by email and a refund of the unused part of the month they are in.

13. No warranty

THE SERVICE IS PROVIDED AS IS AND AS AVAILABLE, WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT THE LAW ALLOWS, TOMASETTI TECH LLC DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR FREE, THAT THE ANSWERS WILL BE ACCURATE OR USEFUL, OR THAT ANY DEFECT WILL BE CORRECTED. NO ADVICE OR INFORMATION OBTAINED FROM THE SERVICE CREATES A WARRANTY THAT IS NOT IN THESE TERMS.

14. Limitation of liability

TO THE FULLEST EXTENT THE LAW ALLOWS, TOMASETTI TECH LLC IS NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST DATA, OR DAMAGE TO EQUIPMENT, WHETHER THE CLAIM IS IN CONTRACT, TORT, OR ANYTHING ELSE, AND EVEN IF WE WERE TOLD SUCH DAMAGE WAS POSSIBLE.

Our total liability for any claim about the service is capped at the greater of $9.00 or the amount you paid us in the 12 months before the claim arose.

Some places do not allow a disclaimer of certain warranties or a limitation like the one above, so parts of sections 13 and 14 may not apply to you, and you may have rights that these terms cannot take away. Nothing in these terms limits liability for fraud, for wilful misconduct, for death or personal injury caused by negligence, or for anything else that cannot be limited by law.

15. Indemnity

If somebody brings a claim against us because of something you did with the service, you agree to cover the reasonable cost of dealing with it. That means using the service to break the law, breaking section 5, republishing an answer as if it were professionally reviewed advice, or using an answer in a way that damages somebody. This works the other way too: we are responsible for our own conduct, not for yours.

16. Governing law and venue

These terms are governed by the laws of the State of Colorado, United States, without regard to its conflict of law rules. Any dispute that cannot be settled by talking to us goes to the state or federal courts sitting in Boulder County, Colorado, and you and we both agree to those courts.

If you are a consumer living somewhere else, this does not take away the protection of the mandatory consumer law in the place where you live, and you may be able to bring a claim in your own courts where that law gives you the right to.

17. Changes to these terms

If these terms change, the effective date at the top changes with it. The version that applies to you is the one that was posted when you used the service. Your continued use after a change is posted counts as accepting the change. If a change materially reduces what a paid subscription includes, we will email you before it takes effect and you can cancel.

18. Contact, and copyright complaints

Anything about these terms, an account, or a charge: support@audiophilegpt.com. A person reads it, and we answer within 5 business days.

Copyright complaints. If you believe an answer reproduced something you own, or that a page here uses your material without permission, email dmca@audiophilegpt.com with the subject line "Copyright complaint" and include: what you own, where the material appears, why you believe it infringes, your contact details, a statement that you have a good faith belief the use is not authorised, and a statement under penalty of perjury that the information is accurate and that you are the owner or authorised to act for them.

Be aware that what we can act on is narrower than the takedown procedure you may be expecting, and the reason is structural rather than a choice. Nothing on this service is posted by other people. There is no forum, no comments, and no upload, so there is no material of yours sitting on our machine for a notice to remove, and no third party for us to pass a notice on to. Answers are generated when somebody asks and written into that person's own browser, which means the copy in front of them is not one we can reach or delete. What we do control is the repair knowledge base the answers are drawn from and the instructions the model writes under, and if a passage in either one is causing your material to come back out, telling us which passage is what gets it changed. Section 7 already tells every visitor to treat an answer that reads like a manual as copied from one, in the bullet about answers that resemble training data.
