# Terms of Service

*Effective November 6, 2026*

These Terms govern your access to and use of the Hyperouter website at hyperouter.app, the Hyperouter API, Hyperouter Chat, Hyperouter Studio and related services (together, the “Service”). The Service is provided by Hybermedia Co., Limited, a company incorporated in Hong Kong, of Room A08, 2/F, Lee Ka Industrial Building, 8 Ng Fong Street, San Po Kong, Kowloon, Hong Kong, under the name Hyperouter (“Hyperouter”, “we”, “us”). Please read them carefully.

## 1. Agreement {#t1}

By creating an account, requesting or using an API key, or otherwise using the Service, you agree to these Terms and to our [Privacy Policy](privacy.md). If you use the Service on behalf of an organization, you confirm you are authorized to bind that organization, and “you” refers to it. You must be at least 18 years old, or the age of majority where you live, to use the Service.

## 2. Accounts and API keys {#t2}

- You must give accurate account information and keep it up to date.
- API keys are credentials. Keep them confidential and do not embed them in client-side code. You are responsible for all usage and charges made with your keys, including unauthorized usage, until you ask us to revoke them.
- Notify us promptly at [account@hyperouter.app](mailto:account@hyperouter.app) if you believe a key has been exposed.

## 3. The Service {#t3}

Hyperouter provides a single interface for sending requests to large language models operated by third parties (“Model Providers”). When you send a request, we route it to a Model Provider according to our routing logic and any preferences you set, and return the provider’s response to you.

We do not create, train or control the models, and we do not review outputs before they are returned. Model availability, capabilities and prices are set by Model Providers and can change at any time. We may add or remove models and venues without notice.

## 4. Credits, fees and payment {#t4}

- **Prepaid credits.** Usage is paid from a prepaid balance of credits denominated in US dollars. Requests are charged at the Model Provider’s list price for the tokens processed, as shown by our Models API at the time of the request.
- **Purchases.** Credits are bought in US dollars, from US$5 to US$10,000 per purchase. Where card payment is offered, cards are processed by our payment processor, Stripe; we do not see or store your full card details. You can also pay by the other methods shown in the dashboard, credited by our staff after you open a top-up ticket and the payment is confirmed. The amount, the fee and the credits you will receive are shown before you pay.
- **Prices on our website.** Prices shown on our website, in our documentation and in examples may be updated later than the prices we charge. The price that applies to a request is the one our Models API shows at the time of the request.
- **Top-up fees.** A fee of 5.5% of the amount paid, with a minimum of US$0.80, is deducted from each purchase when it is credited to your balance, whatever the payment method. It is shown on the Credits page of the dashboard before you pay. We may change fees for future purchases.
- **Failed requests.** Requests that fail on every venue are not charged. For streamed responses that stop partway, including when you disconnect, you are charged for the tokens the Model Provider produced up to that point.
- **Rebates.** Where a written agreement with us gives you a rebate, it is credited to your balance as rebate credit after the month's statement is posted. Rebate credit can be used only to pay for usage of the Service. It is never refunded as cash, on request or on closure, and has no cash value.
- **Refunds.** You may ask for a refund of a purchase within 24 hours of the time it was processed, by email to [account@hyperouter.app](mailto:account@hyperouter.app) or a ticket in the dashboard. We refund the credits from that purchase that are still unused, to the payment method you paid with, usually within 5 to 10 business days; the top-up fee is not refunded. After 24 hours, purchased credits are non-refundable, except where the law requires a refund. Rebate credit is not refundable.
- **Expiry.** Credits do not expire while your account is in good standing. Credits are non-transferable, except that a reseller may move credit to and from the sub-accounts it funds, and have no cash value outside the Service.
- **Taxes.** Prices exclude taxes. You are responsible for any taxes that apply to your purchases, other than taxes on our income.
- **Disputes and chargebacks.** If you think a charge is wrong, contact us first at [account@hyperouter.app](mailto:account@hyperouter.app); we answer within 2 business days. If a payment is reversed or disputed with your bank, we may suspend the account until the matter is settled, and credits from that payment are removed from your balance.

## 5. Acceptable use {#t5}

You agree not to use the Service to:

- break any law, or infringe or misappropriate anyone’s rights;
- generate or distribute child sexual abuse material, or content that sexualizes minors;
- develop weapons capable of mass casualties, or plan or promote violence;
- create malware, attack systems, or gain unauthorized access to data or networks;
- defraud, impersonate or deceive people, including undisclosed automated messaging at scale;
- violate the usage policies of the Model Provider serving your request;
- resell raw API access or share keys outside your organization without our written consent;
- probe, overload or interfere with the Service, or work around rate limits or billing.

Model Providers may apply their own content filters. A request refused by a provider is not a breach of these Terms by us.

## 6. Your content {#t6}

You keep all rights to the prompts, files and other inputs you send (“Inputs”) and, as between you and us, to the outputs you receive (“Outputs”). You grant us a limited license to process Inputs and Outputs only as needed to provide, secure and bill for the Service, including passing them to the Model Provider that serves your request.

We keep Inputs and Outputs encrypted for 180 days to meet our legal obligations, and disclose them only to authorities that present a valid legal request. We do not use your content to train models. See the [Privacy Policy](privacy.md) for details. You are responsible for your Inputs and for how you use Outputs, and for checking Outputs for accuracy before relying on them.

## 7. Model Providers {#t7}

Each Model Provider processes your request under its own terms and data policies. By routing to a provider, you agree to comply with that provider’s usage policies. You can restrict which providers receive your requests using routing settings. We are not responsible for the acts or omissions of Model Providers.

## 8. Beta features {#t8}

Features labeled beta, preview or early access, including Hyperouter Chat and the API during private beta, are provided for evaluation. They may change or be discontinued, may be less reliable, and are excluded from any uptime commitment.

## 9. Suspension and termination {#t9}

You may stop using the Service at any time and close your account from the dashboard; closure takes effect at once and cannot be undone. A staff account must lose its staff roles before it can be closed. We may suspend or terminate access if you breach these Terms, if your use creates security or legal risk, or if required by law. Where reasonable we will give notice first. On closure, the remaining balance is not refunded; to get back a recent purchase, ask for its refund within 24 hours of it (Section 4) before you close the account. Rebate credit is not refunded, and a sub-account's remaining credit returns to the reseller that funded it.

## 10. Disclaimers {#t10}

THE SERVICE AND ALL OUTPUTS ARE PROVIDED “AS IS” AND “AS AVAILABLE”. TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTY THAT OUTPUTS ARE ACCURATE, COMPLETE OR SAFE. AI outputs can be wrong. Do not rely on them as professional, legal, medical or financial advice.

## 11. Limitation of liability {#t11}

TO THE FULLEST EXTENT PERMITTED BY LAW, HYPEROUTER WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA OR GOODWILL. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM AND (B) US$100. These limits do not apply where they are prohibited by law.

## 12. Indemnity {#t12}

You will defend and indemnify Hyperouter against third-party claims, and related losses and costs, arising from your Inputs, your use of Outputs, or your breach of these Terms.

## 13. Changes to these Terms {#t13}

We may update these Terms. For material changes we will give at least 14 days’ notice by email or on this page before they take effect. Continuing to use the Service after that means you accept the updated Terms. For accounts opened before November 6, 2026, the changes to Sections 4 and 9 on refunds at account closure take effect on November 20, 2026.

## 14. General {#t14}

These Terms are the entire agreement between you and us about the Service and replace any earlier understanding. If any part is unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition or sale of assets. These Terms are governed by the laws of the Hong Kong Special Administrative Region, without regard to conflict-of-law rules, and disputes will be resolved in the courts of Hong Kong unless applicable law requires otherwise.
