Terms of Service

These terms govern your use of AIITO ("the Service"), provided by KATO INFORMATION TECHNOLOGY CO., LTD. (Business Registration Number 60707143, "we", "us").

1. Application

These terms set out the conditions on which we provide the Service and the rights and obligations between you and us. They apply to everything relating to your use of the Service.

2. Definitions

  1. You — the person or legal entity that enters into the contract for the Service.
  2. Authorised User — an individual whom you authorise to use the Service on your behalf.
  3. Content — text, images, email, websites and the like that you create, store or send.
  4. AI output — text, images and the like generated by the AI features of the Service.
  5. External AI service — the third-party generative AI technology the Service uses.

3. Registration and account

  1. You apply to register in the manner we specify. The contract is formed when we accept your application. We may decline an application.
  2. If you are an individual, you must be at least 18 years old and have legal capacity to enter into this contract. Persons under 18 may not subscribe to the Service.
  3. You must not share individual login credentials. You are responsible for ensuring that your Authorised Users keep their credentials secure, and for looking after your own ID, password and two-factor authentication. You bear responsibility for loss arising from inadequate management or use by others. Tell us immediately if you become aware of unauthorised use.

4. What we provide, and changes

The Service provides AI-assisted website creation, AI-assisted email drafting and management, hosting for websites and email, and related operational support.

We may change what the Service provides where the change is in the general interest of users, or where it is consistent with the purpose of the Service and the change is necessary and reasonable.

Where a change materially reduces what you receive, we will tell you by email to your registered address at least 30 days beforehand, and you may cancel before it takes effect without penalty. If you do, we refund the unused portion of any fees you have paid in advance.

5. Fees, payment and non-payment

  1. You pay our published fees by credit card (processed by Stripe). Fees are quoted in Hong Kong dollars. No sales tax, VAT or goods and services tax is added. Fees and billing dates are as published by us.
  2. Fees are paid monthly in advance and renew automatically until you cancel. Times and dates are Hong Kong time.
  3. Where you subscribe on the 29th, 30th or 31st, we bill on the last day of any month that has no such date.
  4. To avoid the next charge, cancel before your renewal date. If you cancel on the renewal date itself, the charge may already have been taken.
  5. If a payment fails, we suspend the Service after a grace period of three days. Your service content is then kept for 30 days from suspension, and paying within that time restores the account. After 30 days, the account and its service content are deleted. Billing, transaction, security and legal records may be retained for longer as described in section 16 and the Privacy Policy.

6. What you must not do

  1. Anything unlawful or contrary to public order and morals.
  2. Infringing the rights of us or others, including intellectual property and privacy.
  3. Sending spam, indiscriminate or bulk email, or mail you have no permission to send.
  4. Sending or publishing malware, or content that facilitates unauthorised access.
  5. Placing an unreasonable load on the Service or its infrastructure, or interfering with its operation.
  6. Attempting to access another user's data or account.
  7. Reselling or sublicensing the Service without our consent.
  8. Impersonating another person or misrepresenting your affiliation.
  9. Anything else we reasonably determine to be inappropriate.

7. Action on misuse

  1. Where we reasonably believe that you have breached section 6, including following our review of an abuse report, we may take proportionate action such as suspending the Service, removing affected content or terminating the contract.
  2. Where the matter is urgent — ongoing attack, large-scale spam, or a risk to other users — we may act first and notify you afterwards.
  3. We may disclose information to the extent required by law or by a lawful request from an authority.

8. Content and AI output

  1. Rights in your Content remain yours. You grant us the scope of use necessary to operate the Service (storage, transmission, backup, fault investigation).
  2. We do not claim rights in AI output. AI output is not guaranteed to be accurate, complete, current or original. It may resemble the work of others, and similar output may be generated for other users. It is not legal, medical, tax or other professional advice.
  3. You are responsible for checking AI output before you send, publish or rely on it. Please treat it as a draft prepared for you to review, not as finished work.
  4. To provide the AI features we send your input to an external AI service. Under the commercial API we use, input and output are not used to train AI models.
  5. You are responsible for ensuring that your Content does not infringe the rights of others.
  6. What you enter into the AI features will often contain personal data about other people — your own clients, correspondents and staff. You confirm that you are entitled to submit it, that you have given any notice and obtained any consent required to do so, and that you will not submit personal data that is excessive or unnecessary for what you are asking the AI to do.

9. Email

  1. You must not use the Service to send spam or to send mail in bulk without permission.
  2. We may set sending limits to protect deliverability for all users.
  3. We do not guarantee delivery of email. Delivery depends on the receiving provider, and mail may be treated as spam or rejected for reasons outside our control. This does not affect our duty to use reasonable care and skill in operating the mail service.

10. Domains and DNS

  1. Where you register or renew a domain through us, the terms of the registry and registrar also apply.
  2. You are responsible for the accuracy of the registrant details you provide.
  3. Where you manage DNS yourself, we are not responsible for outages caused by your settings.

11. Resources and limits

Storage, transfer and other allowances are as specified for each plan. Where usage substantially exceeds the allowance, or affects other users, we may ask you to move to a higher plan, or may restrict the Service.

12. Backups

  1. We take backups for the purpose of operating the Service. These are for our operational purposes and are not a substitute for your own backups.
  2. We do not guarantee that data can be restored from a backup. Please keep your own copies of anything important.
  3. Nothing in this section affects our duty to use reasonable care and skill in taking and keeping backups.

13. Availability, interruption and termination of the Service

  1. We do not offer a service level agreement and we do not guarantee a particular level of availability. This does not affect our duty to use reasonable care and skill in providing the Service.
  2. We may interrupt the Service without prior notice where necessary for urgent maintenance, or because of failure of equipment, a natural disaster, or an act of a third party.
  3. We will give advance notice of planned maintenance in the manner we specify.
  4. We may terminate all or part of the Service, giving at least 30 days notice by email to your registered address. If we do so for reasons other than your breach of these terms, we refund the unused portion of any fees you have paid in advance.

14. Support

Support covers the operation of the Service. It does not extend to programming for you, to the content of your business, or to products of others that we do not provide.

15. Limitation of liability

  1. Except where our wilful misconduct or gross negligence is involved, our total liability in respect of the Service is limited to the fees you paid us in the 12 months before the event giving rise to the claim.
  2. We are not liable for indirect, incidental, special or consequential loss, or for lost profits.
  3. Nothing in these terms excludes or limits our liability:
    1. for death or personal injury caused by negligence;
    2. for fraud or fraudulent misrepresentation;
    3. arising from any term implied by the Supply of Services (Implied Terms) Ordinance (Cap. 457), to the extent that such liability cannot lawfully be excluded or restricted;
    4. for wilful misconduct; or
    5. which cannot otherwise lawfully be excluded or limited.

16. Termination and your data

  1. You may cancel at any time from the customer portal. Cancellation and refunds are governed by the Refund and Cancellation Policy.
  2. Your account is suspended at the end of the period you have paid for. We keep your service content and operational account data for 30 days from suspension, and then delete it. We may retain billing, transaction, security and legal records for longer where reasonably necessary or required by law. The same 30-day rule applies after a failed payment.

17. Notices

We give notice by email to the address you registered, or by publishing on the Service.

Where a notice affects your rights, your charges, or the continuation of the Service — including changes under sections 4 and 19, and termination under section 13 — we send it by email to your registered address.

Notice by email is treated as given when sent to your registered address and not returned to us as undeliverable; notice by publication, when published. Please keep your registered email address up to date.

18. Assignment

You may not assign your rights or obligations under these terms without our consent.

You agree that we may transfer the Service, together with this contract and your personal data, as part of a transfer of all or part of our business, provided that the transferee agrees to be bound by these terms. We will tell you by email at least 30 days before the transfer takes effect, and you may cancel before it takes effect without penalty, in which case we refund the unused portion of any fees you have paid in advance.

19. Changes to these terms

We may change these terms where the change is in the general interest of users, or where it is consistent with the purpose of the contract and the change is necessary and reasonable. We will publish the revised terms and the date they take effect on the Service in advance.

Where a change is materially to your disadvantage, we will also tell you by email to your registered address at least 30 days beforehand, and you may cancel before it takes effect without penalty.

20. Governing law and jurisdiction

These terms are governed by the laws of the Hong Kong Special Administrative Region. The courts of Hong Kong have exclusive jurisdiction over any dispute relating to the Service, except where applicable law permits or requires proceedings to be brought elsewhere.

21. Language

These Terms are published in English, Traditional Chinese and Japanese. If there is any inconsistency between the versions, the English version prevails, except to the extent that applicable law requires otherwise.
