Terms of Service

The agreement between you and CoAI Host for our cloud VPS services.

Last updated: 26 September 2026

1. About these Terms

These Terms of Service ("Terms") govern your use of the virtual private server (VPS) and related services (the "Services") provided by CoAI Host ("CoAI Host", "we", "us" or "our") through host.coaiwork.com. By creating an account, placing an order or using the Services, you agree to these Terms.

Our Acceptable Use Policy ("AUP") forms part of these Terms, and our Privacy Policy describes how we handle personal data. If you do not agree to these Terms and the AUP, do not order or use the Services.

2. Your account

3. The Services

Each plan is a KVM virtual server with the vCPU, memory, NVMe SSD storage, network rate limit and monthly traffic allowance described on the order page at the time you order. Unless stated otherwise:

We may change or improve the underlying hardware, software and network, provided the resources of your plan are not reduced during a paid billing period.

Windows Server (bring your own licence)

On the CoAI S4 and CoAI S8 plans you may choose Windows Server 2025, installed as Microsoft's 180-day evaluation edition. We do not sell, include or sublicense any Microsoft licence; Windows Server is offered on a bring-your-own-licence basis only.

4. Orders, billing and payment

5. Non-payment, suspension and termination

Renewals are handled automatically as follows (all dates in Japan Standard Time, JST):

WhenWhat happens
7 days before the due dateThe renewal invoice is issued.
3 days before the due dateA payment reminder is sent.
Due dateA saved card, if any, is charged automatically.
1 day after the due dateFirst overdue notice.
3 days after the due dateIf the invoice is still unpaid, the service is suspended: the server is shut down and cannot be accessed. Your data is kept.
4 days after the due dateSecond overdue notice.
10 days after the due dateThird overdue notice: final warning that the server and all of its data will be permanently deleted on the termination date.
Payment while suspendedThe service is unsuspended automatically once the overdue invoice is paid in full, and the server is started again.
14 days after the due dateIf the invoice is still unpaid, the service is terminated: the server and all of its data are permanently deleted and its IP address is released. Terminated services and data cannot be recovered. The unpaid invoice is cancelled at the same time.

Suspended services are shut down and inaccessible: while a service is suspended, for whatever reason, its server is powered off, the console and the power controls in the client area are disabled, and the server is not started again until the service is unsuspended. The data on the server is kept while the service is suspended.

We may also suspend or terminate a Service immediately, with or without notice, if you breach these Terms or the AUP, if we reasonably suspect fraud or a chargeback is filed, if your Service threatens the security or stability of our network or other customers, or if we are required to do so by law. Where the breach can be fixed, we will usually give you an opportunity to fix it first.

6. Cancellation

7. Refunds

Payments are non-refundable except where required by law. We do not give pro-rata refunds for unused time. Any refund, credit or partial refund is at CoAI Host's sole discretion. No refunds are given for Services suspended or terminated because of a breach of these Terms or the AUP.

8. Your responsibilities

9. Availability and support

We aim to keep the Services available at all times but do not guarantee uninterrupted or error-free operation. Unless a separate written service level agreement applies, no uptime guarantee or service credit is provided. We may carry out planned maintenance and will try to give advance notice of work that is expected to cause downtime. Emergency maintenance may be carried out without notice.

Support is provided by email and through support tickets in the client area. Support covers the availability of your server, network and control panel; it does not include administering software inside your server.

10. Your data and privacy

You keep ownership of the data you store on your server. We do not access the contents of your server except where needed to investigate abuse or a security incident, to protect our network, to provide support you have asked for, or to comply with the law. We use your account information to provide and bill the Services and to contact you about them, and we may disclose information where required by law or valid legal process. Our Privacy Policy explains in detail what we collect, why, who processes it for us and how long we keep it.

11. Service provided "as is"

The Services are provided on an "as is" and "as available" basis. To the maximum extent permitted by law, we disclaim all warranties, whether express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement.

12. Limitation of liability

To the maximum extent permitted by law, CoAI Host will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, revenue, business, goodwill or data, arising from or related to the Services. Our total liability for any claim relating to the Services is limited to the amount you paid for the affected Service during the billing period in which the claim arose.

13. Indemnity

You agree to indemnify and hold CoAI Host harmless from any claims, losses and expenses (including reasonable legal fees) arising from your use of the Services, the content on your server, or your breach of these Terms or the AUP.

14. Changes to these Terms

We may update these Terms or the AUP from time to time. The current version is always published on this page with its "Last updated" date. We will notify you by email of material changes before they take effect. Continuing to use the Services after a change takes effect means you accept the updated Terms.

15. Contact

Questions about these Terms, billing or your account can be sent to support@coaiwork.com or submitted as a support ticket in the client area.
