1. Terms Overview

These Terms of Service (“Terms”) govern the relationship between you (“User” or “you”) and Sun Network Company Limited (JUSTG). They apply to all services provided by JUSTG, including cloud VPS in Tokyo, Seoul and Moscow, dedicated servers in Tokyo, Seoul, Moscow and Johannesburg, colocation, IP transit and IPv4 leasing (together, the “Services”). By registering an account or by ordering, using or paying for any of the Services, you agree to these Terms and to the policies referenced in them, which supplement any individual service agreement you may have with us.

You confirm that you are at least 18 years old or, if you are acting on behalf of a company or other organization, that the organization is duly formed and in good standing and that you have full authority to accept these Terms on its behalf.

You agree to provide accurate, complete and up-to-date information when you register and when you renew any Service, and to update it promptly if it changes.

We may revise these Terms at any time without prior notice. The current version is always published on this page, and the “Last updated” date above will be revised. Your continued use of the Services after a change means that you accept the revised Terms.

2. Term, Payment & Account Renewal

• Term of service: the term of each Service begins when you accept these Terms and order the Service, and ends as described in your order or service agreement.
• Payment: you agree to pay all fees for purchasing and renewing the Services.
• Renewal: please renew at least 2 days before the due date. If a renewal invoice is not paid by its due date, the Service is suspended automatically. If the invoice is still unpaid 7 days after the due date, the Service is cancelled automatically and the data stored on it is deleted and cannot be recovered. JUSTG is not responsible for any loss caused by late or missed payment.
• Authority: if you register on behalf of a company or group, you must be authorized to bind it to every provision of these Terms.

3. Refund Policy

All JUSTG services, including cloud servers, dedicated servers, colocation, IP transit and IP leasing, are non-refundable once activated. Please read the product description carefully before purchasing. If you have any questions, contact our team to confirm the configuration before you order.

4. Service & Support

• Service stability: we work to keep the Services stable and carry out scheduled maintenance to maintain and improve our infrastructure.
• 24/7 technical support: technical support is available 24/7 by ticket at https://www.justg.com/submitticket.php.
• Your data: we do not back up the data on your Services. You are responsible for backing up your own data and for regularly checking that you can restore it.

5. Fair Use of Resources

You may use the resources allocated to your cloud server (VPS), subject to the following limits, which protect the performance of shared infrastructure for all customers.

5.1 Storage I/O. Your VPS must not continuously perform storage I/O operations at more than 100 MiB/s for prolonged periods (4 hours or more). If it does, we will notify you by email. If the excessive storage I/O continues after that notice, we may temporarily suspend the Service until the issue is resolved.

5.2 Network bandwidth. Cloud server ports are shared, and we do not guarantee how much bandwidth each customer can use. You must not use more than 70% of the port bandwidth for prolonged periods, as this affects other customers’ servers. If this happens, we will notify you by email. If the excessive use continues after that notice, we may temporarily suspend the Service until the issue is resolved.

5.3 CPU. Your VPS may use 100% of its CPU resources for short periods. However, the one-hour average CPU load must not exceed 50%. If it does, the CPU resources available to your VPS will be automatically limited to that level, and a notice will appear in the VPS control panel. The limit is lifted automatically once usage returns to the permitted level. We impose no other CPU limits beyond those stated here.

6. Acceptable Use

You must use the Services in accordance with our Acceptable Use Policy, which forms part of these Terms. It describes prohibited activities, your security responsibilities and how violations are handled.

7. Security & Privacy

• Data security: we take reasonable technical and organizational measures to protect our network, our systems and the information we hold.
• Privacy: we do not sell personal data. How we collect, use and protect personal data is described in our Privacy Policy.
• Backups: you are responsible for backing up your own data. We are not liable for any loss of or damage to data stored on your Services.

8. Intellectual Property

All JUSTG services, software, documents and content are protected by copyright and other intellectual property laws. You may not copy, modify, distribute or otherwise use JUSTG intellectual property without authorization. Content you upload remains yours, but you grant JUSTG the rights necessary to deliver the Services.

9. Cookies

Our website uses cookies to keep it working, to improve your experience and to analyze traffic. You can adjust or delete cookies in your browser settings; disabling some cookies may affect certain website functions. See our Privacy Policy for more information.

10. Suspension & Termination

If you violate these Terms or the Acceptable Use Policy, we may suspend or terminate the Services without refund. Depending on the nature and severity of the violation, we may first issue a warning and give you an opportunity to resolve the issue.

Services may also be suspended for non-payment, as described in Section 2, or for exceeding the fair use limits described in Section 5.

11. General Policy

We may modify, update or discontinue any Service at any time.

These Terms may be published in several languages. All language versions are equivalent; if a translation differs from the English version, the English version prevails.
