Last updated: May 2026

These Terms of Service (“Terms”) govern your access to and use of the QuantumOS X3 platform, software, and services (collectively, the “Service”) provided by QuantumOS X3 (“Company”, “we”, “us”, or “our”). By accessing or using the Service, you agree to be bound by these Terms.

1. Acceptance of Terms

By creating an account or using the Service, you agree to these Terms and our Privacy Policy. If you are accepting on behalf of a company or other legal entity, you represent that you have authority to bind that entity. If you do not agree to these Terms, do not use the Service.

2. Accounts

You must provide accurate and complete information when creating an account. You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account. Notify us immediately at support@qosx3.com if you suspect unauthorized access. We may suspend or terminate accounts that violate these Terms.

3. Acceptable use

You may use the Service only for lawful purposes and in accordance with these Terms. You must not:

• Use the Service to transmit spam, illegal content, or material that infringes third-party rights
• Attempt to gain unauthorized access to any part of the Service or its related systems
• Reverse-engineer, decompile, or disassemble any component of the Service
• Use the Service to process or store prohibited categories of sensitive personal data without a signed DPA
• Resell, sublicense, or white-label the Service without our prior written consent
• Engage in activities that degrade performance for other customers

4. Fees & billing

Paid plans are billed monthly or annually in advance. Fees are non-refundable except as required by law or as explicitly stated in your order form. We will provide at least 30 days' notice of price changes. Overage charges (where applicable) are billed at the end of each billing period. You are responsible for all applicable taxes.

If payment fails, we will retry up to three times over 7 days and notify you by email. Accounts more than 14 days overdue may be suspended until payment is resolved.

5. Service availability

We target the uptime levels specified in our Service Level Agreement (“SLA”), available at /status. Scheduled maintenance windows will be communicated with at least 72 hours' notice except in emergency situations. The SLA applies to all paid plans as specified in each plan's terms.

6. Intellectual property

The Service, including all software, documentation, and content created by us, is owned by QuantumOS X3 and protected by copyright, trademark, and other intellectual property laws. These Terms grant you a limited, non-exclusive, non-transferable license to use the Service for your internal business purposes. Your data remains yours — we claim no ownership over your products, customer data, or business content.

7. Termination

You may cancel your account at any time from your Command settings. We may suspend or terminate your access for material breach of these Terms with notice where practical. Upon termination, you may export all your data for 90 days. After that period, data is deleted per our data retention policy.

8. Disclaimers

THE SERVICE IS PROVIDED “AS IS” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, QUANTUMOS X3 WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, WHETHER INCURRED DIRECTLY OR INDIRECTLY. OUR AGGREGATE LIABILITY FOR ANY CLAIMS ARISING UNDER THESE TERMS WILL NOT EXCEED THE AMOUNTS YOU PAID TO US IN THE 12 MONTHS PRIOR TO THE EVENT GIVING RISE TO LIABILITY.

10. Governing law & disputes

These Terms are governed by and construed in accordance with the laws of the State of Delaware, without regard to conflict of law provisions. Any disputes arising under these Terms shall be resolved by binding arbitration under AAA Commercial Arbitration Rules, except that either party may seek injunctive relief in any court of competent jurisdiction.

11. Changes to Terms

We may modify these Terms at any time. We will provide at least 30 days' notice of material changes via email and in-product notice. Continued use of the Service after the effective date of changes constitutes your acceptance of the revised Terms.
