Terms of Service

M3IOX LLC (USA) & Xencore M3IOX India Private Limited (India) · GradeX · Last updated: May 18, 2026 · Effective: May 18, 2026

By using GradeX you agree to these terms. Plain English summary: use GradeX fairly, pay for what you use, don't abuse the system. We'll keep the service running and your data safe.

1. THE SERVICE & WHO PROVIDES IT

GradeX ("the Service") is an AI-powered academic grading tool that helps teachers grade handwritten math papers using AI assistance. Teachers retain full authority over all final grades.

The Service is provided by M3IOX LLC (a company registered in Wyoming, USA) to customers in the United States and the rest of the world, and by Xencore M3IOX India Private Limited (a company registered in Uttar Pradesh, India; CIN U72502UP2022PTC163098) to customers in India. The two companies are independently incorporated and under common ownership. In these terms, "we", "us" and "our" refer to whichever entity provides the Service to you based on your billing country.

GradeX is a tool to assist educators — not to replace them. All AI-generated grades are drafts that must be reviewed and approved by the teacher before being considered final.

2. ACCOUNTS

You must provide accurate information when creating an account. You are responsible for maintaining the security of your account credentials. Notify us immediately at contact@m3iox.com if you suspect unauthorized access.

One organization account per school or tutoring business. You may not create multiple free accounts to circumvent plan limits.

3. PLANS & PAYMENT

GradeX offers a free plan and paid subscription plans. Paid plans are billed monthly in advance. Prices are shown in USD (USA & rest of world, via Stripe) or INR + 18% GST (India, via Razorpay).

USA & rest of world: Billed by M3IOX LLC via Stripe. Charges appear as GRADEX.M3IOX.COM on your statement.

India customers: Billed by Xencore M3IOX India Private Limited via Razorpay. Prices shown are exclusive of 18% GST (SAC Code 9983); the total charged includes GST. A GST invoice is provided on request to contact@m3iox.com.

4. REFUND & CANCELLATION POLICY

GradeX offers a free plan, so you can evaluate the Service fully before paying. Paid plans are billed monthly in advance.

Cancellation: You may cancel at any time from the Billing & Upgrade section of your account. On cancellation, your plan remains active until the end of the current paid billing month, and you will not be charged again after that.

Refunds: Because a free plan is available for evaluation, paid subscription fees are non-refundable once a billing month has started. Cancelling stops future renewals; it does not refund the current month.

Billing errors: If you were charged in error or have a billing problem, contact contact@m3iox.com within 7 days of the charge and we will review it. Approved refunds are returned to the original payment method within 5–7 business days.

The full Refund & Cancellation Policy is available at gradex.m3iox.com/refund.html.

5. PLAN LIMITS

Each plan includes limits on students, teacher accounts, and papers graded per day. Limits are enforced at the organization level. Exceeding limits requires upgrading your plan or purchasing Extra Credits.

We reserve the right to suspend accounts that attempt to circumvent plan limits through technical means.

6. ACCEPTABLE USE

You may use GradeX only for legitimate educational grading purposes. You may not:

7. STUDENT DATA & TEACHER RESPONSIBILITY

You are responsible for obtaining any necessary consent from students, parents, or guardians before uploading their work to GradeX, in accordance with laws applicable in your jurisdiction (FERPA in USA, DPDP Act in India, GDPR in EU, etc.).

GradeX provides the technical infrastructure. You are the data controller for your students' information.

8. AI ACCURACY DISCLAIMER

GradeX AI grading is a drafting tool. AI-generated scores and feedback may contain errors. Teachers must review all AI grades before finalizing. The GradeX operating entity is not liable for grading errors that result from relying on unreviewed AI output.

Accuracy improves with clear, well-lit photos. Poor image quality may result in lower accuracy.

9. INTELLECTUAL PROPERTY

The GradeX platform, including its AI grading architecture (provisional patent filed), code, and branding, is owned by M3IOX LLC and licensed to Xencore M3IOX India Private Limited for operation in India.

Content you upload (student papers, answer keys) remains yours. You grant the GradeX operating entity a limited license to process this content solely to provide the grading service.

GradeX never collects training data without explicit opt-in. Org administrators can enable or disable AI improvement contributions in Settings → Privacy → Training Data Consent; the default is OFF. When opted in, we collect pseudonymized grading samples — student work and teacher-verified rubric scores — with all org and session identifiers replaced by one-way HMAC hashes that cannot be reversed without our internal salt. We do not associate samples with any specific student, teacher, or organization in the training corpus. You can withdraw consent at any time and request deletion of any samples collected from your org by emailing contact@m3iox.com.

10. SERVICE AVAILABILITY

We aim for high availability but do not guarantee 100% uptime. Planned maintenance will be communicated in advance where possible. We are not liable for losses caused by service interruptions.

11. LIMITATION OF LIABILITY

The total liability of the GradeX operating entity (M3IOX LLC or Xencore M3IOX India Private Limited, as applicable to you) for any claim related to GradeX is limited to the amount you paid for the Service in the 3 months prior to the claim. We are not liable for indirect, incidental, or consequential damages.

12. TERMINATION

You may cancel your account at any time via the Billing & Upgrade section. We may suspend accounts that violate these terms with reasonable notice where possible. Upon termination, your data is retained for 90 days before deletion.

13. CHANGES TO TERMS

We will notify you by email at least 14 days before material changes. Continued use after changes constitutes acceptance.

14. GOVERNING LAW

For customers billed by M3IOX LLC, these terms are governed by the laws of the State of Wyoming, USA, and disputes will be resolved through binding arbitration, except where prohibited by local law.

For customers billed by Xencore M3IOX India Private Limited, these terms are governed by the laws of India, and the courts at Agra, Uttar Pradesh shall have jurisdiction. Indian consumer protection laws (the Consumer Protection Act, 2019) apply where they provide greater protection than these terms.
