Terms of Service

Effective date: July 29, 2026

Last updated: October 16, 2026

1. Who may use the Service

The Service is built for instructors, teaching assistants, and graders at colleges and universities. You must be at least 18 years old. Students do not create accounts and are not parties to these Terms; student coursework is processed on behalf of, and at the direction of, educators and institutions, as described in our Privacy Policy.

K-12 use needs a school agreement. Self-serve accounts, including paid monthly plans, are for college and university courses. Using the Service for a primary or secondary school (K-12) class requires a written agreement between the school and RavenGrader; do not upload work from a K-12 class through a self-serve account.

2. What the Service does, and the instructor’s role

RavenGrader uses AI models to read answer keys and student submissions, generate rubrics, transcribe handwriting, and propose grades and feedback.

AI output is a draft until you approve it. The Service is designed for instructor review: proposed grades, transcriptions, and feedback can be wrong, and the workflow exists so you can catch that. You, not RavenGrader, are responsible for every grade you release to a student or record with your institution. We do not warrant that AI-generated output is accurate, complete, or suitable for release without review.

3. Accounts

Keep your registration information accurate and your credentials secure. Use a named individual account. Do not share logins. You are responsible for activity under your account. Tell us promptly at security@ravengrader.com if you suspect unauthorized access.

4. Plans, pages, billing, and payment

• Pages. Grading uses pages from your balance, one for each page processed. New accounts may receive free pages to try the Service. Payments are handled by our payment processor, Stripe; we do not store your card details.
• Monthly plan. The monthly plan is a subscription. Each time a monthly payment succeeds, the number of pages shown at checkout is added to your balance, and unused pages carry over. The plan renews automatically every month, at the price shown at checkout, until you cancel it.
• Cancelling. You can cancel at any time in Account → Billing. Cancelling stops future charges. The pages you already have stay yours and remain usable until they run out.
• Failed payments. If a renewal payment fails, Stripe may retry it over the following days. No pages are added until a payment succeeds, and if payment keeps failing the subscription may end. Pages already in your balance stay usable.
• Price changes. We may change the monthly price or the number of pages it includes. We will email you at least 30 days before a change applies to your subscription; it takes effect at your first renewal after that notice, and you can cancel before then. A change never affects pages you already hold.
• Automatic credit-back. If a grading run fails or is cancelled, the pages for the unprocessed work are automatically returned to your balance.
• Canvas (LTI) use provisioned by an institution is billed under that institution’s agreement, not through your page balance.
• Pages have no cash value, are not transferable, and expire only if your account is closed.
• For billing problems or refund requests, contact us (Section 13); we review them case by case. Nothing here limits rights you have under applicable law.

5. Acceptable use

You agree not to:

• upload content you lack the right or authority to submit, including student coursework you are not authorized to process;
• use the Service to violate FERPA or any other law, or your institution’s policies;
• probe, disrupt, or overload the Service, or bypass its access controls, rate limits, or credit accounting;
• access another user’s or tenant’s data, or attempt to;
• resell the Service or misrepresent its output as human grading where you are required to disclose otherwise;
• introduce malware or use the Service to build a competing dataset by bulk extraction.

Good-faith security research under our published vulnerability disclosure policy is welcome and is not a violation of this section.

6. Your content and student data

You retain ownership of everything you upload: answer keys, rubrics, student submissions, and course materials (“Customer Content”). You grant us a non-exclusive license to host and process Customer Content solely to provide, secure, and support the Service.

Student educational records are handled as described in our Privacy Policy and any applicable institutional data processing addendum. We act on your (or your institution’s) instructions with respect to those records; we do not sell them or use them for advertising.

7. AI processing

Customer Content is processed by AI models: frontier models from third-party providers acting as our subprocessors, or our own fine-tuned models. Which model handles a task can change over time. The providers that receive Customer Content, and what each receives, are listed in our Privacy Policy, and we add a provider there before sending it anything. Student work goes only to providers whose terms do not allow them to train their models on it. Exam questions, answer keys, and rubric text may also go to a provider whose terms let it use that material to improve its models, as the Privacy Policy describes. If your institution needs its exam materials kept away from such a provider, contact us before deploying.

8. Our intellectual property

The Service (including its software, prompts, grading pipeline, models configuration, and documentation) belongs to RavenGrader and its licensors. These Terms grant you no rights in it beyond use of the Service. If you send us feedback or suggestions, we may use them without obligation to you.

9. Availability, support, and changes

The Service is a continuously deployed application; we ship improvements and fixes without prior notice, and we may add, change, or retire features. We do not promise uninterrupted availability under these Terms. Institutional agreements may contain their own service commitments. Support is available at the contacts in Section 13, and current status is published on our status page.

10. Termination and account deletion

You may delete your account at any time in Account → Privacy. Deletion begins a 30-day reversible grace period, after which your data is permanently destroyed as described in the Privacy Policy (limited billing records are retained in de-identified form).

We may suspend or terminate your access if you materially breach these Terms, if required by law, or to protect the Service or its users, with notice where practicable. Unused pages on an account terminated for material breach are forfeited; otherwise we will work with you in good faith to wind down.

11. Disclaimers and limitation of liability

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WITHOUT LIMITING SECTION 2, WE DO NOT WARRANT THAT AI-GENERATED GRADES, TRANSCRIPTIONS, OR FEEDBACK ARE ACCURATE OR ERROR-FREE.

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (a) NEITHER PARTY IS LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS OR DATA; AND (b) RAVENGRADER’S TOTAL LIABILITY UNDER THESE TERMS IS LIMITED TO THE AMOUNTS YOU PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. THESE LIMITS DO NOT APPLY WHERE THEY CANNOT LAWFULLY BE LIMITED, AND DO NOT LIMIT EITHER PARTY’S OBLIGATIONS UNDER A SEPARATE INSTITUTIONAL AGREEMENT OR DATA PROCESSING ADDENDUM.

12. Indemnity, governing law, and changes

You will defend and indemnify RavenGrader against third-party claims arising from Customer Content you had no right to submit or from your material breach of these Terms.

These Terms are governed by the laws of the State of Delaware, without regard to conflict-of-law rules; courts located in Delaware have exclusive jurisdiction, and each party consents to their venue.

We may update these Terms. For material changes we will give notice (by email or in-product) before they take effect; continued use after the effective date constitutes acceptance. The “Last updated” date above always reflects the current version.
