Terms of Service

You must be at least 18 and authorised by your school or institution to use Excellent on behalf of students. You are responsible for activity in your account and for keeping your credentials safe.

Each workspace belongs to the school or teacher who created it. Owners control membership and can remove members at any time.

Use Excellent only for grading your own students' work. Do not upload personal data of anyone who is not a student-of-record for the course you teach. Do not upload content you do not have permission to process.

Do not attempt to reverse-engineer the Service, scrape it, abuse rate limits, or use it to build a competing product. Do not upload content that is illegal, defamatory, or violates someone else's rights.

Excellent's AI suggests scores and feedback. The teacher always reviews and can override any score before it is final — the AI assists, the teacher decides.

We make no guarantee that AI-suggested scores are correct. Use your professional judgment; final grading decisions and their academic consequences are yours.

Excellent is pay-per-use, with no subscription. Creating an account requires a one-time activation payment of $10 or €10, which is credited to your account in full as 20 credits. One credit pays for the first grading of one submitted exam or homework paper (US $0.50 / €0.50); re-grading a paper that has already been graded is free. You can top up your balance at any time in any multiple of one credit above the posted minimum, paying in USD or EUR via our payment processor (Stripe). If a grading fails and cannot be delivered, its credit is automatically returned to your balance.

Money-back guarantee: within 7 days of creating your account you may cancel and receive a full refund of everything you have paid, provided you complete the cancellation questionnaire — the feedback is the condition of the guarantee. After the 7-day window, cancelling refunds only your unused credit balance; corrections already delivered are not refundable. Instead of a cash refund, you may choose to convert unused credits into a partner gift voucher where offered. Cash refunds always go back to the original payment method, in the original payment currency, and typically take 5–10 business days to appear. Cancellation closes your account once the request is processed.

We may change features and pricing on reasonable notice. Material changes will not retroactively reduce credits you have already bought — a credit you paid for keeps paying for one correction.

The Service is provided “as is” without warranties of any kind, to the maximum extent permitted by law. We do not warrant that grading will be error-free, uninterrupted, or fit for any particular academic standard.

To the maximum extent permitted by law, our aggregate liability for any claim relating to the Service is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms excludes liability that cannot be excluded by law (including, in the EU, liability for gross negligence or willful misconduct).

You can stop using the Service and delete your workspace at any time from settings. We may suspend or terminate accounts that violate these terms, or close the Service on reasonable notice. On termination, we will help you export your data on request and will delete remaining data per the retention defaults in our Privacy Policy.

These terms are governed by the laws of [Governing Jurisdiction]. Disputes will be resolved in the competent courts of that jurisdiction, without prejudice to mandatory consumer-protection rights you have under your local law (including EU consumer law).
