Terms of Service

Last updated: May 6, 2026

1. Acceptance of Terms

By accessing or using teachwithcolin ("the Service"), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.

2. Description of Service

teachwithcolin is an AI-powered essay grading platform. The Service allows teachers to upload student essays, have them graded by AI against a rubric, and receive feedback reports and gradebooks.

3. Account and Authentication

• You sign in using an email address and a password you create at registration. During the beta period, registration is gated by an invite code.
• You must verify your email address before grading essays.
• You are responsible for keeping your password confidential and for the security of the email account associated with your sign-in.
• You must not share your account access with unauthorized users.
• Notify us immediately if you believe your account has been compromised.

4. Acceptable Use

You agree to:

• Use the Service only for its intended purpose of grading student essays.
• Not upload content that is illegal, harmful, or violates third-party rights.
• Not attempt to circumvent security measures, rate limits, or access controls.
• Not use the Service to process data you are not authorized to handle.
• Comply with all applicable laws, including FERPA if you handle student records.

5. Content Ownership

• You retain all rights to content you upload (essays, rubrics).
• AI-generated grading feedback and reports are provided for your use and do not transfer intellectual property rights.
• We do not claim ownership of your uploaded content or generated outputs.

6. AI-Generated Content

Grading results are generated by AI (Anthropic Claude) and should be reviewed by the teacher before being used for official grading purposes. The Service is a tool to assist teachers, not a replacement for professional judgment.

• AI-generated grades and feedback may contain errors or inconsistencies.
• You are responsible for reviewing and validating all AI output before sharing with students.
• We do not guarantee the accuracy of AI-generated grades.

7. File Handling

• You upload student essays as a ZIP archive (max 500 MB). Supported file types are .docx, .pdf, and .txt.
• Uploaded files are stored on our hosting provider's persistent volume only as long as needed for grading and are automatically purged 30 days after the batch completes.
• Generated reports (per-student .docx and .xlsx gradebook) are made available for download directly from the Service.
• See our Privacy Policy for the full data-handling and retention details.

8. Service Availability

• We aim to provide reliable service but do not guarantee uninterrupted availability.
• We may perform maintenance that temporarily affects service access.
• We reserve the right to modify, suspend, or discontinue the Service with reasonable notice.

9. Billing and Credits

• Each graded essay consumes one credit. New accounts receive a welcome credit bonus.
• Additional credits are purchased in packs via Stripe Checkout. Pack sizes and pricing are shown in-app at the time of purchase.
• During the beta period, billing enforcement may be relaxed; usage is always tracked regardless of whether enforcement is active.
• Purchases are processed by Stripe and are subject to Stripe's terms. Refund and dispute requests should be directed to us first; chargebacks may result in account suspension.
• Credits are non-transferable and have no cash value outside the Service.

10. Limitation of Liability

The Service is provided "as is" without warranties of any kind. To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Service, including but not limited to inaccurate grading results, data loss, or service interruptions.

11. Termination

We may suspend or terminate your access to the Service if you violate these Terms. You may stop using the Service at any time and may request account deletion by contacting support.

12. Changes to Terms

We may update these Terms from time to time. Continued use of the Service after changes constitutes acceptance of the updated Terms.
