Terms of Service

Last updated: 2026

Note: This is a plain-language summary and not legal advice. Have your attorney review before public launch.

1. Acceptance

By creating an account or using any Dotto Card Co. service (grading, marketplace, Dotto Life, live shows), you agree to these Terms of Service and our Privacy Policy.

2. Eligibility

You must be at least 18 years old (or the age of majority in your jurisdiction) to create an account or transact on the platform.

3. Accounts

You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account. Notify us immediately of any unauthorized use.

4. Grading services

Grading opinions are subjective assessments performed by trained graders using proprietary AI assistance. Grades are final upon slabbing and are not guaranteed to match any other grading company's opinion.

5. Marketplace

Dotto operates as a venue between buyers and sellers. Sellers are responsible for accurate listings and timely shipment. Dotto's Buyer Protection program governs disputes and refunds — see the Buyer Protection page.

Platform fees: 7% for free members, lower for paid members. Standard payment processing fees also apply.

6. Prohibited conduct

  • Fraud, misrepresentation, or counterfeit goods
  • Off-platform payment circumvention
  • Harassment or abusive behavior in chat, comments, or messages
  • Scraping, reverse engineering, or automated abuse of the platform

7. Termination

We may suspend or terminate accounts that violate these Terms. You may close your account at any time via your profile settings.

8. Disclaimers & liability

The service is provided "as is." To the maximum extent permitted by law, Dotto's liability is limited to the amounts paid by you to Dotto in the 12 months preceding the claim.

9. Changes

We may update these Terms from time to time. Continued use of the platform after changes take effect constitutes acceptance.
