Terms of Service

Last updated: July 14, 2026

These Terms of Service (“Terms”) govern your access to and use of MADI (Meta Analysis Data Interface), a tool that helps card, comic, and collectible shops scan items, estimate grades and prices, list items to their sales channels, and price customer collections for buy offers. By creating an account or using MADI, you agree to these Terms. If you do not agree, do not use MADI.

MADI uses AI and market data to estimate an item’s identity, condition grade, and price. These are automated estimates from photos and third-party data, not certified grades, appraisals, or financial advice, and they may be wrong. A grade estimated by MADI is not a grade from CGC, PSA, or any grading company, and a suggested price is not a promise of sale value. You are solely responsible for reviewing every listing, grade, price, and buy offer before you rely on it or publish it.

You keep ownership of the photos and listing data you put into MADI. You grant MADI a limited license to process that content solely to provide the service — for example, to analyze photos, generate listings, and publish to the channels you choose. If you connect eBay, Shopify, Anthropic, or PriceCharting, you authorize MADI to act on your behalf with those services using the credentials you provide, which are stored encrypted. How we handle your data is described in our Privacy Policy.

MADI is provided on an “as is” and “as available” basis. We work to keep the service running but do not guarantee it will be uninterrupted, error-free, or that estimates will be accurate. Features may change, and third-party services we rely on may change or become unavailable.

To the fullest extent permitted by law, MADI and its operator are not liable for indirect, incidental, or consequential damages, or for lost profits, lost sales, mispriced or misgraded items, or losses arising from your use of estimates or from any connected channel. Our total liability for any claim is limited to the amount you paid for MADI in the three months before the claim.

You may stop using MADI and close your account at any time. We may suspend or terminate access if you violate these Terms or use the service in a way that risks harm to MADI, other users, or third parties. On termination, your right to use the service ends; certain data is deleted automatically as described in the Privacy Policy.

We may update these Terms from time to time. If we make material changes, we will update the date above and, where appropriate, notify you. Continuing to use MADI after changes take effect means you accept the updated Terms.

Questions about these Terms can be directed to the shop owner who operates your MADI account, or to MADI support.
