Clear limits for a decision-support tool.

Using the service

You may use Graded Card Value to manage a collection that you are authorized to manage. You are responsible for your Google account, the accuracy of submitted information, and lawful use of third-party content and links.

Evidence and valuations

Values depend on the evidence attached to a card. Market conditions, fees, taxes, shipping, card condition, and buyer behavior can change the amount realized. Automated research produces review leads, not verified facts; only evidence you explicitly mark as a verified exact match contributes to Final Value.

User responsibility

You are responsible for confirming card identity, certification details, evidence accuracy, and the permissions granted to connected services.

Availability

Google and external data providers may be unavailable. The app fails closed when authentication, storage, or evidence cannot be verified. Features may change or be suspended to protect users, data, or the service.

Prohibited use

Do not use the service to misrepresent cards, evidence, ownership, grades, or market value; interfere with security controls; automate abusive traffic; or violate another person's rights or applicable law.

Data and third-party services

Google identity, Drive, Cloud Vision, Gemini, and Search features are governed by their applicable terms as well as the Privacy Policy. You keep responsibility for and control of the records and images stored in your Drive. Deleting or disconnecting an external account can make app features or data unavailable.
