Privacy Policy

Last updated: February 13, 2026

Grade.IQ ("we", "our", or "us") is operated by Marceus.tcg. This Privacy Policy explains how we collect, use, and protect your information when you use the Grade.IQ mobile application ("the App").

1. Information We Collect

Images you provide: When you use Grade.IQ to grade a card, you capture or upload images of your cards. These images are sent to our servers for AI analysis and are not stored permanently. Images are processed in real-time and discarded after your grading results are generated.

Grading history: Your grading results are stored locally on your device using local storage. We do not have access to your grading history.

Subscription information: If you subscribe to a paid plan, payment processing is handled entirely by Apple through the App Store. We do not collect, store, or have access to your payment details (credit card numbers, bank information, etc.). We use RevenueCat to manage subscription status, which assigns an anonymous user identifier.

Usage data: We track your monthly grading count locally on your device to manage free tier limits. This data is not sent to our servers.

2. How We Use Your Information

To analyse card images and provide estimated grades using AI technology
To retrieve market pricing data for your cards from public pricing databases
To manage your subscription status and grading limits

3. Third-Party Services

We use the following third-party services:

OpenAI: Card images are sent to OpenAI's API for AI-powered condition analysis. Images are processed according to OpenAI's Privacy Policy.
RevenueCat: Manages subscription status using anonymous identifiers. See RevenueCat's Privacy Policy.
TCGPlayer (via TCGCSV): We retrieve publicly available market pricing data. No personal information is shared with this service.
Apple App Store: Handles all payment processing for subscriptions.

4. Data Storage and Security

Your grading history and preferences are stored locally on your device. Card images are transmitted securely via HTTPS to our servers for processing and are not retained after analysis is complete. We do not maintain user accounts or databases of personal information.

5. Children's Privacy

Grade.IQ is suitable for all ages. We do not knowingly collect personal information from children under the age of 13. The App does not require account creation or the submission of personal information.

6. Your Rights

Since we store your data locally on your device and do not maintain user accounts:

You can delete your grading history at any time from the App's settings
Uninstalling the App removes all locally stored data
You can manage or cancel your subscription through your Apple ID settings

7. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date. We encourage you to review this policy periodically.
