Privacy Policy

Welcome to CardChecker (“we,” “our,” or “us”). We are committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application and web service (collectively, the “Service”).

By using the Service, you agree to the collection and use of information in accordance with this policy.

2.1 Information You Provide

• Your email address, when you create an account
• Card images you upload for analysis
• Collection and watchlist data you create

2.2 Automatically Collected Information

• Device information (device type, operating system)
• Server logs of requests to our service (time, address requested, IP address), kept for security and troubleshooting
• Camera access data (only when you actively use the scanner)

2.3 Pre-order List

If you join the CardChecker Studio pre-order list on our website, we store your email address, the phone type you chose (if any), the link that brought you to the page and your browser language. We use them only to email you when pre-orders open and to understand which channels people come from. No payment is taken. To be removed, write to support@cardchecker.app.

2.4 Website Analytics

On our website (not in the app) we measure how the site is used. Vercel Web Analytics counts page visits, the page that sent you and your country and device type. Microsoft Clarity records how pages are used — clicks, scrolling and mouse movement — so we can see which parts are read and where people get stuck. Clarity hides what you type into form fields. Neither tool sets cookies on our site or follows you across other websites. Microsoft processes Clarity data under its privacy statement at privacy.microsoft.com.

We use the collected information to:

• Provide card identification, pricing, and grading services
• Maintain your collection and watchlist
• Manage your account and your free grade allowance
• Improve our AI models and service quality
• Send service emails, such as sign-in codes
• Ensure security and prevent fraud

When you upload card images for analysis, the images are processed by our AI systems to identify cards and assess condition. Images are:

• Sent to our secure servers for processing
• Analyzed using computer vision and AI models (including third-party AI services such as Google Gemini and Anthropic Claude)
• Not stored when sent for identification, except as described in 4.1
• When sent for grading, kept on our processing server only so the result can show them, and deleted automatically: the straightened card within 30 days, the close-up crops within 90 days
• Not shared with other users unless you explicitly create a public report

4.1 Improving card recognition

If the Help improve recognitionsetting in the app is on, we keep a copy of the card from each scan and use it to train and test our card recognition. The setting is shown to you before your first scan — switched on in the Android app, switched off on iPhone — and you can change it at any time in the app’s Account tab. Once it is off, nothing further is kept.

• We keep only the part of your photo that our system identified as the card, with a thin margin around it, and only when it is confident it recognised a card. Anything visible on the card itself, such as a reflection in a sleeve, is part of that image. We remove all image metadata, including location.
• Each copy is stored with the result our system gave. Copies may be reviewed by an AI service acting on our behalf, Anthropic Claude, to check that result, and copies that turn out not to show a card are deleted when reviewed. Anthropic may process them in the United States under its data processing terms, which include the European Commission’s Standard Contractual Clauses, and may not use them to train its own models.
• We do not record which account, device or IP address a kept copy came from. Because of that, we cannot find or delete one person’s copies on request.
• Kept copies are deleted after 24 months.

We do this on the basis of our legitimate interest in making card recognition more accurate (GDPR Art. 6(1)(f)). You have the right to object at any time; switching the setting off does exactly that.

We may share your information with:

• Service Providers: Third-party services that help us operate (cloud hosting, AI processing, payment processing)
• CardMarket: We retrieve public pricing data from CardMarket; your personal data is not shared with them
• Legal Requirements: When required by law or to protect our rights

We do not sell your personal information to third parties.

We implement appropriate technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the Internet is 100% secure.

We retain your data for as long as your account is active or as needed to provide services. You may delete your account and all data associated with it at any time, from the Account tab in the app or without installing it at all. Card images follow the timelines in Section 4.

How to delete your account and what gets deleted →

Depending on your jurisdiction, you may have the right to:

• Access and receive a copy of your personal data
• Rectify inaccurate or incomplete data
• Request deletion of your personal data — do it yourself here
• Object to or restrict processing of your data
• Data portability
• Withdraw consent at any time

To exercise these rights, please contact us at the email below.

Our app may request access to your device camera to scan trading cards. Camera access is used solely for card image capture and is never activated without your explicit action. You can revoke camera permissions at any time through your device settings.

Our Service is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If we become aware that we have collected data from a child under 13, we will take steps to delete that information.

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the “Last updated” date. Continued use of the Service after changes constitutes acceptance of the updated policy.

If you have questions about this Privacy Policy, please contact us at support@cardchecker.app.
