We may collect account details (name, email, phone, shipping address), order and consignment records, offers you submit, messages you send us, device/browser data, cookies for site access and sessions, and images of cards you upload or that we scan for vault processing.

We use data to operate the marketplace and vault, process submissions, identify and list cards, communicate about orders and consignments, improve tools, prevent fraud/abuse, and comply with law.

Scans and photos of cards are identified first by GCS free-path systems (OCR, catalog match, and fingerprints). Residual third-party AI/vision providers may run only when that path cannot finish a card. Depending on configuration, that residual may include providers such as Google Gemini, Anthropic Claude, xAI Grok, and specialty card-recognition APIs (for example CardSight or Ximilar). Images may also be stored for inventory, listings, fingerprint matching, and quality review. Do not upload images you do not have rights to use.

We may share data with service providers that help us run the platform, including for example: hosting (e.g. Vercel), data stores (e.g. Upstash/Redis or similar), email (e.g. Resend), payments (e.g. Stripe), analytics (e.g. Google Analytics), shipping carriers when you request shipment, AI/vision APIs as above, and marketplace channels you authorize (e.g. eBay listing tools). We may also share with authorities when required. We do not sell personal information as a consumer data broker.

We use cookies and similar storage for site password gates (when enabled), admin and account sessions, cart/preferences, basic security, and (when configured) **Google Analytics 4** to understand aggregate traffic, popular pages, and referral sources. Analytics may use cookies or similar identifiers and process IP/device data under Google’s terms; we use this for product and marketing decisions, not to sell personal data. You can block cookies or use browser controls / Google’s ad settings where available; some features may not work without cookies.

We retain account, order, offer, and vault records as needed for operations, tax, and dispute resolution. Scan images and contact messages may be retained for operational history and then deleted or archived.

We use reasonable technical and organizational measures, but no method of transmission or storage is 100% secure.

Contact support@globalcardshow.com to update account details or request deletion where applicable (subject to legal and operational retention needs).

Services are not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact us so we can delete it.
