Card Deal Finder is a private sports-card resale research application. It stores only the information required to operate listing searches, valuation, alerts, and compliance workflows.
The application may store active listing identifiers, listing titles, prices, shipping information, condition, seller username, seller feedback, item location, listing images and URLs, price history, user-created search rules, valuation results, and alert history.
Stored information is used solely to identify and evaluate sports-card purchase opportunities, prevent duplicate alerts, track price changes, and comply with marketplace requirements. The application does not sell personal data or provide it to advertisers.
The application receives and processes eBay Marketplace Account Deletion notifications. When eBay provides a matching user identifier, associated seller-linked listing records are deleted.
Dashboard access is protected by authentication. API keys and passwords are stored as deployment secrets rather than in source control. Listing and valuation records are retained only while useful for the research workflow or required for compliance.
Questions about this application or its data handling may be sent to the email address associated with the eBay developer application.
