Marketplaces are data controllers for both buyers and sellers, making their privacy obligations more complex than single-sided platforms. You're responsible for how third-party sellers handle buyer data transacted through your platform, and you must disclose data sharing between parties, dispute resolution processes, and rating/review systems. The United States has a sectoral approach to data privacy β no single federal law covers all businesses, but multiple laws apply depending on your industry and the data you collect.

The United States has a sectoral approach to data privacy β no single federal law covers all businesses, but multiple laws apply depending on your industry and the data you collect. Key federal laws include COPPA (children's data), HIPAA (health data), GLBA (financial data), and CAN-SPAM (email marketing). FTC enforcement can result in significant penalties for deceptive data practices.

Data typically collected by Marketplace businesses: buyer and seller profiles, transaction history, messaging data, payment details, reviews and ratings, ID verification data
A Cookie Policy is best practice for US, even if not strictly mandated. It demonstrates transparency and builds user trust. For Marketplace businesses using analytics or advertising tools, it is strongly recommended.
A typical Marketplace website uses: essential session cookies, analytics cookies (Google Analytics, etc.), functional preference cookies, and marketing/advertising cookies if you run paid campaigns. Each type must be disclosed in your Cookie Policy with its purpose.
Under US, a Cookie Policy alone is not sufficient. A consent mechanism is recommended for analytics and marketing cookies to align with global privacy best practices.
