OfferUp, Inc.

OfferUp is a large mobile-first marketplace in the United States designed for local buyers and sellers to transact, similar to Craigslist or Facebook Marketplace. Users create profiles and can list a wide variety of new or used goods, from furniture and electronics to cars, primarily for in-person exchanges. While not a traditional data broker, the platform exposes personal information through public profiles, user ratings, and communications necessary to arrange transactions. The nature of facilitating in-person meetings between strangers introduces risks of theft, fraud, and personal safety issues. Furthermore, OfferUp collects user data including location, IP address, and device information, and for payment processing, its partner Stripe collects highly sensitive data like Social Security Numbers and government IDs. To protect themselves, individuals should limit the personal details shared in their profiles and listings, communicate exclusively through the app's secure messaging, and arrange to meet in designated safe public places.
