South Korea is not automatically recognized as providing GDPR-adequate data protection for all transfer scenarios, meaning your EU or UK personal data may be sent abroad without the full protections European law requires.
Poshmark collects extensive personal data including purchase and browsing history, device identifiers, precise location, and social graph information, and shares this data with advertisers, analytics providers, and its South Korean parent company Naver. By default, user profiles and activity are publicly visible on the platform, meaning your buying and selling history can be seen by anyone — not just your connections. You can opt out of the sale or sharing of your personal information for targeted advertising by visiting Poshmark's 'Do Not Sell or Share My Personal Information' link in the app or website footer.
