Medium severity
Share 𝕏 Share in Share

What it is

Poshmark shares your personal information — including browsing behavior, purchase history, and device data — with third-party advertising and analytics companies to show you targeted ads.

Why it matters

This sharing can result in your personal data being used by companies you have no direct relationship with, and it may constitute a 'sale' of data under some state privacy laws.

Institutional analysis (Compliance & legal intelligence)

Broad sharing of behavioral and commercial data with advertising partners may trigger 'sale' or 'sharing' definitions under CCPA/CPRA, requiring opt-out mechanisms and contractual safeguards with all downstream recipients.

Consumer impact

Poshmark collects extensive personal data including identifiers, payment information, location data, and behavioral data, and shares it with third-party advertising and analytics partners, which may affect your privacy and the ads you see. Users have limited control over how their data is used for targeted advertising unless they actively exercise opt-out rights. You can opt out of the sale or sharing of your personal information by visiting Poshmark's privacy settings or submitting a request through their designated privacy portal.

What you can do

⚠️ These actions may provide transparency or partial mitigation but may not fully address the underlying issue. Effectiveness varies by jurisdiction and individual circumstances.
