What it is

Poshmark allows outside advertising companies to place tracking technologies on the platform and collect your data over time and across different websites to show you targeted ads.

Consumer impact (what this means for users)

Your behavioral data — including what you browse, like, and purchase on Poshmark — is accessible to third-party advertisers who can combine it with data from other platforms to profile you for targeted ads. California residents have the right to opt out of this sharing as it may constitute a 'sale' or 'sharing' under CPRA.

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.

Opt Out of Arbitration

Send an email to privacy@poshmark.com requesting to opt out of the sale and sharing of your personal information for targeted advertising. Include your registered email address and state 'Do Not Sell or Share My Personal Information' in the subject line.
