Third-Party Advertising Data Sharing

High severity
Share 𝕏 Share in Share

What it is

eBay shares your personal data with third-party advertising partners and analytics providers to deliver targeted advertisements both on and off the eBay platform.

Why it matters

Your browsing behavior, purchase history, and personal data are shared with external companies for commercial advertising purposes, which may not be what you expect when you shop on eBay.

Institutional analysis (Compliance & legal intelligence)

Advertising data sharing likely constitutes 'selling' or 'sharing' personal information under CCPA/CPRA, requiring a clear opt-out mechanism. Under GDPR, consent or legitimate interests must be established for each advertising partner; legal teams should verify that consent signals are passed correctly to downstream processors.

Consumer impact

eBay collects an extensive range of personal data including financial details, government IDs, biometric data (for sellers), browsing behavior, and location data, and shares this information with advertising partners, payment processors, and other third parties for targeted marketing and fraud detection. Consumers' messages sent through eBay's platform may be filtered and scanned, and their data may be transferred internationally across eBay's global affiliates. You can manage your communication preferences, advertising settings, and submit data rights requests through eBay's Privacy Center at https://www.ebayinc.com/company/privacy-center/privacy-contact/.

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
    Navigate to your eBay account's Communication Preferences or Privacy Settings. For California residents, locate the 'Do Not Sell or Share My Personal Information' link in eBay's Regional Privacy Disclosures section and submit the opt-out request.

Applicable agencies
