What it is

Coinbase shares your personal data with a broad range of third parties including blockchain analytics companies, advertising networks, and marketing partners — meaning your cryptocurrency transaction history and personal details can be used to track your on-chain activity and serve you targeted ads.

This analysis describes what Coinbase's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology

ConductAtlas Analysis

Institutional analysis (Compliance & governance intelligence)

REGULATORY FRAMEWORK: Sharing personal data for advertising purposes without opt-in consent implicates CCPA/CPRA §1798.120 (right to opt out of sale/sharing) and §1798.121 (sensitive personal information restrictions). Under GDPR Art. 6(1)(f), sharing for advertising requires a legitimate interests assessment that must demonstrably outweigh user interests. Sharing with blockchain analytics firms may constitute processing for law enforcement facilitation purposes, triggering GDPR Art. 6(1)(c) or (e) considerations. FTC Act Section 5 applies to deceptive disclosures about third-party sharing scope.
