How This Briefing Works
This dossier opens with key findings, then maps the gap between what Marchex discloses and what BLACKOUT observed at runtime. From there: what it means for your organization, what to do about it, and the detection evidence underneath. BLACKOUT observes runtime browser behavior and cites the regulations that address each pattern — legal determinations are your counsel's call.

Briefing
Marchex deploys call intelligence and behavioral analytics that begin data collection before user consent. Session recording and behavioral biometrics capture visitor interactions across phone and web touchpoints. Cross-site tracking enables persistent visitor identification through communication channels.
What This Means For You
Sales teams lose call attribution visibility if Marchex is removed. Marketing cannot connect phone conversions to campaigns. However, retention creates liability: class action exposure for voice biometric collection without BIPA compliance, regulatory fines for processing special category data pre-consent, reputational damage if call recordings leak containing customer PII.
Risk Channel Breakdown
Distorts attribution data
Behavioral profiles from voice and web sessions feed competitive intelligence platforms.
Expands attack surface
Pre-consent activation of session recording and behavioral biometrics creates regulatory exposure under GDPR Article 9 (biometric data) and CPRA sensitive data provisions.
