What it is

Meta takes all the information it has about you from Facebook, Instagram, Messenger, and WhatsApp and combines it into a single profile, which is also enriched with data from outside companies and public sources.

This analysis describes what Meta Ads'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

Why it matters (compliance & governance perspective)

This means a single behavioral or demographic signal from one app — say, a health group you joined on Facebook — can influence what ads you see on Instagram, creating a far more comprehensive and potentially sensitive profile than users expect from any single service.

REGULATORY FRAMEWORK: This provision implicates GDPR Art. 6(1)(f) (legitimate interests as legal basis for cross-platform combination), Art. 9 (special category data that may be inferred through combination), Art. 22 (automated profiling), and Recital 47 (legitimate interests balancing test). The Irish DPC is the lead supervisory authority; all EU/EEA DPAs retain concurrent jurisdiction. CCPA/CPRA §1798.140 (definition of 'sharing' for cross-context behavioral advertising) and §1798.120 (right to opt out of sharing) are also engaged.
