Meta uses the data it collects from your Threads activity to show you personalized ads and content across its family of apps, including Facebook and Instagram, not just within Threads itself.

The policy states that Threads data contributes to Meta's cross-platform advertising and personalization systems, meaning activity on Threads may inform what ads and content you see on Facebook, Instagram, and other Meta services.
Interpretive note: The specific lawful basis asserted by Meta for cross-product advertising data use in EU jurisdictions is not detailed in the Threads supplemental policy itself; it references the broader Meta Privacy Policy, creating some ambiguity about the precise legal basis applicable to Threads-specific data flows.

"We use the information we collect to send you ads and other commercial and sponsored content. We use the information we have to deliver our products, including to personalize features and content and make suggestions for you on and off our products. We share information across the Meta Companies.— Excerpt from Threads's Threads Privacy Policy
REGULATORY LANDSCAPE: Cross-product data use for advertising engages GDPR purpose limitation and data minimization principles, requiring that data collected on Threads be used only for purposes compatible with those disclosed at collection. The Irish Data Protection Commission has supervisory authority for Meta's EU operations. Under CCPA and CPRA, this cross-context behavioral advertising constitutes sharing of personal information, triggering opt-out rights. The FTC has authority over unfair or deceptive practices related to advertising data use. GOVERNANCE EXPOSURE: High. The breadth of cross-product data use for advertising, flowing from a newly launched social platform into Meta's established advertising infrastructure, creates significant GDPR and CCPA compliance obligations. Lawful basis documentation for EU users, particularly regarding legitimate interest assertions for advertising, and opt-out mechanism accessibility for CCPA purposes should be reviewed. JURISDICTION FLAGS: EU and EEA users face the most complex regulatory exposure, as GDPR requires a valid lawful basis for each purpose of processing, and advertising profiling is subject to heightened scrutiny. California residents have an explicit opt-out right for sharing of personal information for cross-context behavioral advertising under CPRA. Other US state privacy laws including Virginia, Colorado, and Connecticut also provide opt-out rights for targeted advertising. CONTRACT AND VENDOR IMPLICATIONS: Businesses running paid advertising on Meta platforms should be aware that Threads data contributes to the audience targeting infrastructure they use. Data processing agreements with Meta should be reviewed to confirm that Threads data flows are covered by existing contractual frameworks. COMPLIANCE CONSIDERATIONS: Compliance teams should verify that CCPA opt-out signals, including Global Privacy Control, are honored for Threads data used in cross-context behavioral advertising. GDPR compliance teams should confirm that consent or legitimate interest assessments cover Threads-specific data flows. Internal privacy notices and employee communications should be updated to reflect Threads data use if applicable.
