"We share information with advertising partners, including advertising networks, measurement companies, and data analytics companies. This sharing helps us show you relevant ads, understand ad effectiveness, and improve our advertising products. We may share identifiers such as your device ID, hashed email address, or phone number with these partners.— Excerpt from Snapchat's Snap Privacy Policy
(1) REGULATORY LANDSCAPE: This provision engages GDPR's requirements for lawful basis for data sharing with third parties, including the need for data processing agreements under Article 28 and potential joint controller arrangements under Article 26 where partners also determine purposes. CCPA and CPRA treat sharing personal data with advertising partners for cross-context behavioral advertising as a 'sale' or 'sharing' triggering opt-out rights. The FTC Act prohibits unfair or deceptive practices in data sharing disclosures. (2) GOVERNANCE EXPOSURE: High. Sharing device identifiers and hashed contact information with advertising networks is a well-established practice but carries elevated regulatory risk given FTC enforcement trends and CPRA's expanded definition of 'sharing.' The policy's disclosure of this practice is relatively clear, but the breadth of the partner ecosystem and the types of identifiers shared warrant close scrutiny. (3) JURISDICTION FLAGS: California residents have a CPRA right to opt out of 'sharing' personal data for cross-context behavioral advertising; Snap must provide a 'Do Not Sell or Share My Personal Information' mechanism. EU/EEA users require consent for behavioral advertising under GDPR and ePrivacy Directive requirements. UK users are subject to UK GDPR and ICO guidance on cookie and tracking technologies. (4) CONTRACT AND VENDOR IMPLICATIONS: Each advertising partner receiving personal data must be covered by a data processing agreement or appropriate controller-to-controller terms; legal teams should assess whether Snap's standard advertiser agreements satisfy GDPR Article 28 and CPRA contractual requirements. The use of hashed identifiers does not eliminate re-identification risk, and partners receiving such data should be contractually prohibited from re-identification. (5) COMPLIANCE CONSIDERATIONS: Compliance teams should verify that the opt-out mechanism for advertising data sharing is prominently accessible, test that it is operationally effective, and confirm that Snap's advertising partner list is current and reflected in data processing records. EU teams should assess whether consent management platform flows adequately capture user consent for advertising data flows.
