This provision establishes the operational scope of data sharing for advertising purposes and identifies the categories of third parties who receive access to user information. It defines a core data flow mechanism within Duolingo's business model.
The updated privacy policy no longer contains explicit language stating that Duolingo uses cookies to enhance user experience and analyze performance, or that it shares user information with social media, advertising, and analytics partners. The policy also no longer displays a 'Do Not Sell My Personal Information' button. These removals may affect the transparency of Duolingo's practices as disclosed in the policy document itself, though actual data practices may remain unchanged. Users should review the complete updated privacy policy to understand current disclosures about data collection and sharing.
