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.
View change record →The updated policy removes explicit language stating that Android users and website users are not subject to audio collection for product improvement purposes. Previously, the policy authorized audio collection only from iOS users, with an explicit carve-out for Android and web users. The revised language now states that all users may choose not to share audio within app Settings, suggesting audio collection may now occur across all platforms unless the opt-out mechanism is used. The practical operational effect of this change depends on whether Duolingo implements audio collection on Android and web platforms, which the policy change does not explicitly confirm. You can decline audio sharing for product improvement by adjusting the setting within the app.
View change record →The updated policy now discloses a new Math Tutor feature that processes audio through Apple for transcription; audio is deleted but text transcripts may be retained and shared with AI vendors. Duolingo also clarified that IP addresses may be retained longer than 30 days for paying subscribers specifically for payment processing and fraud prevention. The policy changed the Video Call feature from 'Duolingo offers' to 'Duolingo may offer', clarifying it is optional. You can disable FullStory and Session Replay activity recording using the Tracking toggle in app Settings.
