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.
