The updated policy now discloses that audio collection for product improvement applies to all users across all platforms (iOS, Android, and web), whereas previously the policy stated audio was collected only from iOS users. Android and web users are now subject to audio collection for product improvement purposes. All users can opt out of audio sharing within app Settings.
View change record →The updated policy introduces a new Session Replay service that logs user activity alongside FullStory, capturing clicks, mouse movements, scrolling, typing, device information, navigation, and learning activity. Both services can be disabled using the Tracking toggle in app Settings, and both are automatically disabled for child users. The new Math Tutor feature shares audio with Apple for speech recognition and immediate deletion, but retains and shares text transcripts with AI vendors. For payment processing and fraud prevention, Duolingo may retain IP addresses beyond the standard 30-day period. You can disable both FullStory and Session Replay activity recording by toggling the Tracking setting within the app.
