The updated policy now states that all users may opt out of audio sharing for product improvement within app Settings, without specifying which platforms this applies to.

Previous text 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.

Previous text Duolingo modified its audio collection and sharing policy on May 27, 2026. Previously, the policy stated that audio sharing for product improvement could be declined on iOS devices specifically, and that Android users and website users were not subject to audio collection for this purpose. The updated policy removes the device-specific distinction and the explicit statement that Android and website users are excluded, stating instead that all users may choose not to share audio for product improvement within app Settings. This change broadens the stated scope of audio collection to potentially include all platforms, while simultaneously offering a uniform opt-out mechanism.
