The clause establishes a contractual restriction on AI vendors' use of personal information, limiting their use to Duolingo's purposes rather than the vendors' own.
Interpretive note: The clause states a contractual outcome ('Duolingo's agreements mean they are not permitted') but the enforceability and scope of those agreements are not described. The clause does not specify what 'their own purposes' excludes or includes beyond the quoted language.
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.
