According to the privacy policy, if a Duolingo Max user utilizes artificial-intelligence (AI) features, a copy of their text or audio data will be shared with vendors such as [[OpenAI]].<ref>{{Cite web|url=https://www.duolingo.com/privacy|title=Privacy Policy|work=Duolingo|date=2024-09-11|access-date=2025-03-26|archive-url=https://web.archive.org/web/20250124094802/https://www.duolingo.com/privacy|archive-date=2025-01-24|url-status=live}}</ref> This is also similar for non-AI features, as Duolingo "may also collect and analyze your speech to help [it] understand the effectiveness of [its] lessons and to improve the product", though the data are anonymized. 

It is also mentioned that when completing a lesson, a video of a user's lesson "will be logged by a service called FullStory". This service records usage patterns, device specs, and learning activity, and is only disabled by default for child users. Opting out requires going to FullStory's website.

The policy states the app works with third-party advertising networks to personalize advertising, such as with [[Google]], [[Meta]], [[OAuth]], and [[Unity]]. Personalized advertising can be disabled in the app's settings.

The Exodus Privacy project lists as many as 13 tracking, advertising and analytics service libraries being present in the Android version of the app.<ref>{{Cite web|url=https://reports.exodus-privacy.eu.org/de/reports/com.duolingo/latest/|title=Report for com.duolingo 6.22.3|work=exodus|date=2025-03-25|access-date=2025-03-26|archive-url=https://web.archive.org/web/20250326193207/https://reports.exodus-privacy.eu.org/de/reports/com.duolingo/latest/|archive-date=2025-03-26|url-status=live}}</ref> The app does not work for more than about one lesson without internet access, hence turning off internet access is not an option to prevent data exfiltration. The [https://trackercontrol.org/ F-Droid version of Tracker Control] can help with blocking some of the traffic to these services without impacting the functionality of the app.
