This is an extract from an archived copy, fetched 13 August 2026. Duolingo didn't author this page for us. It's a snapshot we captured from https://www.duolingo.com/privacy. We hold the whole page and publish this part of it: the sentence a verdict rests on, with the text either side, so you can see it hasn't been lifted out of an exception.

The entry cited this capture from 13 August 2026 until 21 September 2026, when the document was re-read; it now cites the capture of 10 September 2026. This page stays so that anything that linked it still works.

The passage, in context

Paragraph 22 of 156

c. AI Features & Video Call

Duolingo uses Artificial Intelligence ("AI") to help create lessons, matches, and other content within the app, based on users' learning activity. For example, AI might be used to tailor a Spanish lesson to include more words that a user is struggling with, or play a chess match in real-time to adapt to a user's moves.

Duolingo may offer a Video Call feature where you can have an AI-powered spoken conversation with a Duolingo character to practice the language you are learning. Duolingo may also offer other AI-powered features that allow you to send text or audio messages to AI chat companions in a conversational format.

When you interact with Video Call or other AI-enabled features, the text and audio you submit may be shared with AI vendors such as OpenAI and Google. Duolingo's agreements with these AI vendors mean they are not permitted to use any personal information for their own purposes. Additionally, Duolingo may generate, record, and store audio recordings or transcripts of the text and audio you submit, and use these recordings or transcripts for product improvement and personalization purposes, including training and running Duolingo's own artificial intelligence models. Please do not submit any personal, sensitive, or confidential information when using Video Call or other AI features.

Duolingo may also offer a video Math Tutor feature where you can have an AI-powered spoken conversation with a Duolingo character to work on a math problem. Notwithstanding anything else in this section, when you use the Math Tutor feature, your audio may be shared only with Apple for purposes of speech recognition and conversion into a text transcript and is then immediately deleted. Duolingo may retain, use, and share with AI vendors the text transcript as described above.

d. Speaking Activities

Some activities, including Video Call, involve you speaking into the Duolingo app. To recognize speech, your audio may be sent to a third-party provider such as Google, Apple, or Amazon Web Services. Additionally, Duolingo may collect and analyze your speech to help us understand the effectiveness of our lessons and to improve or personalize the product. You may skip speaking activities. You may also choose not to share your audio with us for product improvement purposes within the app Settings. We will not use your audio recordings to develop any voice cloning technology.

Checking the rest of it

The complete page is kept here and isn't republished. It's Duolingo's copyrighted document, and an extract is what a reader needs to check a quotation.
