“Duolingo may process and share your personal information for the purpose of providing you with personalized advertising. To provide personalized advertising, we may work with a variety of marketing analytics service providers, website analysis firms, and third-party advertising networks, such as Unity, Meta, LiftOff, Pangle, Moloco, and Google. These third-party advertising service providers collect and use personal information about your visits to and use of the Service, as well as other websites, in order to serve you with advertisements and content tailored to meet your preferences and likely interests, better understand ad effectiveness, and for market research purposes. You can opt out of receiving personalized advertising within the app Settings. In addition, your mobile devices may offer settings that let you make choices about the collection, use, and transfer of mobile app information for personalized ads (for example, Apple iOS’ Advertising ID and Google Android’s Advertising ID). Users in certain jurisdictions (including the European Union and United Kingdom) are opted out of personalized advertising by default, but may opt in. Please note that opting out of personalized advertising does not prevent the display of all advertisements to you. Certain Duolingo subscriptions may offer an ad-free experience.”Open citation

“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.”Open citation
