Duolingo updated its privacy policy on April 21, 2026 to add details about a new Math Tutor AI feature and to modify how audio and transcript data are handled. For Math Tutor, audio is shared with Apple for speech recognition and then deleted, while text transcripts may be retained and shared with AI vendors. The policy also added language clarifying that IP addresses may be retained longer for payment processing and fraud prevention when users have paid subscriptions.
Consumers: If you pay for Duolingo, your IP address may be kept longer than the standard 30 days for handling payments and preventing fraud.
Consumers: When you use Math Tutor, your spoken audio goes to Apple to be converted to text; the audio is then deleted but Duolingo may keep and share the written transcript with AI vendors.
The updated policy now discloses a new Math Tutor feature that processes audio through Apple for transcription; audio is deleted but text transcripts may be retained and shared with AI vendors. Duolingo also clarified that IP addresses may be retained longer than 30 days for paying subscribers specifically for payment processing and fraud prevention. The policy changed the Video Call feature from 'Duolingo offers' to 'Duolingo may offer', clarifying it is optional. You can disable FullStory and Session Replay activity recording using the Tracking toggle in app Settings.
