Duolingo removed three sentences from its privacy policy on May 27, 2026. The removed language disclosed that the website uses cookies to enhance user experience and analyze performance, that Duolingo shares user information with social media, advertising, and analytics partners, and a button labeled 'Do Not Sell My Personal Information'. The removal of these explicit disclosures means the policy no longer contains these particular statements about cookie use and data sharing partnerships.
The updated privacy policy no longer contains explicit language stating that Duolingo uses cookies to enhance user experience and analyze performance, or that it shares user information with social media, advertising, and analytics partners. The policy also no longer displays a 'Do Not Sell My Personal Information' button. These removals may affect the transparency of Duolingo's practices as disclosed in the policy document itself, though actual data practices may remain unchanged. Users should review the complete updated privacy policy to understand current disclosures about data collection and sharing.
The removal of explicit disclosures about cookie use and data sharing partnerships reduces the transparency statements previously made in Duolingo's policy. The removal of the Do Not Sell button is operationally significant because CCPA and similar state laws may require companies to provide consumers with an opt-out mechanism. The absence of these disclosures in the updated policy creates potential compliance questions depending on whether replacement language exists elsewhere and whether actual data practices have changed.

→ Users will not see the explicit disclosure that their information is shared with advertising and analytics partners in the privacy policy.
→ California residents may not have clear visibility into a Do Not Sell mechanism if no replacement was provided in the updated policy.

Track changes →Duolingo removed three sentences disclosing cookie use, advertising partner data sharing, and a Do Not Sell button from its privacy policy on May 27, 2026. This change may create compliance exposure under CCPA (California Consumer Privacy Act), which requires California consumers to have the ability to opt out of the sale or sharing of personal information. The removal of explicit disclosures without replacement language warrants review by legal and privacy teams to determine whether the policy remains compliant with applicable data protection laws and whether actual practices have changed. The operative question is whether these disclosures were required by law or contractually necessary, and whether their removal violates regulatory expectations in jurisdictions where Duolingo operates.
