Information From Children
While Quizlet is intended for users age 13 and over, if a child requests access to our website we accommodate them by offering a limited feature set and restricted website experience that removes certain features. We offer this restricted experience (“Child Account”) for accounts of all users below the age of 13 and for some users below the age of 16 where applicable under local law.
To create a Child Account, Quizlet requires the user to submit a date of birth, username and email address. We collect a parent’s email address from a child under the age of consent if they attempt to register in order to notify the parent of their child’s use of Quizlet and, where required, to seek parental consent for use of that data. We do not sell information from Child Accounts. We may share or distribute information from Child Accounts as described in this section and this Privacy Notice, including with parents in order to provide notice of use and gather parental consent, with third parties to support internal operations, and to provide the restricted experience on the Service to the Child Account.
We do not condition a child's participation or access to any activity on Quizlet on the child providing any personally-identifying information or any more information than is reasonably necessary for that activity. We may use aggregated or de-identified information about children for research, analysis, marketing and other commercial purposes.
Third Party Service Providers. We use a restricted version of Google Analytics to limit data sharing and tracking on areas of our site and mobile apps that are accessed by children.
Parental Rights. Parents and legal guardians of children under 13 can consent to collection and use of a child's personal information without consenting to the disclosure of that information to third parties. Parents or guardians can review information their children under 13 have contributed to Quizlet by accessing their child's account via password reset. Parents can also request that Quizlet delete that information and refuse to allow Quizlet to collect further information from their children by contacting Quizlet at firstname.lastname@example.org. Learn more about this in our Managing your Account section below. Quizlet may ask additional questions or take other steps to verify the identity of a parent or guardian before responding to a request to review or delete a child's information or a request to refuse further collection from a child.

Quizlet complies with the Privacy Shield Principles for all onward transfers of personal data from the EU, United Kingdom and Switzerland, including the onward transfer liability provisions. For example, we may use standard contractual clauses when we transfer your personal data to third parties outside the EEA or adopt other means to ensure that adequate safeguards are applied to your personal data, such as a relevant third party’s Privacy Shield certification or binding corporate rules (approved by EU data protection authorities and put in place to protect your personal data).

In certain situations, we may be required to disclose personal data in response to lawful requests by public authorities, including to meet national security or law enforcement requirements.
