The main reason for the fine was the infringement of the GDPR’s fairness principle in relation to the processing of personal data of children between the ages of 13 and 17 (“Child Users”). The authority has found that the personal data processing by using the Registration Pop-Up and Video Posting Pop-Up did not comply with the GDPR.
According to the authority, TikTok implemented dark patterns, during the registration process, by presetting accounts to be public-by-default at registration, and the opt-out option to make them private was deceptive. TikTok also failed to properly explain in a way that Child Users could understand that, when making a public account, their personal data would be visible to anyone, including registered and unregistered users as well.
In connection to the Video Posting Pop-Up, similar problem has been found. This pop up enables users to change the video’s privacy settings before posting. During the investigation, it was found that the data controller made it difficult for the users to adjust their privacy settings and limit the processing, making it more likely for users to post videos with their pre-set settings.
Furthermore, the age verification measures implemented by TikTok, in order to filter and block the registration of persons under the age of 13, who are prohibited to use the application, were also investigated. The established process is designed to make the registration process cease and block the user from the app, even after re-installing it, if their age was under 13. However, the individuals had not been informed, that they are blocked because of their age.
