The Irish Data Protection Commission (DPC) has imposed a staggering €345 million fine on TikTok for breaching the European Union’s General Data Protection Regulation (GDPR) concerning the handling of children’s data. This investigation, initiated in September 2021, scrutinized TikTok’s processing of personal data of users aged between 13 and 17 during a specific time frame.
Here are the key findings and implications of this significant penalty.
In response to these violations, the DPC imposed a substantial €345 million fine and mandated TikTok to align its data processing practices with GDPR standards within three months.
In a statement on its website, TikTok expressed disagreement with the DPC’s decision. The company argued that the criticisms pertain to features and settings that were in place three years ago, which have since been modified by automatically setting all accounts of users under 16 to private by default. It remains uncertain whether TikTok intends to appeal the ruling.
Additionally, TikTok announced plans to introduce a redesigned account registration process for new users aged 16 and 17, pre-selecting private accounts. This update is scheduled for later this month. TikTok currently boasts approximately 134 million monthly users within the European Union.
