A Portuguese-based consumer protection organization has filed a lawsuit against the short-video app TikTok for allegedly allowing minors under 13 to register for an account without parental consent and failing to take protective measures for them.

The case was filed a day after the British privacy watchdog said that TikTok had been penalised 12.7 million pounds ($15.81 million) for violating data protection laws, including using children’s personal information without their parents’ permission.

Australia, the United States, France, and other Western nations have recently banned TikTok on government devices amid growing security worries that China could exploit the Beijing-based business, owned by ByteDance Ltd, to gather users’ data.

In a statement, the nonprofit organization Ius Omnibus pleaded with a Lisbon judge to “put an end to the criminal action” and mandate the financial recompense of individuals harmed, claiming that TikTok “profits from children under the age of 13, taking advantage of their special fragility.”

Although TikTok did not immediately react to a request for comment, it did provide a statement to the Portuguese newspaper Publico stating that the “utmost attention” was placed on preserving its users’ data.

As per Ius Omnibus TikTok ultimately collects and processes children’s personal data in violation of the EU’s general data protection regulation, Portugal’s constitution, and the law against unfair business practices.

Despite having an age restriction, the group claimed TikTok “does not deploy methods to prevent registration” by users under the age of 13.

It alleges that consumers older than 13 are also the victims of “misleading business practices” and that some personal data is utilized without their express consent in a separate complaint.
