FTC settles with Musical.ly, now TikTok, for $5.7M, over the app's violation of US child privacy laws; TikTok's app updates with a new UX for users under 13
A significant FTC ruling issued today will see video app TikTok fined $5.7 million for violating U.S. children's privacy laws …
Context & Ripple Effects
This 2019 settlement was the first major regulatory reckoning for TikTok's handling of children's data: the FTC hit the company — then still carrying its Musical.ly legacy — with a $5.7M penalty and forced a separate, restricted app experience for users under 13. It set the template for everything that followed, starting with the UK opening its own investigation into TikTok's data practices for young users within months of the fine.
First-order effects
- TikTok pays $5.7M and must ship a distinct UX for under-13 users, walling them off from the main app's data collection and default settings.
- Musical.ly-era accounts and data practices fall under the consent and deletion obligations of US child privacy law, applying directly to the merged TikTok platform.
Second-order effects
- Foreign regulators treat the FTC action as a signal: the UK probe followed almost immediately, and Ireland's DPC later imposed a €345M GDPR fine specifically over children's data handling.
- The settlement establishes child privacy as a recurring legal exposure for TikTok alongside its other liability fronts, including the California litigation over social media harm to minors where Meta and Snap remain defendants.
Third-order effects
- A single $5.7M fine in 2019 scales into a structural compliance burden: by 2026 the same COPPA allegations produce a $400M DOJ settlement, showing child-privacy penalties compounding across a platform's lifetime rather than resolving with one payment.
- If the pattern holds, kids' data handling becomes a permanent, multi-jurisdiction audit surface for consumer apps — with each regulator's action lowering the barrier for the next enforcement agency to act.
The trend: Children's privacy enforcement against social platforms is escalating from one-off national fines to compounding, multi-jurisdiction liabilities that follow a company for years.
