TikTok — Policy Change
Executive Summary
ByteDance completed its $1 billion acquisition of Musical.ly and merged the platform into TikTok, consolidating over 100 million users under a single app and privacy policy. The merger unified two distinct data collection regimes, with ByteDance gaining access to all Musical.ly user data including that of a predominantly young US user base.
What Happened
On August 2, 2018, Chinese company ByteDance completed its acquisition of Musical.ly (announced in November 2017) and merged it into TikTok. Musical.ly users found their app replaced with TikTok's logo and name, with all existing users and their accounts automatically migrated to the TikTok platform. Musical.ly had reached 100 million monthly active users at the time of the merger, and all user data was absorbed into ByteDance's TikTok system.
Who Is Affected
All 100 million Musical.ly monthly active users were affected, with their accounts and data automatically transferred to TikTok without requiring individual consent for the migration. The user base was predominantly composed of teenagers in the United States who had been using Musical.ly primarily for lip-syncing and dance videos. These users now fall under TikTok's privacy policy and data practices rather than Musical.ly's previous terms.
Why It Matters
This merger consolidated two distinct platforms and their data collection practices under a single Chinese-owned company, giving ByteDance access to a large base of young American users and their personal information. The automatic migration meant users had no choice but to accept TikTok's terms or stop using the service entirely, as their existing Musical.ly app was replaced. The scale of the merger, involving 100 million users, represented a significant expansion of ByteDance's data collection footprint in the US market.
What You Should Do
Former Musical.ly users should review TikTok's privacy policy and terms of service to understand how their data is now being collected and used. Users uncomfortable with the new data practices can delete their TikTok account and request deletion of their data. Parents of teen users should discuss the platform change with their children and review privacy settings together.
