What TikTok’s New Data Sharing Terms Mean for You

In early 2025, TikTok quietly updated its privacy policy for users in the U.S. and Europe. The changes, buried deep in the fine print, outline broader data-sharing arrangements with its parent company ByteDance, as well as unnamed “business partners.” Privacy advocates warn that these updates could expose users to greater tracking, profiling, and potential government access.

What Changed?

The updated policy allows TikTok to:

• Share behavioral and biometric data (such as voiceprints and face geometry) with affiliates and service providers.
• Use personal data to develop “AI-driven personalization engines” that extend beyond TikTok to other apps owned by ByteDance.
• Transfer data internationally, including to jurisdictions with weaker privacy protections than the EU or the U.S.

Why It Matters

These changes could result in:

• More detailed tracking of user activity, both on and off TikTok.
• User data contributing to AI systems whose purposes are not always disclosed.
• Greater risk of data exposure in the event of government demands or cyberattacks.

Experts like Nina Patel, director of the nonprofit Privacy for All, point out:

“TikTok’s privacy update highlights how platforms increasingly blur the lines between entertainment, surveillance, and AI development. Most users will never see these changes, but they could have real-world consequences for their privacy and security.”

What You Can Do

• Review your TikTok privacy settings, limit ad personalization, and data sharing where possible.
• Be mindful of what you post, especially content involving minors or sensitive topics.
• Consider alternatives; some smaller social platforms offer stronger privacy protections.

The Bottom Line

TikTok’s privacy policy is part of a wider trend of apps collecting more data for AI development and ad targeting. Understanding these policies, and your rights is key to protecting yourself in an increasingly connected world.
