Every scroll, pause, and rewatch tells TikTok something about you. Here's what the app actually collects and what your rights are under California law.

TikTok has over a billion users worldwide. In the US, roughly two-thirds of teenagers use it regularly. But most of those teens have no idea what data TikTok is collecting while they scroll — or where that data ends up.
This article breaks it down simply: what TikTok collects, how it uses that data, and what rights you have as a California resident to push back.
What you give it directly: Your name, email, phone number, birthday, and profile photo. Any messages you send. Any content you post, including drafts you never publish.
What it tracks automatically: Every video you watch and for how long, which videos you rewatch, which ones you skip, your search history, your device, your IP address, your approximate location, and the content of your clipboard — meaning if you copy something and open TikTok, it can read what you copied.
What it infers: Using all of the above, TikTok builds a behavioral profile inferring your age range, interests, political leanings, mental health status, and purchasing intent.
TikTok is owned by ByteDance, a Chinese company. Congress has argued that ByteDance's ties to the Chinese government mean user data could be accessed by Chinese authorities. TikTok launched "Project Texas" to store all US user data on servers managed by Oracle — but whether this fully addresses the concern is debated by security experts.
TikTok also shares data with advertising partners. When you see a targeted ad, that targeting is based on your behavioral profile being matched against advertiser criteria.
As a California resident you have the right to know what data TikTok has, request a copy, request deletion, and opt out of data sharing for advertising. TikTok must honor requests within 45 days. Submit through Settings → Privacy → Personalization and Data.
TikTok is not uniquely evil — Instagram, YouTube, and Snapchat all collect comparable data. What makes TikTok distinctive is the precision of its behavioral inference engine, widely considered the most sophisticated in consumer social media. You don't have to delete the app. But as a Californian, you have the legal right to know what it knows about you.
