TikTok Shares Your Data More Than Any Other Social Media App, Study Says

According to a recent study published by mobile marketing company URL Genius, YouTube and TikTok track users' personal data more than any other social media apps. However, while YouTube mostly collects your personal data for its own purposes to serve you more relevant ads, TikTok mostly allows third-party trackers to collect your data -- 'and from there, it's hard to say what happens with it,' reports CNBC. From the report: With third-party trackers, it's essentially impossible to know who's tracking your data or what information they're collecting, from which posts you interact with -- and how long you spend on each one -- to your physical location and any other personal information you share with the app. As the study noted, third-party trackers can track your activity on other sites even after you leave the app.

To conduct the study, URL Genius used the Record App Activity feature from Apple's iOS to count how many different domains track a user's activity across 10 different social media apps -- YouTube, TikTok, Twitter, Telegram, LinkedIn, Instagram, Facebook, Snapchat, Messenger and Whatsapp -- over the course of one visit, before you even log into your account. YouTube and TikTok topped the other apps with 14 network contacts apiece, significantly higher than the study's average number of six network contacts per app. Those numbers are all probably higher for users who are logged into accounts on those apps, the study noted.

Ten of YouTube's trackers were first-party network contacts, meaning the platform was tracking user activity for its own purposes. Four of the contacts were from third-party domains, meaning the social platform was allowing a handful of mystery outside parties to collect information and track user activity. For TikTok, the results were even more mysterious: 13 of the 14 network contacts on the popular social media app were from third parties. The third-party tracking still happened even when users didn't opt into allowing tracking in each app's settings, according to the study. 'Consumers are currently unable to see what data is shared with third-party networks, or how their data will be used,' the report's authors wrote.
