Researcher claims Tik Tok able to track users' keystrokes

New research from a former Google engineer warns TikTok has the ability to track user keystrokes in its Web browser, a claim that is alarming privacy advocates but receiving pushback from the platform's parent company.

The research from Felix Krause, a Vienna-based privacy researcher, did not explain how TikTok used the capability. But Krause warned TikTok had built functionality to track users' online habits if it chose to do so.

"This was an active choice the company made," Krause said. "This is a non-trivial engineering task. This does not happen by mistake or randomly."
