TikTok leads the way of social media firms tracking people the most

Social media giants are tracking your every move, scooping up huge amounts of personal data from armies of unwitting users - but some are guilty of hoovering up more information than others. TikTok is the biggest data harvester, collecting more than any other social media app or messaging service, according to a study by cyber security firm Internet 2.0. Owned by Chinese firm ByteDance, the popular video-sharing app has around a billion active users worldwide. But it has more than double the number of trackers in its source code than the industry average. TikTok's tracking software surreptitiously gathers data about users to fine tune the algorithm running its main feed.
