Instagram

Instagram invades privacy via its in-app browser, injecting tracking code into every link you click, while monitoring camera and microphone usage patterns and analyzing every image you view. Over 50 data points are collected per user session, and the platform integrates more seamlessly with Meta's ad network than #2 Facebook does. This granular, unsolicited surveillance makes Instagram a standout danger, as it harvests intimate user data—like interests in medical topics—without transparent disclosure.
