Fix the Flex only reads pages on flexstudent.nu.edu.pk that you are already logged into. All data (course names, credit hours, marks, attendance) is stored locally on your device using the browser's storage API. No data is transmitted to any third-party server, analytics service, or the developer. The only network requests made are same-origin calls back to flexstudent.nu.edu.pk pages you're already viewing. No remote code is loaded.
