TrustDevice is a lightweight library for determining device uniqueness and risk identification. It can create a device identifier based on basic device information. Tis will remain the same after uninstalling and reinstalling or clearing app data. This demo application shows you the details gathered and thus is useful for getting detailed device information. As a side effect it shows you what data an app can access without having any permissions – and could transfer it to „some servers“ if it had just the INTERNET permission.
