This website tells you what private information apps might be tracking
A new tool reveals exactly how you’re potentially being tracked, showing how applications like TikTok and Instagram can potentially use JavaScript to view sensitive data, including your address, passwords and credit card information, without your consent.
Apps can inject their JavaScript code into websites, allowing them to monitor how the user is interacting with the app. This can include information on every button or link you tap, keyboard inputs and if screenshots were taken, though each app will vary in what information it collects.
The tool can be found at InAppBrowser.com. All you need to do is open the app you want to check and share the InAppBrowser.com URL somewhere within it — such as DMing the link to a friend or posting it in a comment. From there, you can tap the link and get a report from the website on what scripts are running in the background.
