Why do some tools work differently on mobile browsers?
Mobile browsers have stricter file and folder permissions. For example, individual files can be downloaded easily, while full folder saving may depend on browser support.
How does Google Analytics tracking work here?
Analytics is used only to understand page views and basic tool actions such as opening a tool or clicking a button. Private file content, passwords and personal document data are not tracked.
