Is my file uploaded to a server?

No. The file is opened by your browser and displayed on this page. It is never uploaded, stored or logged — close the tab and it’s gone.

Does it work on my phone?

Yes. It works in any modern browser on iPhone, Android, Windows, Mac and Linux, with nothing to install.
