Why audio files are not uploaded

The reason AudioDock does not upload your files is simple: there is no server-side processing step to upload them to. The browser's File API hands the raw bytes of your file directly to the JavaScript running in your tab, and that is where they are read, edited, and exported. Nothing in that pipeline reaches across the network.

This is a deliberate design choice, not a setting you have to find and enable. It means there is no upload progress bar, no queue, and no maximum file size dictated by a server — the only practical limit is your device's available memory.

If you want to confirm it for yourself, you can. Open your browser's developer tools, switch to the Network tab, and run any tool on a file. You will not see your audio being sent anywhere, because it never is. That verifiability is the whole point.
