It’s great that the app can play internet radio but without a proper browser it gets difficult to use the feature.
Open-source apps use radio-browser.info as an open index of internet radio that received contributions from the community. See Shortwave – Apps for GNOME for example.
I think adding a simple search feature that can fetch radios from this index and save their info locally for use would be great.
No they are users’s server and data, they can have have parental control there to prevent access.
Here’s it’s direct internet source in the app without control.
