If you delete a podcast from your ZenCast account, that show's RSS feed will immediately cease to be published. The RSS feed is the file that podcast listening apps search to get information about your show, so when they can't find this file, they'll normally assume the show doesn't exist anymore and unpublish your podcast from their platform.
If you cancel your ZenCast account entirely, the same thing will happen to all podcasts under your account, their RSS feeds will be unpublished at the end of your current subscription period.
So, over time, each listening app will eventually take note of the missing RSS feed and delete your shows and episodes from their library automatically.
What if my podcast isn't automatically deleted from some platforms?
In some cases, most notably with Spotify, your podcast might not automatically be removed. This is because they 're-host' your show, or in other words they store their own copy of your podcast files and when the show is deleted from ZenCast, Spotify's copy can still exist.
To get this removed from Spotify you may have to log in to the Spotify for Podcasters dashboard and manually delete your show there, or contact their help channels.
Occasionally, other platforms may also display content from your deleted show. The difference is that, unlike Spotify, most platforms will not store their own version of your files, so that content will no longer be playable even though the listing appears publicly. Again, the best course of action in this is to reach out to the platform directly and ask them to remove the listing.
