Private RSS delivery
Castline gives each feed a private RSS URL. Podcast apps can subscribe to the feed while the media remains protected by tokenized URLs.
Private podcast feed
Private podcast feeds for audio you want to keep personal.
Create private RSS feeds for saved audio, generated episodes, and small-group listening without publishing a public podcast.
Token rotation
When you rotate a private feed token, old RSS and media URLs stop working. This gives you a simple recovery path when a link has been shared too widely.
Not public podcast hosting
Castline is designed for listen-later inboxes and private podcast feeds, not YouTube downloading, video conversion, or public podcast distribution.
