Yes, Castbox plays private podcast feeds. Copy your private RSS URL, open Castbox, paste it into the Discover or Search field, and tap Subscribe. Castbox is free to download and use, and manual RSS imports are part of the core app. One caveat: make sure your feed URL is unique, active, and issued by a host that respects privacy tags.
TL;DR:
- If a feed fails, test its URL in a browser, remove stray spaces, refresh My Library, and ask the creator for a replacement.
- Past reporting documented private feeds republished through Castbox, so creators should use unique, revocable URLs and hosts that honor tags blocking public indexing.
- A free Castbox account syncs subscriptions between a phone and tablet, while offline downloads and manual RSS imports remain available without a paid plan.
- If episodes stream but will not save, check Castbox's download preferences and app permissions before replacing a working feed URL.
- Treat the feed URL like a password; unique listener links let hosts revoke a leak without disabling access for every subscriber.

How do you add a private RSS feed to Castbox?
The steps are short and usually take only a little time. A help article from Hello Audio describes the same workflow, and hosts such as Castos document it too.
- Copy the full RSS URL from the email or member page you received. Leave out any extra spaces before or after it.
- Open Castbox and tap Discover or Search.
- Paste the URL into the search field and tap Search.
- Tap the podcast artwork when it appears, then tap Subscribe.
- Open My Library to find the show. Episodes are ready to stream or download, and new ones arrive automatically.
Give Castbox a couple of minutes to process a brand-new feed. If you sign into a free Castbox account, your subscription follows you from your phone to your tablet.
Pro Tip: Paste the link straight from the email instead of retyping it. One missing character is the most common reason a private feed fails to load.
What should you do when Castbox won't load your feed?
Most failures come down to a bad link or a rushed refresh. Work through these checks in order:
- Paste the link into a web browser first. A valid feed shows raw XML or a page from your host; an error page means the link itself is broken.
- Make sure you pasted into the Discover or Search field, and that no space or line break sits at either end of the URL.
- Force-close Castbox, reopen it, and pull down to refresh My Library. Then wait a few minutes.
- Check your download preferences and app permissions if episodes stream but won't save offline.
- Ask the creator for a fresh URL. Links get regenerated or revoked more often than people expect, and an old one simply stops working.
How does Castbox handle private feeds and privacy?
Castbox is an open RSS aggregator. It pulls in content through open feeds, and when you add a URL yourself, the show lands in your own library rather than in public discovery.
That is the intended behavior, but the record is mixed. Reporting has documented that private subscriber feeds became publicly available through Castbox, and publishers asked for the copies to be removed. Podnews described how Castbox struggled to respect tags meant to block indexing. Incidents like these are rare, but worth a quick check.
Reporting has documented cases where private feeds were re-published through Castbox, with publishers asking for removal. The Verge covered it. The practical lesson: confirm your host protects the feed, not just the app.
A short checklist for listeners and creators:
- The host issues a unique URL per listener, so one leaked link can be revoked alone.
- The feed carries tags asking apps not to index it.
- Tokenized or authenticated feeds are used where the host supports them.
- For strict confidentiality, ask the host about monitoring and anti-leak measures.
Which Castbox features help private-feed listeners?
Castbox gives you more than a paste box. These features matter most for private shows:
- Free access: the app has no mandatory subscription, and manual RSS import and offline downloads are part of the core experience.
- Offline downloads: save episodes before a car trip or a flight.
- Custom playlists: mix private episodes with public shows you already follow.
- Playback controls: adjust speed and skip silence, handy for bedtime listening.
- AI-powered search: find spoken content inside audio.
Some hosts offer a one-click "add to app" button, and Podfan notes that this works when the host provides the integration. When there is no button, the manual paste method always works.
Why do we say to treat your feed link like a password?
We publish weekly personalized superhero episodes for kids, and we deliver each family's show to their email through a private podcast feed. The link to the feed is the key to your child's show, so keep it between you and the people you choose to share it with.
Our advice to parents is simple: paste the link into Castbox as described above, then create a free account so the show syncs to every device in your house. If a link goes missing or you think it was shared by accident, contact us. For the creator side of this, we explain our approach in our guide to a privacy-first family podcast.

FAQ
Is there a free version of Castbox?
Yes. Castbox is free to download on iOS and Android, with no mandatory subscription for its core features. Manual RSS imports for private podcasts are part of that free experience.
How do I add a private podcast in Castbox?
Copy your private RSS URL, open Discover or Search in Castbox, and paste it in. Tap Search, then Subscribe, and the show appears in My Library.
Why is my private podcast not showing up in Castbox?
The link is usually incomplete, expired, or pasted with a stray space. Test it in a browser, refresh My Library after a few minutes, and ask the creator for a new URL if it still fails.
Is a private podcast in Castbox really private?
Castbox places a manually added feed in your own library, but past reporting shows some private feeds were indexed publicly. Choose a host that issues unique, protected URLs and respects no-index tags.
