Is my RSS feed private, or can anyone find it?
Yes — every subscriber gets a unique feed URL keyed to a long random token that only you receive. The URL is never indexed, never published, and not discoverable through the public web. The same token is what your podcast app uses to authenticate, so anyone who somehow guessed it could still listen — treat it like a password and do not paste it publicly.
When your subscription is cancelled, the feed deactivates. Past tokens stop serving audio, so a stale URL from a previous cycle will not continue to work. Each new active subscription generates a fresh token pair.
