Where Does Castbox Store Offline Episodes?
Castbox podcast library with offline episodes and account sync on mobile.
Last updated
Castbox stores subscriptions, custom playlists and listening progress on the account with episode downloads in app private storage for offline. Its in-audio search index is server side; your shelf is the portable part.
Storage fills through subscriptions auto downloading plus manual pins. Cleanup rules evict played episodes when configured. New logins restore the library shape immediately while audio refetches per device.
Where Castbox stores this, by platform
App-private storage (episodes downloaded per show rules)
Auto download counts and Wi-Fi only toggles per subscription. Zen mode and player settings live in app data. Clearing app data drops episodes; the account shelf restores.
App sandbox (episodes downloaded per show rules)
Same model on iPhone with background downloads. Deleting the app clears audio while subscriptions, playlists and progress persist on the account.
Frequently asked questions
why is Castbox using so much storage
Auto downloads across many shows plus manual pins. Lower per show episode counts, enable played cleanup, and prune manually downloaded backlogs from the downloads screen.
how do I move Castbox to a new phone
Sign into the same account: subscriptions, playlists and progress sync down. Reconfigure auto download rules and fetch episodes fresh on Wi-Fi.
