The Audiobooks app downloads chapters to your device so they load faster. Over time this can take up storage space. You can free it up in just a few taps — your progress and points are not affected.
How to free up storage
Step 1. Tap the More tab in the bottom right of the app.
Step 2. Tap Free Up Storage. This will remove downloaded chapters from your device.
Your progress is safe. Freeing up storage only removes locally downloaded files. You can re-download and read any chapter again at any time — your listening progress and points stay exactly where they are.
