Podcast Analytics displays the total number of unique devices that played content from a show or episode. Podcast Analytics begins gathering data as soon as users play content in the Podcasts app (iOS 11 or later) or iTunes 12.7 or later (macOS and Windows). For more information, see Podcast Analytics Requirements.
Additionally, you may obtain download information from the server that hosts your podcast episodes. Contact your server administrator or web host for details on configuring podcast analytics. Many Apple Podcast Hosting Partners provide reporting.
Podcast Analytics is a data visualization tool that gives you insight into how users are listening to your shows and episodes in Apple Podcasts.
Podcasts app for iOS pauses downloads of episodes from podcasts which the user hasn't listened to. Episode auto-downloading stops 15 days after a user last views that podcast or plays an episode on any device the user is signed into. Episode auto-downloading also stops after 5 new episodes are unplayed on a single device.
iTunes desktop also has protections against unwanted downloads. After 15 days and 5 unplayed new episodes, new podcast episodes stop auto-downloading. After 45 days, the podcast metadata stops updating.
