I’m using antennapod because I had suspicions based on the ads I was getting that PocketCasts was selling the info of podcasts in my queue/listening history. After that I read their privacy policy to confirm that’s something they do and deleted my account/the app
edit: important to add, I had a paid subscription account and they still appeared to be selling data on me
The docker aio was relatively painless imo. I’ve made it easier in my home server by installing Nextcloud through CasaOS. Makes it very easy
