Libsyn is a US platform for hosting and distributing podcasts. Creators upload audio or video, and Libsyn stores the files, manages the feed and passes episodes on to services such as Apple Podcasts and Spotify. The platform also provides listener statistics and tools for connecting advertising and sponsorship to a show. It is delivered as SaaS through the browser; self-hosting is not possible and the software is not open source.
Libsyn is based in the United States. According to its privacy policy, data is stored and processed in the United States and may be made available to US government agencies under legal process. No separate EU region is mentioned. The policy does include a GDPR section: for content that users supply themselves Libsyn acts as processor, and for the website and service itself as controller. For European organisations this means podcast files and listener data fall under US jurisdiction. Public episodes are meant to be distributed widely, but account and management data deserve a deliberate assessment.
