Sub-processors

Last updated: August 6, 2026

Transistor uses a small number of third-party service providers to deliver the Services. This page lists the Sub-processors that may process Personal Data on behalf of our customers, as required by our Data Processing Agreement.

We update this page before a new Sub-processor begins processing Personal Data, so that you have an opportunity to object. If you would like to be told when this page changes, write to mail@transistor.fm.

Transistor is established in the United States. Personal Data transferred to Transistor from the EEA, UK, or Switzerland is transferred under the Standard Contractual Clauses incorporated into our DPA. Each Sub-processor below is bound by written data protection terms no less protective than that DPA.

Notes

  • Distribution platforms are not Sub-processors. When you publish a podcast, your RSS feed and media files are retrieved by directories and apps such as Apple Podcasts, Spotify, YouTube, and Amazon Music. Those platforms act as independent controllers with respect to any data they collect from their own users. Transistor does not control and is not responsible for their processing.

  • Dynamic ad insertion. Where you enable dynamic ads through a third-party ad platform, that platform's processing of listener data is governed by your agreement with it, not by this list.
