Stats: This service collects and aggregates basic information about its listenership, like total download numbers and downloads by date or region.

Tracking: This service may track an individual listener's browsing habits across podcasts and websites. This is typically used to measure advertising conversions. Podbay does not collect any Tracking data.

Dynamic Audio: This service may insert dynamic audio (usually for targeted advertising) into episodes on a per-download or per-stream basis. This could be as basic as factoring in the date or the user's overall region, or when used with Tracking, could be based on more personal user data.
