The Indie Dev Life Podcast is hosted on a Linode server I control. Episodes are hosted there too. I don't use any 3rd-party services (Libsyn, Squarespace, etc) and there's no tracking code anywhere on the site.
When you visit the site, or download an episode in a podcast player, your device's IP (Internet Protocol) address may be logged. This information is not stored permanently and is rotated out after a period of time. Your device or podcast app might additionally send information about whether you've subscribed to the podcast or include other technical information. This information is used to estimate subscriber counts and perform basic technical security measures (blocking malicious IPs, etc).
Indie Dev Life doesn't track you and no personally identifiable information is stored or recorded.
