Apparently, there is a skill for that now. You can ask your Amazon Alexa to delete the recordings of your voice automatically.

The company had originally stated that Alexa would save your voice commands to help improve their services; however, some people are worried about privacy concerns.

Before this new service the Amazon Alexa is now offering, you'd have to head inside of the settings and delete all of those recording manually.

You can now have Alexa delete those chats after three to 18 months. This change can be found in the settings.
