Setting up the automatic deletion of Google Assistant data is important from a privacy perspective. When you use your phone or a smart speaker, Google Assistant keeps a lot of data about you and how you use Assistant, and you might not want Google to keep that. You do not need to have Google purge your data, but you can set it up to delete every 3, 18, or 36 months. Specifically, you can purge web and app activity and your audio recordings. We'll show you how!

Once that's done, you can set up auto-delete in the same way for Audio recordings. It's not a bad idea to purge data from Google occasionally. Google uses this data to try and make services (and ads) more personalized, but data from 18 or 36 months ago is probably not terribly relevant to what you want to do today.
