The privacy implications of this are concerning. How long will these recordings be kept? Will the recordings, or excerpts from them, be sold to third parties?<p>I can see recorded conversations being used to extract data that is anonymized and then sold to third parties. An example: this week mentions of the company Foo,Inc. went up 35% in Mountain View,CA as opposed to up 5% average across the rest of the country. From this example it's reasonable that one of the companies in Mountain View is about to have a significant interaction with Foo, Inc., perhaps an acquisition, so this could be financially valuable information. And of course it would valuable to marketers.
