Sugar Market Web Tracking Field 'ip_privacy'

Hello,

I was recently reviewing the web tracking code for Sugar Market and noticed that one of the first fields is 'ip_privacy', specifically in the case of our web tracking script this line shows "ip_privacy: 0,"

Does anyone know what this field is? The name makes me think it may be leveraged to keep the page visitor's ip private, which is an option our exec team would love to have.

Cheers,
Ed
