Is there a cookie to identify me when I'm vising my own website?

Hi y'all!

I am trying to identify and then exclude my internal traffic from my Google Analytics reports. I know Squarespace Analytics has a mechanism to identify internal website traffic, but I can't figure out what cookie or mechanism it is.
 

I imagine there should be some sort of flag when I am logged into Squarespace and on the production version of my website.

Any ideas on how to identify my internal traffic?
