Does AddThis use socialite

Hello, I’d like to know if AddThis uses socialite, or some method to make the buttons load faster such as the “Floating Social Bar” wp plugin does…

If not, is this a plan, speed is really important these days.

If there is no option, is there a way I could still use your analytics without using your deployment of the social buttons etc?

Thank you
