What we use
Cookies keep you signed in and protect your session against forgery. The application does not work without them.
We also use cookies to understand how OpenStudio is used — which features people reach for, where something is slow, where a flow breaks down. What we learn there shapes what we build next. Some of this runs through third-party analytics providers, who process it on our behalf under contract; they are named on our trust portal with the rest of our subprocessors.
What we do not do
We do not sell what our cookies tell us, and we do not use them to advertise to you.
Managing cookies
Your browser settings control cookies, including ours. Turning off the essential ones will stop you signing in to OpenStudio.
Global Privacy Control
We honor Global Privacy Control signals as a valid opt-out.
