It’s pretty simple. The two main components are that we use Google Analytics to collect data, and we collect IP and device info for certain actions. All of these are “non-identifying” – we don’t have user accounts, so we don’t know who you are. We just know that there are people who do certain things on the site (like remove machines from locations) and they do so using x browser/app on y device.
Regarding Google Analytics, honestly we’re not very diligent with viewing it. And we don’t do anything with that data (no advertising) aside from getting a read on how many visitors hit the site and what browser they’re using. If we learn that GA is slowing down performance, we’d probably scrap it and life would continue.
