That said, in the course of providing service, we sometimes need to pass some of your data to one of our vendors (so we can bill your credit card, for example); so we do reserve the right to do things like that.
But under no circumstances will we sell any of your data to anyone.
To help us improve Lumen, we may analyze your data.
We have to know who you are, so we do put cookies on your computer (the cookie is what tells us "hey, this is the guy who logged in 5 minutes ago, so don't make him log in again!"). However, cookies will never be used for third-party tracking/revenue generating purposes.
