Last time I read it, it wasn't actually all that long. It was just full of qualified language like "in some circumstances such and such could be collected" and "Some Google services may do this". At the end of it, it was entirely unclear to me what Google actually did collect, but "services may do this" is really no different from "services can do this" and the result was essentially little more than "we can collect every bit of information you send to us, which we may or may not do". The qualified language was engineered very carefully to make it sound not like that.
