I would read it more like the former, that "data we have collected" is similar to "information we have collected". Alternately, data is also often a synonym for "set of observations" or similar, a shorthand term for "data set", etymology notwithstanding. A common exchange: "Can you send us the fracking data?" "Sure, once I get approval I'll send it over." If you instead said "send them over" in this context it would suggest, at least in typical usage I'm familiar with, that there were not only multiple data points, but multiple data sets being set over.
