This can be parsed two different ways, though:

We will not scan your messages. (One possible reason we would have done this would be for advertising.)

vs.

We will not use the scans we perform on your messages to make advertising decisions.

I'm honestly not sure which it is (although I also don't care much personally since I don't use Gmail).
