As I understand it, reCAPTCHA only issues an actual puzzle to users it has reasons to doubt. In most cases, I only have to click a checkbox marked I am not a robot; and in a few rare cases, like if I'm in incognito mode, I have to click the parts of the image containing a car or something. Which clearly means that Google is fingerprinting me in order to guess whether I'm a human or not, and is storing information over time to facilitate the fingerprinting. It's not possible to get out of that. And ultimately, data that they have is data that they can use for ads; and we're supposed to "trust" them that they don't. Privacy policies are very nice and all, but they've been caught not respecting their own policies, haven't they? Though I guess whatever data they could get through reCAPTCHA would be rather insignificant compared to the firehose the vast majority of users sends to them anyway...
