What is Privacy Preserving Ad Measurement?

As a programmer who basically just works with logical assertments all day, I agree that the setting is very vague. I would guess, from the description, that the setting only acts on the privacy-preserving aspect of the action, ie. enable it to be anonymized, disable it to be identifiable, but you're gonna get ads either way. However, from the context of the settings page I could guess that I can uncheck if I don't want to be tracked at all, but that's a big IF and a risk I don't want to take. I rather be tracked and anonymous than risk being tracked and identified. Like you said, the question marks just reiterates the same sentence without clearing it up at all. It's a checkbox that may or may not do one or two things, and I don't know if I should leave it checked or blank. So yeah, this def could be worded alot better, and could use some clearing up.

Hi Ataraxy01,

As I understand it, if you uncheck the option there is no measures or tracking at all.

Clicked on, you are allowing privacy-preserving measures, while clicked off allows no measures at all.

With the setting either on or off, your objective "I do not want advertisers to know me or track me!" is being met. The measure is the effectiveness of the ad itself. I presume whether it was clicked, or not. What the privacy-preserving measure is doing is not letting that click be related to you, track you, etc.

"Exactly but, it is so unclear!" - Not saying that the wording is perfect in all circumstances, but this particular example seems clear enough, to me. Off = No ad effectiveness measures as all. On = Measures allowed, but with privacy protection.
