It seems these settings are default off for me, or if I switched them off myself it must have been quite a while ago that this feature was introduced and I forgot that I did so.
(About 'enhanced ad privacy' in chrome where it records ad subjects based on browsing history)
For anyone unaware, Google Chrome is currently rolling out an update that track your interests based on browsing history, then share them with 3rd party websites. The notification page makes it sound like they added a new privacy feature, but in actuality they automatically enrolled you into their tracking system and you have to go and manually opt out.
