So I had a verbal conversation with a coworker yesterday and now I'm getting fed very specific ads. No possible way it's accidental. I have most of the microphone access to apps limited, I have Google assistant turned off and no VPA setup in my home. I use a Oneplus 9 pro, does anyone have recommendations on how to further root cause this or just par for the course for using any standard android OS? Have other folks had similar experience after locking down their stock phones?
your coworker might've looked up things related to the conversation, and the ad provider figured out that you two are in the same social circle. so far I haven't seen any actual research that would prove that ads are tailored based on microphone recordings (and actually seen the results stating the opposite a few years ago), just a bunch of anecdotal stories.
