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?
Friend googles topic from his home wifi. You visit friend’s home for a couple of hours with your phone’s wifi enabled. Even without signing in to his wifi your phone still logs that you were in range of his wifi for 2 hours. Now you’ll get served ads for the topic that he googled about, because people who spend time together often have similar interests, or you may mention the advertised product to him if he ever talks to you about the topic.
