I'm learning a language, I speak it in public to other people who do. I don't research the language, because I have some old text books on it. My partner doesn't speak it and doesn't research it on their devices. I don't normally have my phone on me in public, but my partner does. It took about 4 months of publicly speaking in the language before they got ads
What do you think this means?
::edit::
It was a Reddit ad and my city has embraced those AI smart cameras, so I assume some of those are Google owned which makes sense with Reddit and Google's recent alliance. This is assuming our devices aren't listening to us without our permission and AI cameras are mining data on passersby
Other theories are that since cellphones are involved it doesn't matter if I nor my partner ever searched for the language, at some point my phone or partner's phone was near someone who spoke that language and the data brokers/ad sellers inferred from there
Seems like the consensus is that I must have posted in the language on some social media or used Google to research it or made some new friends who speak the language and that's why
The sources I know are in Russian so they won't be useful for you but generally gapps have this feature and idk if it can be fully disabled without degoogling.
I can translate Russian, I'd love to see their research
The first sources I've ever found was this https://piped.video/watch?v=gsZo_I8wIKI and this https://piped.video/watch?v=U0SOxb_Lfps
But since it's a very popular topic, you can find more articles, tests and researches. There's also this video that explains other kinds of tracking https://piped.video/watch?v=gsZo_I8wIKI
I'm bad at searching and I don't follow actual research papers. You can find that yourself I think.
Yeah I'm more on the actual research paper route, I need science and not opinion or speculation. But with that, I'll probably take a look since community lead efforts can be good too, thanks for sharing
