Ask HN: Google having access to Signal messages?
A troubling thing happened to my wife today. She got an ad based on a very rare word that only appeared on her phone in an inbound Signal message. She did not type it, did not say it out loud, and did not search for it. The chances of her getting a random ad on that specific word are low (the word is enneagram). How did Google get access to her inbound Signal messages?
