So a few months ago, I got a half-broken old iPhone (microphone, speaker and cameras not working) for testing purposes and it lays 99.9% of the time on my shelf turned off. Today, I turned it on and after I opened Safari, I surprised in not exactly the most pleasant way.
When I started writing in the address bar a strange suggestion from Siri came up for a website my mom searched a few hours ago on her android tablet. Like what the actual fuck?? There is absolutely 0 connection between these 2 devices, there is PiHole running on local network. The only thing that I can think of is that she is using Google (logged out) and it looks like they are actively sharing their data based on IP addresses. Wow...
