You don't have to be paranoid for that anymore, tech companies have been eavesdropping everyone for years now.
Once in a while I notice advertisements about the thing I talked about earlier, and that's not from entering a search phrase.On the other hand I'm fairly confident government here can't do it, most of their IT projects fail

I read some articles about the fact that most smartphones use
various methods and show us advertisements based on that, but I don't doubt that this is the case with all other
"smart" devices as well. Today's smart TVs are also real spy boxes, because every time they have a serious upgrade, you have to agree to a complete waiver of privacy and agree that all collected data is used by the manufacturer, but also by all those who will receive data from them. If you do not agree to the terms, you can no longer use the smart services of your TV.
