I had an engineer about my router to sort out my issue and he noticed that I gamed a lot during the past few days. (I rarely do but got a cool game so I did a bit lately). I just wonder how? Well I did download a game last night and last month. I am wondering, did he see just my download history (which is fine) or my internet history? I hope he didn’t as it’s just embarrassing :( I went on dating sites before I found a girlfriend and I’d rather him not see that also on top of that I brought my GF a sort of erotic lingerie. I’m so embarrassed. Is it possible for engineer to see what I search?
They can definitely see where traffic goes. If you are not using their DNS however, and you are using DoH they don’t see which URL you are using, but they do see the IP traffic for very obvious reasons.
If the site is using TLS, they can’t see the URL, only the domain name. Get your “fun stuff” from a general purpose site like reddit or pinterest and your internet provider won’t know.
