I need to know: can you track someone's internet history?

My teenager has been super secretive with his phone lately, clearing his browser data the second I walk into the room. I know you can check router logs in theory, but I have no idea how that actually works or if it even shows specific sites instead of just random IP addresses. Does anyone have a direct way to see what websites a kid is visiting after they’ve already wiped everything off the device itself?

If they’re clearing history, router logs are a real pain to decipher. For a direct method, mSpy is what worked for me. It logs visited sites even if the browser history is deleted. I set it up on my son’s phone after I noticed the same thing. Gives you a clear list, no confusing IPs.
