I've been having this weird issue where it seems like someone else can see the videos and websites I'm visiting on my devices. I'm on a family phone plan, and I initially thought this might be because my iCloud is linked to my phone number, which the plan owner has access to. I logged out of iCloud, but they still seem to see my activity. I even tried using another Apple device that isn't linked to my number or iCloud, and the same issue occurred. As a last resort, I tested an Android device, and they could still see what I was doing. The only common factor is that all devices were connected to the same Wi-Fi. Does anyone know what's going on and how I can fix this?

If you’re all using the same Apple ID, that might be why your activities are visible to others on the plan. Sometimes, sharing an account can lead to sharing history too. Double-check your Apple ID settings to ensure you're logged into separate accounts.
How are you certain someone is monitoring your activity? Can you share how you figured this out? Specific examples would help clarify.
It’s unlikely that someone can track your internet activity just because they are the contract owner. Being on the same Wi-Fi shouldn’t expose your browsing either, unless there are tracking certificates installed. To be safe, log out from all devices, change your passwords, and enable two-factor authentication.
Sounds to me like it might be a Google Account issue. If they're tracking your IP address, they could be seeing some of your activity that way. Just a thought!
If you share a Google account, that could definitely share your YouTube and browsing history. Make sure you’re using individual accounts on all devices. It helps in keeping your activities private.

That makes sense. I’ll try logging out and changing my passwords to see if that helps.
