The question is not about whether your wife can employ a forensic computer analyst to look at your computer and find out if you've been just looking at AW pages or are logged in to AW as a member.
The question is, whether once you have created some special/unique AW email name/account, just for use on AW, the hackers can hack one day hack AW, find
the link back to your MAIN email account, and start sending you blackmail ransom demands.
Once a hacker has your main email address, on the darkweb they can buy the rest of your personal details for about £25, including your address.
The fewer places you are registered on, the better.
BTW. On another note. Remember that clicking on "remove browsing history".....still leaves the last address that you pasted and visited - in the address bar. This means that if your children/wife open your computer, put the curser in the address bar, and click PASTE, the last site you visited will STILL appear in the address bar.
The last action should be to paste something like "YouTube" in your address bar and click enter.
