If you use the Google Chrome browser, then you probably know about the incognito window. This is a setting that allows you to browse the web without storing any cookies and without saving your history to the browser history. If your lover suddenly wants to use this all the time instead of normal windows – they might just be cheating.

Browser history is a web browser’s way of keeping track of what pages you’ve been to. The history is useful because you can search your history for a site you’ve seen but can’t remember the URL to. If you are cheating, you probably won’t want your partner to be able to browse all of the sites that you’ve been to. If you go to your lover’s computer and their browser history is always empty – they are probably hiding something.

Cookies are small bits of information that web pages leave on your computer. They can be used to track usage or even to store information that was entered in the past in case you return to a site. For example, if you log into a site, the site may put a cookie on your computer so that you can stay logged in and won’t need to sign in again. Unfortunately cookies can give away information about where you’ve been. Also, if you go to a site using a cookie, you may see someone’s login information already filled into a form. If your lover is always clearing their cookies – they may be trying to hide where they go online.
