Returned to Hulu and found you were already logged in? Have you ever noticed how the stories your favourite new site recommends change as you click on different links? Of course \u2014 those sites, like most websites, use cookies to \u201cremember\u201d you.<\/p>\n<p>Such conveniences make life online a touch nicer and more human-feeling. They also help marketers track your online activity and enable advertisers to target you with astonishing precision.<\/p>\n<p>So: Cookies make life a little bit nicer, but they\u2019re not exactly good for you. And although the term <em>Web cookie<\/em> <a href=\"https:\/\/en.wikipedia.org\/wiki\/HTTP_cookie%2523Origin_of_the_name\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">didn\u2019t directly derive<\/a> from the delicious pastries, the analogy holds on any number of levels.<\/p>\n<h2>Finding a balance<\/h2>\n<p>How can you manage Web cookies for the best mix of convenience and privacy? Start with the simplest distinction: first-party versus third-party cookies. Essentially, a first-party cookie doesn\u2019t venture beyond its own site \u2014 when you navigate away from the site, the cookie doesn\u2019t follow you. And a first-party cookie is sufficient to remember your site preferences and keep you permanently logged in, in most cases.<\/p>\n<p>Third-party cookies are not limited in that way. A third party might be an advertiser, for example, that places ads on several sites you visit. It knows you were at Amazon.com shopping for, let\u2019s say a new laptop. Then, when you go to another website that advertiser serves, say a newspaper\u2019s site, you\u2019ll see an ad for the very laptop you were just looking at on Amazon. Or you\u2019ll see what your spouse last shopped for at Amazon. Or your spouse will knock you off your computer to check Facebook and see an ad for what you were just shopping for, right before his birthday.<\/p>\n<p>OK, those are some mildly annoying aspects of third-party cookies \u2014 but let\u2019s not forget that the information doesn\u2019t simply go away but accumulates to form a comprehensive picture of you to entities that profit from it and have no responsibility to look out for your well-being.<\/p>\n<p>Another useful distinction is <em>session<\/em> versus <em>persistent<\/em> cookies. Session cookies keep track of the user when, for example, they navigate around a website. Set a site to display in English and as you click around, other pages on the site will also appear in English. Come back tomorrow and you may have to set that preference again. When you close your browser, session cookies are deleted.<\/p>\n<p>Persistent cookies live on your computer, and they stay there until they expire or you delete them.<\/p>\n<p>There\u2019s a lot more to cookies, but the most important thing you need to know is how to control them. You can manage cookies from within your browser\u2019s settings. In this case, controlling means deleting. You can delete Web cookies manually from time to time, through your browser\u2019s History interface, or set your browser to manage cookies automatically.
