We also use this information to understand how people use our <a href="/web/20120904221350/https://www.facebook.com/about/privacy/your-info-on-other#platform">Platform</a>.</td></tr><tr><td style="background: #f5f5f5;">Security and site integrity</td><td>We use these to help keep Facebook safe and secure. They support or enable security features and help us detect activity that violates our <a href="/web/20120904221350/https://www.facebook.com/legal/terms">Statement of Rights and Responsibilities</a>. <br/><br/> For example, they help protect your account from being accessed by anyone other than you. Cookies also let us know when several people have logged in from the same computer. </td></tr><tr><td style="background: #f5f5f5;">Advertising</td><td>Things like cookies and pixels are used to understand and deliver ads and make them more relevant to you. <br/><br/> For example, we may read a cookie that tells us you’re logged into Facebook so we can show you ads that may be interesting to you on Facebook or other websites. We may also use a cookie to learn whether someone who saw an ad on Facebook later visited the advertiser’s site. Similarly, one of our partners may use a cookie to determine whether we’ve shown an ad and how it performed. We also may work with a partner to show you an ad on Facebook after you’ve visited the partner’s site and this may involve the use of cookies.</td></tr><tr><td style="background: #f5f5f5;">Localization</td><td>These help Facebook provide a localized experience. <br/><br/> For example, we may store information in a cookie that is placed on your browser or device so you will see the site in your preferred language.</td></tr><tr><td style="background: #f5f5f5;">Site features and services</td><td>These provide functionality that help us deliver products and services. <br/><br/> For example, cookies help you log in by pre-filling the username field and help make chat a better experience by showing which of your friends are online. We may also use cookies to help us provide you with social plugins and other customized content and experiences.</td></tr><tr><td style="background: #f5f5f5;">Performance</td><td>We use these to provide you with the best experience possible. <br/><br/> For example, we may use a cookie to help us route traffic between servers and understand how quickly Facebook loads for different users. Sometimes we may store information on your browser or device so Facebook features you are using load and respond faster.</td></tr><tr><td style="background: #f5f5f5;">Analytics and research</td><td>These are used to understand, improve, and research products and services. <br/><br/> For example, we may use cookies to understand how you are using social plugins to improve them.

The resulting connection can include information such as the person’s IP address, the time the person viewed the pixel and the type of browser being used. <br/><br/> We use pixel tags to customize your experience and learn about how people use products and services. For example, we can use pixel tags to see that a person using a certain browser saw an ad on Facebook and also bought a product from that advertiser. This helps us show advertisers that the ads they run on Facebook are effective. </div><div class="UIFaq_Sharing"><div class="fsm fwn fcg"><a href="/web/20120904221350/https://www.facebook.com/help/?faq=236257763148568#What-are-pixel-tags?-How-does-Facebook-use-them?">Permalink</a> · <a href="/web/20120904221350/https://www.facebook.com/ajax/sharer/?s=34&p[]=236257763148568" rel="dialog">Share</a></div></div><div class="pam feedbackBox uiBoxGray"><form rel="async" action="/web/20120904221350/https://www.facebook.com/support/ajax/feedback.php" method="post" onsubmit="return window.Event && Event.__inlineSubmit && Event.__inlineSubmit(this,event)" id="uk253h_35"><input type="hidden" name="lsd" value="AVrbaQD0" autocomplete="off"/><input type="hidden" name="id" value="236257763148568"/><input type="hidden" name="context" value=""/><div class="clearfix"><div class="lfloat">Was this answer helpful?</div><span class="feedbackButtons rfloat"><label class="uiButton" for="uk253h_22"><input value="Yes" type="submit" name="yes" id="uk253h_22"/></label><label class="uiButton" for="uk253h_23"><input value="No" type="submit" name="no" id="uk253h_23"/></label></span></div></form></div></div></div></div></div></li><li class="uiListItem uiListVerticalItemBorder"><div><div class="fb-faq-330525367015217 UIFaq_Container clearfix fb-faq-330525367015217 UIFaq_Container clearfix" id="fb-faq-330525367015217-616138241"><div class="UIFaq_Arrow"><span class="UIFaq_ClosedArrow"><a onclick="JSCC.get("j0KEjRKwTtbXmaAnNE9").toggleAndLog({"search_id":null,"faq_locale":"en_US","faq_id":330525367015217,"context":""}); return false;" href="#"><i class="img sp_7xb6dg sx_356eb5"></i></a></span><span class="UIFaq_OpenArrow"><a onclick="JSCC.get("j0KEjRKwTtbXmaAnNE9").toggleAndLog({"search_id":null,"faq_locale":"en_US","faq_id":330525367015217,"context":""}); return false;" href="#"><i class="img sp_443ui0 sx_f5e616"></i></a></span></div><div class="UIFaq_Content"><div class="UIFaq_Question"><a href="/web/20120904221350/https://www.facebook.com/help/?faq=330525367015217#What-is-local-storage?-How-does-Facebook-use-local-storage-technologies?" onclick="JSCC.get("j0KEjRKwTtbXmaAnNE9").toggleAndLog({"search_id":null,"faq_locale":"en_US","faq_id":330525367015217,"context":""}); return false;"><div>What is local storage?

Some examples include device or HTML5 local storage and caching. Most web browsers offer settings for you to control whether or not to allow local storage. <br/><br/> We use local storage to understand and improve how our products and services perform and to enable certain features. For example, we may store certain parts of the Facebook website on your device so that those pages load faster the next time you visit them. Local storage also allows us to provide certain services to someone who doesn’t have access to the internet. For example, you can read and compose messages in the Facebook Messenger app when you’re offline because we store those messages locally on your device. </div><div class="UIFaq_Sharing"><div
