class="c01-rich-text-editor twtr-component-space--md twtr-rte"> <p>Our services use cookies and other similar technologies, such as pixels or local storage, to help provide you with a better, faster, and safer experience. Here are some of the ways that our services, including our various websites, SMS, APIs, email notifications, applications, buttons, widgets, and ads, use these technologies: to log you into Twitter and Periscope, save your preferences, personalize the content you see, protect against spam and abuse, and show you more relevant ads.<br/> </p> <p>Below we explain how Twitter, our partners, and other third parties use these technologies, your privacy settings, and the other options you have.</p> <h3>What are cookies, pixels, and local storage?</h3> <p>Cookies are small files that websites place on your computer as you browse the web. Like many websites, Twitter, Periscope, and our other services use cookies to discover how people are using our services and to make them work better.</p> <p>A pixel is a small amount of code on a web page or in an email notification. As many services do, we use pixels to learn whether you’ve interacted with certain web or email content. This helps us measure and improve our services and personalize your experience.</p> <p>Local storage is an industry-standard technology that allows a website or application to store information locally on your computer or mobile device. We use local storage to customize what we show you based on your past interactions with our services.</p> <h3>Why do our services use these technologies?<br/> </h3> <p>Our services use these technologies to deliver, measure, and improve our services in various ways. These uses generally fall into one of the following categories:<br/> </p> <ul><li><b>Authentication and security:</b><ul><li>To log you into Twitter and Periscope.<br/> </li><li>To protect your security.</li><li>To let you to view content with limited distribution.</li><li>To help us detect and fight spam, abuse, and other activities that violate the <a href="/web/20210508171215/https://help.twitter.com/en/rules-and-policies/twitter-rules" rel="nofollow">Twitter Rules</a> and the <a href="https://web.archive.org/web/20210508171215/https://www.periscope.tv/content" target="_blank" rel="nofollow noopener noreferrer">Periscope Community Guidelines</a>.</li><li>For example, these technologies help authenticate your access to Twitter and Periscope and prevent unauthorized parties from accessing your account. They also let us show you appropriate content through our services.</li></ul> </li><li><b>Preferences:</b><ul><li>To remember information about your browser and your preferences.</li><li>For example, cookies help us remember your preferred language or the country that you are in. We can then provide you with Twitter and Periscope content in your preferred language without having to ask you each time you visit Twitter or Periscope. On Twitter, we can also customize content based on your country, such as showing you what topics are trending near you, or to withhold certain content based on applicable local laws.

We might also optimize and improve your experience on Twitter and Periscope by using cookies to see how you interact with our services, such as when and how often you use them and what links you click on. We may use Google Analytics to assist us with this. <a href="https://web.archive.org/web/20210508171215/https://developers.google.com/analytics/devguides/collection/analyticsjs/cookie-usage" rel="nofollow">Learn more</a> about the cookies you may encounter through our use of Google Analytics. We might also use cookies to count the number of users that have seen a particular embedded Tweet or timeline. <a href="https://web.archive.org/web/20210508171215/https://dev.twitter.com/web/overview/privacy" rel="nofollow">Learn more</a> about the analytics cookies used by Twitter for Websites widgets.</li></ul> </li><li><b>Personalized content:</b><br/> <ul><li>To customize our services with more relevant content, like tailored trends, stories, ads, and suggestions for people to follow.</li><li>For example, local storage tells us which parts of your Twitter timeline or Periscope Global Feed you have viewed already so that we can show you the appropriate new content. Cookies can help us make smarter and more relevant suggestions about who you might enjoy following based on your visits to websites that have integrated Twitter embeds, including embedded timelines.</li></ul> </li><li><b>Advertising:</b><br/> <ul><li>To help us deliver ads, measure their performance, and make them more relevant to you based on criteria like your activity on Twitter and visits to our ad partners' websites.</li><li>For example, we use cookies and pixels to personalize ads and measure their performance. Using these technologies, we can show you ads and evaluate their effectiveness based on your visits to our ad partners' websites. This helps advertisers provide high-quality ads and content that might be more interesting to you.</li><li>We also work with third-party advertising partners, including Google, to market our services and serve ads on behalf of our advertisers, including through the delivery of interest-based ads.<br/> </li></ul> </li><li><b>Personalization across devices:</b><ul><li>By better understanding how devices are related, we can use information from one device to help personalize the Twitter experience on another device.</li><li>When you log in to Twitter on a device, we associate that device with your Twitter account. Whether or not you are logged in to Twitter, we may also receive information about your devices when, for example, that information is shared by a partner; you visit Twitter.com; you visit third-party websites that integrate Twitter content; or you visit a Twitter advertiser’s website or mobile application. We may use this information, most commonly IP addresses and the time at which the information was received, to infer that certain devices are associated with one another, including the devices on which you log in to Twitter.
