Twitter instantly connects people everywhere to what’s most meaningful to them. Any registered user can send a Tweet, which is a message of 140 characters or less that is public by default and can include other content like photos, videos, and links to other websites.
Tip What you say on Twitter may be viewed all around the world instantly.
Tip We collect and use your information below to provide our Services and to measure and improve them over time.
Information Collected Upon Registration: When you create or reconfigure a Twitter account, you provide some personal information, such as your name, username, password, and email address. Some of this information, for example, your name and username, is listed publicly on our Services, including on your profile page and in search results. Some Services, such as search, public user profiles and viewing lists, do not require registration.
Additional Information: You may provide us with profile information to make public, such as a short biography, your location, your website, or a picture. You may provide information to customize your account, such as a cell phone number for the delivery of SMS messages. We may use your contact information to send you information about our Services or to market to you. You may use your account settings to unsubscribe from notifications from Twitter. You may also unsubscribe by following the instructions contained within the notification or the instructions on our website. We may use your contact information to help others find your Twitter account, including through third-party services and client applications. Your account settings control whether others can find you by your email address or cell phone number. You may choose to upload your address book so that we can help you find Twitter users you know. We may later suggest people to follow on Twitter based on your imported address book contacts, which you can delete from Twitter at any time. If you email us, we may keep your message, email address and contact information to respond to your request. If you connect your Twitter account to your account on another service in order to cross-post between Twitter and that service, the other service may send us your registration or profile information on that service and other information that you authorize. This information enables cross-posting, helps us improve the Services, and is deleted from Twitter within a few weeks of your disconnecting from Twitter your account on the other service. Learn more here. Providing the additional information described in this section is entirely optional.
Tweets, Following, Lists and other Public Information: Our Services are primarily designed to help you share information with the world. Most of the information you provide us is information you are asking us to make public. This includes not only the messages you Tweet and the metadata provided with Tweets, such as when you Tweeted, but also the lists you create, the people you follow, the Tweets you mark as favorites or Retweet, and many other bits of information that result from your use of the Services. Our default is almost always to make the information you provide public for as long as you do not delete it from Twitter, but we generally give you settings to make the information more private if you want. Your public information is broadly and instantly disseminated. For instance, your public user profile information and public Tweets may be searchable by search engines and are immediately delivered via SMS and our APIs to a wide range of users and services, with one example being the United States Library of Congress, which archives Tweets for historical purposes. When you share information or content like photos, videos, and links via the Services, you should think carefully about what you are making public.
Location Information: You may choose to publish your location in your Tweets and in your Twitter profile. You may also tell us your location when you set your trend location on Twitter.com or enable your computer or mobile device to send us location information. You can set your Tweet location preferences in your account settings and learn more about this feature here. Learn how to set your mobile location preferences here. We may use and store information about your location to provide features of our Services, such as Tweeting with your location, and to improve and customize the Services, for example, with more relevant content like local trends, stories, ads, and suggestions for people to follow.
Links: Twitter may keep track of how you interact with links across our Services, including our email notifications, third-party services, and client applications, by redirecting clicks or through other means. We do this to help improve our Services, to provide more relevant advertising, and to be able to share aggregate click statistics such as how many times a particular link was clicked on.
Cookies: Like many websites, we use "cookie" technology to collect additional website usage data and to improve our Services, but we do not require cookies for many parts of our Services such as searching and looking at public user profiles or lists. A cookie is a small data file that is transferred to your computer's hard disk. Twitter may use both session cookies and persistent cookies to better understand how you interact with our Services, to monitor aggregate usage by our users and web traffic routing on our Services, and to customize and improve our Services. Most Internet browsers automatically accept cookies. You can instruct your browser, by changing its settings, to stop accepting cookies or to prompt you before accepting a cookie from the websites you visit. However, some Services may not function properly if you disable cookies.
Log Data: Our servers automatically record information ("Log Data") created by your use of the Services. Log Data may include information such as your IP address, browser type, operating system, the referring web page, pages visited, location, your mobile carrier, device and application IDs, search terms, and cookie information. We receive Log Data when you interact with our Services, for example, when you visit our websites, sign into our Services, interact with our email notifications, use your Twitter account to authenticate to a third-party website or application, or visit a third-party website that includes a Twitter button or widget. Twitter uses Log Data to provide our Services and to measure, customize, and improve them. If not already done earlier, for example, as provided below for Widget Data, we will either delete Log Data or remove any common account identifiers, such as your username, full IP address, or email address, after 18 months.
Third-Party Service Providers: Twitter uses a variety of third-party services to help provide our Services, such as hosting our various blogs and wikis, and to help us understand the use of our Services, such as Google Analytics. These third-party service providers may collect information sent by your browser as part of a web page request, such as cookies or your IP address.
TipWe do not disclose your private personal information except in the limited circumstances described here.
Your Consent: We may share or disclose your information at your direction, such as when you authorize a third-party web client or application to access your Twitter account.
Non-Private or Non-Personal Information: We may share or disclose your non-private, aggregated or otherwise non-personal information, such as your public user profile information, public Tweets, the people you follow or that follow you, or the number of users who clicked on a particular link (even if only one did).
If you are a registered user of our Services, we provide you with tools and account settings to access or modify the personal information you provided to us and associated with your account.
You can also permanently delete your Twitter account. If you follow the instructions here, your account will be deactivated and then deleted. When your account is deactivated, it is not viewable on Twitter.com. For up to 30 days after deactivation it is still possible to restore your account if it was accidentally or wrongfully deactivated. After 30 days, we begin the process of deleting your account from our systems, which can take up to a week.
Our Services are not directed to persons under 13. If you become aware that your child has provided us with personal information without your consent, please contact us at firstname.lastname@example.org. We do not knowingly collect personal information from children under 13. If we become aware that a child under 13 has provided us with personal information, we take steps to remove such information and terminate the child's account. You can find additional resources for parents and teens here.
