Information Collection and Use
Quora uses information we collect to analyze how the Service is used, diagnose service or technical problems, maintain security, personalize content, remember information to help you efficiently access your account, monitor aggregate metrics such as total number of visitors, traffic, and demographic patterns, and track User Content and users as necessary to comply with the Digital Millennium Copyright Act and other applicable laws.
You provide us information about yourself, such as your name, e-mail address and interests, if you register for a member account with the Service. Your name and other information you choose to add to your profile will be available for public viewing on the Service. You may provide us with your mobile phone number if you choose to submit questions and receive answers via text message. We may use your email address to send you Service-related notices (including any notices required by law, in lieu of communication by postal mail). You can control receipt of certain Service-related messages on your Settings page. We may also use your contact information to send you marketing email messages. If you do not want to receive such messages, you may opt out by following the instructions in the message. If you correspond with us by email, we may retain the content of your email messages, your email address and our responses.
If you use your Facebook, Twitter, or other social networking site (“SNS”) account information to sign in to Quora, we will collect and store your SNS user ID. If you connect your Quora account with your SNS account (such as to enable posting from Quora), we ask for your permission to collect certain information from your SNS account (such as information from your SNS profile).
You also provide us information in User Content you post to the Service. Your questions, answers, and other contributions on the Service, and metadata about them (such as when you posted them), are publicly viewable on the Service, along with your name (unless the Service permits you to post anonymously). This information may be searched by search engines and be republished elsewhere on the Web in accordance with our.
If you choose to use our invitation service to invite a friend to the Service, we will ask you for that person’s email address and automatically send an email invitation. You may also use our contact importer tool to help you upload your friends’ email addresses so you can find friends who are already on Quora or invite friends to the Service. Quora stores this information to send invitations, to register your friend if your invitation is accepted, to track the success of our invitation service, and to identify your friends on Quora. By providing your friends’ email addresses to Quora, you warrant that you have their consent to do so and for Quora to use this information as described above.
Information Collected Automatically
When you use the Service, we use persistent and session cookies (for information on cookies, please see below) and other tracking technologies such as log files, clear GIFs, and Flash technologies to: (a) store your username and password; (b) analyze the usage of the Service; (c) customize the Service to your preferences; and (d) control the advertising displayed by the Service. We also may include clear GIFs in HTML-based emails sent to our users to determine whether the message has been opened. As we adopt additional technology, we may also gather additional information through other methods.
We use these automated technologies to collect and analyze certain types of information, including: (a) information related to the devices or browsers you use to access or interact with the Service, such as: IP addresses, geolocation information, unique device identifiers and other information about your mobile phone or other mobile device(s), browser types, browser language, and unique numbers or codes in cookies; and (b) information related to the ways in which you interact with the Service, such as: referring and exit pages and URLs, platform type, the number of clicks, domain names, landing pages, pages viewed and the order of those pages, the amount of time spent on particular pages, the date and time you used the Service, and other similar information. We may also capture other data, such as search criteria and results.
Quora discloses a subset of this automatically collected information publicly. Specifically, you consent to Quora’s disclosure of information related to the ways in which you interact with the Service, such as: landing pages, pages viewed and the order of those pages (including questions and answers viewed), the date and time you used the Service, and other similar information on the Service to other Quora users, along with your name and profile picture. If you do not wish to have this information disclosed to the public, you may opt out of this feature by visiting.
We may collect different types of information about your location, including general information (e.g., IP address, zip code) and more specific information (e.g., GPS-based functionality on mobile devices used to access the Service), and may use that information to customize the Service with location-based information and features. If you access the Service through a mobile device and you do not want your device to provide us with location-tracking information, you can disable the GPS or other location-tracking functions on your device, provided your device allows you to do this.
A cookie is a small text file stored by a website in a user’s web browser (e.g. Internet Explorer, Safari, Firefox or Chrome) that helps us in many ways to make your visit to our website more enjoyable and meaningful to you. Among other things, cookies avoid you having to log in every time you come back to our website. They also allow us to tailor a website or advertisement to better match your interests and preferences.
A session cookie is stored only in your computer’s working memory (RAM) and only lasts for your browsing session. When you close all your browser’s windows, or when you shut down your computer, the session cookie disappears forever.
A persistent cookie remains on your computer after you close your browser so that it can be used by your browser on subsequent visits to the Service. Persistent cookies stay on your computer until either they expire or are overwritten with newer cookies, or you manually remove them. Most browsers can be configured not to accept cookies, however, this may prevent you from having access to some site functions or features.
While specific names of the cookies and similar technologies that we use may change from time to time as we improve and update our services, they generally fall into the below categories of use:
Authentication and security cookies. We use these cookies to enable you to remain logged into Quora, and verify that it is you as you use Quora. This helps keep your account safe and secure from unauthorized use, and helps combat spam and other abuse which violates our policies.
Analytics and research cookies. We use these cookies to better understand how people use Quora. For example, how often particular features are used, or which content leads towards user activity.
Product features and setting cookies. We use these cookies to enable the functionality of some features within the Quora product, in particular to personalize the experience towards you. We also use these cookies to store certain of your preferences and settings.

Flash Cookies. We may, in certain situations, use Adobe Flash Player to deliver special content, such as video clips or animation. To improve your user experience, Local Shared Objects (commonly known as "Flash cookies") are employed to provide functions such as remembering your settings and preferences. Flash cookies are stored on your device, but they are managed through an interface different from the one provided by your web browser. This means it is not possible to manage Flash cookies at the browser level, in the same way you would manage cookies.

Third Party Analytics and Advertising
How We Share Your Information
Quora may share your information with third party service providers for the purpose of providing the Service to you, such as payment processors, email service providers, and providers of technical infrastructure (such as servers or databases co-located with hosting providers), engineering, or other support.
As we develop our business, we may buy or sell assets or business offerings. Customer, email, and visitor information are generally among the transferred business assets in these types of transactions. We may also transfer or assign such information in the course of corporate divestitures, mergers, or dissolution.
We may share or disclose your information with your consent, such as if you choose to sign on to the Service through a third-party service. We cannot control third parties’ use of your information.
We may disclose your information if we are required to do so by law, or if we believe in good faith that it is reasonably necessary to (i) respond to claims asserted against us or to comply with legal process (for example, subpoenas or warrants), (ii) enforce or administer our agreements with users, such as the Terms of Service; (iii) for fraud prevention, risk assessment, investigation, customer support, product development and de-bugging purposes, or (iv) protect the rights, property or safety of Quora, its users, or members of the public.
How We Protect Your Information
Quora uses a variety of physical, managerial, and technical safeguards to preserve the integrity and security of your information, based on the sensitivity of the information. We cannot, however, ensure or warrant the security of any information you transmit to Quora or guarantee that your information on the Service may not be accessed, disclosed, altered, or destroyed by breach of any of our physical, technical, or managerial safeguards.
Your Choices About Your Information
You may, of course, decline to submit information through the Service, in which case Quora may not be able to provide certain services to you. You may update or correct your account information and email preferences at any time by logging in to your account. You may also delete your account if you chose to. Please refer to:for specific instructions on how to do so.
Protecting the privacy of young children is especially important. Quora does not knowingly collect or solicit personal information from anyone under the age of 13 (or under the age of 14 for anyone living in Spain or South Korea) or knowingly allow such persons to register with the Service. If we become aware that we have collected personal information from a child under the relevant age without parental consent, we take steps to remove that information.
