What is a cookie?
A cookie is a small file placed onto your device that enables our site features and functionality. For example, cookies enable us to identify your device, secure your access to our site and our sites generally, and even help us know if someone attempts to access your account from a different device. Cookies also enable you to easily share content on our site and help us serve relevant ads to you.
When does our site place cookies?
What types of cookies does our site use?
We use two types: persistent cookies and session cookies. A persistent cookie helps us recognize you as an existing user, so it's easier to return to our site or interact with our services without signing in again. After you sign in, a persistent cookie stays in your browser and will be read by our site when you return to one of our sites or a partner site that uses our services (for example, our sharing or job application buttons). Session cookies only last for as long as the session (usually the current visit to a website or a browser session).
What are cookies used for?
Cookies can be used to recognize you when you visit our site, remember your preferences, and give you a personalized experience that's in line with your settings. Cookies also make your interactions with our site faster and more secure. Additionally, cookies allow us to bring you advertising both on and off the our site sites, and bring customized features to you through our site plugins such as our "Share" button.
If you're signed in to our site, cookies help us show you the right information and personalize your experience.
Preferences, features and services
Cookies can tell us which language you prefer and what your communications preferences are. They can help you fill out forms on our site more easily. They also provide you with features, insights, and customized content in conjunction with our plugins.
Performance, Analytics and Research
What is Do Not Track (DNT)?
DNT is a concept that has been promoted by regulatory agencies such as the U.S. Federal Trade Commission (FTC), for the Internet industry to develop and implement a mechanism for allowing Internet users to control the tracking of their online activities across websites by using browser settings. The World Wide Web Consortium (W3C) has been working with industry groups, Internet browsers, technology companies, and regulators to develop a DNT technology standard. While some progress has been made, it has been slow. No standard has been adopted to this date. As such, our site does not use "do not track" signals.
How are cookies used for advertising purposes?
Cookies and other ad technology such as beacons, pixels, and tags help us serve relevant ads to you more effectively. They also help us provide aggregated auditing, research, and reporting for advertisers, understand and improve our service, and know when content has been shown to you. Note: Because your web browser may request advertisements and beacons directly from ad network servers, these networks can view, edit, or set their own cookies, just as if you had requested a web page from their site.
If you are a our site member but logged out of your account on a browser, our site may still continue to log your interaction with our services on that browser for up to 30 days in order to generate usage analytics for our services, which analytics we may share in aggregate form with our advertising customers.
Unless you clear these cookies from your browser, we may use this information to:
provide more relevant, interest-based advertising
provide aggregate reports of ads activity to advertisers and websites hosting the ads
help website and app owners understand how visitors engage with their sites or apps
detect and defend against fraud and other risks to protect users and partners
improve our products
We do not provide any personal information that we collect to advertisers. You can opt-out of off-site and third-party-informed advertising by adjusting your settings. Please note that opting out will not remove advertising from the pages you visit; it will mean that the ads you see may not be matched to your interests. If you are not a our site member, learn more about cookies and how to opt out. Click here to learn more about the self-regulatory principles we adhere to.
What third-party cookies does our site use?
Our cookie table lists some of the third party cookies on our sites. Please note that the names of cookies, pixels and other technologies may change over time.
Most browsers allow you to control cookies through their settings preferences. However, if you limit the ability of websites to set cookies, you may worsen your overall user experience, since it will no longer be personalized to you. It may also stop you from saving customized settings like login information.
What to do if you don't want cookies to be set or want them to be removed?
