What is a Tracking technology?
A tracking technology is a mechanism allowing the website to monitor and measure user behavior and interest for multiple purposes. Some are necessary for internet operation and functioning, performance measures, load balancing, or maintenance; some others provide services to the user for context and behavior-based customization, some may also be used for marketing purposes and profiling.
There are different types of online tracking technologies used on the internet as summarized below. The most common online tracking technology used today is called “Cookies”. This policy is intended to apply broadly to all types of online tracking technologies, including Cookies. All rules and practices listed in this document apply in similar ways for these other technologies even if the term “cookies” is used.
A cookie is a small data file, typically a text file of letters and numbers, that is placed by either our web sites (these are called “first party cookies”) or by other web sites that provide the content or features on the web page that you are viewing (these are called “third party cookies”). Cookies are sent by the web servers for our web sites, or by the web servers for the third party content provided on our sites and are stored on your device. Your device can be, but not limited to a personal computer, mobile device, personal assistant, or an Internet-connected smart TV.
Cookies enable the web site that set the cookie to store small bits of information on your device and retrieve that information at a later time. Unlike flash cookies, which we describe below, each cookie is unique to the web browser you are using on your device, so if you visit our web sites from multiple devices or multiple web browsers, our web sites will set separate cookies on each device and browser.
Other technologies that perform functions like cookies include:
- Single-pixel tags, which also are known as web beacons, web tags and clear GIFs, are graphics that function like cookies. The tags are not visible when viewing a web page or email because of their small size. They work by sending information along with the request to the web server with image.
- ETags are unique values used for web page caching that allow a web site visitor to be recognized in subsequent visits.
- Scripts are code that is embedded into some of our web pages that provides certain information about your web browser to the code provider when you visit those web pages.
- Flash cookies, also known as a local shared object, are used by the Adobe Flash Player and can contain not only the type of information stored in other cookies, but also information specific to Adobe Flash Player, such as where a video stopped playing on your device. Flash cookies are also capable of storing more information than other cookies. Flash cookies are different from other cookies in that they can share information among different web browsers on your device. We only use Flash Cookies to enhance the user experience when we deliver rich content such as video clips. Users who wish to disable these types of cookies can do so as described below.
- We do not use Fingerprinting technologies.
When you use a mobile application or device, we use data collection tools to collect information about your use of and interaction with the mobile application, such as operating system type, browser type, domain and other system settings, search queries, the time zone in which the mobile device or tablet is located, mobile phone service provider, metadata and other information associated with other files stored on your device. We may also collect information about the location of the mobile device or tablet used to access the mobile application (“Location Data”).
- Location Data includes: (i) the location of the mobile device or tablet derived from GPS or WiFi use; (ii) the IP address of the mobile device or tablet or internet service used to access the Services; and (iii) other information made available by a user or others that indicates the current or prior location of the user, such as geotag information in photographs. We will inform you if a specific mobile application collects precise Location Data.
- Advertising IDs, like Apple IDFA (Identifier for Advertisers) or GAID (Google Advertising ID) are unique, user-resettable IDs for advertising. They are a random device identifier assigned by Apple or Google to a user’s device, not us. Those identifiers can be used by mobile applications to evaluate quality of marketing campaigns.
As explained above, tracking technologies, like cookies, are used for multiple purposes ranging from strictly necessary ones used for web site operation to others which help us improve your experience and customize content provided to you. Cookies may serve many functions. They can help remember your username and preferences, analyze how well our web sites are performing, and enable us to recommend content that we believe may be most relevant to you. Most cookies identify your device’s web browser rather than identifying you personally, however, as described further below, certain cookies can be linked to other personal information we collect from or about you.
We use both session cookies, which are temporary cookies that are erased from your device’s memory when you close your Internet browser or turn off your device, and persistent cookies, which are stored on your device until they expire, unless you delete them before that time.
Session cookies enable our web sites to remember your web site preferences during the duration of your visit until you close your web browser, For example whether you have identified yourself as a health care professional or a resident of a particular country.
What categories of cookies do we use and what are your options to control them?
We have grouped the cookies our web sites use into five categories to help you understand the purposes for which they are used and the options you have to control them. We describe these tracking categories and your available choices to control them below. In most countries, users to our web sites can indicate their consent to the use of configurable cookies by using the cookie preference tool where they can elect to “Accept All” or “Customize” their choices. Where used, these tools will display prominently on a user’s first visit, whenever the cookie cache is cleared, or anytime via a prominent Cookie Panel button. By using these tools, a user can easily set and manage their cookie preferences.
In countries where the cookie preference tool has not been deployed, end users may elect to block cookies in their browser settings. Most web browsers enable users to manage preferences for cookies. If you set your browser not to accept cookies, you may not be able to use some sections of our web sites that depend on Strictly Necessary and Functional cookies.
Our Cookie Categories
How These Cookies Are Used
(may also be referred to as “Required”)
These cookies are necessary for the website to function and cannot be switched off in our systems. They are usually only set in response to actions made by you which amount to a request for services, such as setting your privacy preferences, logging in or filling in forms. You can set your browser to block or alert you about these cookies, but some parts of the site will not then work. These cookies do not store any personally identifiable information.
Since these cookies are strictly necessary for certain of our web sites to operate and function, our cookie preferences tools do not enable you to control these cookies. If you set your browser not to accept them, you will not be able to use the sections of our web sites that depend on them.
(may also be referred to as “Site Experience”)
These cookies enable the website to provide enhanced functionality and personalization. They may be set by us or by third party providers whose services we have added to our pages. If you do not allow these cookies, then some or all these services may not function properly.
Like Strictly Necessary cookies, our sites depend on Functional cookies to deliver content and features that you request when using our web sites. You can control the use of these cookies either by electing not to designate certain preferences offered on our web sites, or by controlling these cookies through your browser settings as described above. Third party cookies could be used for authentication or server balancing capabilities, but not for marketing purposes. If you set your browser not to accept these cookies, certain functionality on our web sites may not work.
(may also be referred to as “Operational”)
These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. They help us to know which pages are the most and least popular and see how visitors move around the site. All information collected by these cookies is aggregated and therefore anonymous. If users do not allow these cookies we will not know when users have visited our site and will not be able to monitor its performance.
(may also be referred to as “Advertising”)
These cookies may be set through our site by our advertising partners. They may be used by those companies to build a profile of your interests and show you relevant advertising on other sites. They do not store directly personal information but are based on uniquely identifying your browser and internet device. If you do not allow these cookies, you will experience less targeted advertising.
These cookies are set by a range of social media services that we have added to the site to enable you to share our content with your friends and networks. They can track your browser across other sites and building a profile of your interests. This may impact the content, suggestions, and messages you see on other websites you visit. If you do not allow these cookies, you may not be able to use or see these sharing tools.
Are there other ways to control third party cookies and other tracking technologies?
If you would like to opt-out of or limit the cookies set by other companies who deliver e-mail communications on our behalf or place our advertisements on other web sites, you may do so by following the options provided by:
- Network Advertising Initiative at: https://optout.networkadvertising.org/
- European Interactive Digital Advertising Alliance at: http://youronlinechoices.eu (if you are located in the EU)
- Digital Advertising Alliance (DAA)’s self-regulatory opt-out page at: https://optout.aboutads.info/ and mobile application-based “AppChoices” download page at: https://youradchoices.com/appchoices
- Some browser add-ons may also provide tracking technologies management functionalities. Consult your browser extensions to know which ones are available for your browser and how to install them.
- The Apple IDFA default setting is opt-out. Applications that want to access this ID will ask you to opt-in. IDFA can be reset manually.
- For GAID, opt-out within Google Play apps.
For mobile devices, users typically configure their tracking preferences either during initial set up of individual applications or within the application themselves post installation. If you do not want us to collect Location Data from your mobile device, please delete the mobile application or disable the location settings on your device or tablet. Note, disabling the location setting may affect your ability to access and use that mobile application.
Some internet browsers have incorporated “Do Not Track” features. Most of these features, when turned on, send a signal or preference to the web sites you visit indicating that you do not wish to be tracked (“DNT-signal”). As reflected throughout this Policy, we are committed to providing you with meaningful choices about the information collected on our website for third party purposes, and that is why we provide the variety of opt-out mechanisms described in our cookie panel, where deployed. In addition, where we deploy a cookie panel, it is designed to identify a browser-initiated DNT-signal and apply it to the cookie settings per your preferences. However, despite our best efforts, this may not function for all browsers. Using the cookie banner settings will ensure that your preferences are appropriately reflected.
Despite the protections described above, whether we deploy a cookie panel or not in your market, we do not currently recognize or respond directly to browser initiated DNT signals.
How will I know whether this Global Online Tracking Policy has been updated?
