What are third-party cookies and how does CZI use them?
Cookies are small text files sent by your computer or device each time you visit chanzuckerberg.com. They are stored in your browser and allow a website or a third party to recognize the browser on your device. Other technologies, including identifiers associated with your device, and other software, are used for similar purposes. We also use pixels: a type of technology placed on a website or within the body of an email for the purpose of tracking certain activity, such as views of a website or when an email is opened. Pixels are often used in combination with cookies.
“Third-party cookies” are a type of cookie placed by someone other than CZI. These cookies may be persistent and gather browsing activity across multiple websites and across multiple sessions. They are stored until you delete them, or until they expire after the time period set in that third-party cookie. The table below lists the third-party cookies and pixels we use.
You have control over the types of cookies you allow on chanzuckerberg.com. You can learn more and adjust your cookie preferences by visiting the Cookie Settings [link to Preference Center]. You also have choices and control over the cookies that you allow onto your browser generally. For example, your browser may offer settings that allow you to choose whether browser cookies are set and to delete them. For more information about these controls, visit your browser “help” resources. Below are the types of cookies we use on chanzuckerberg.com:
Type of Cookie
Purpose
Type of Cookie
Strictly Necessary
Purpose
Certain cookies are strictly necessary for the website to function and can’t be switched off. You can set your browser to block or alert you about these cookies, but some parts of the site won’t work as a result.
Type of Cookie
Functional
Purpose
These cookies are functional, but not strictly necessary; set by us (or by third parties whose services we have added to the site), they enable the website to provide enhanced functionality and personalization. You may disable some or all of that functionality if you do not allow these cookies.
Type of Cookie
Analytics
Purpose
Analytics cookies collect information that allows us to understand how often you use our website, where you are accessing the website from, and the links and content on our website that you interact with. We use these cookies to support our website and to improve its operation.
Type of Cookie
Marketing and Social Media
Purpose
We use certain cookies to inform our own marketing and digital content efforts, which help us tell people about the work we do. For example, if a Twitter or Facebook user visits the CZI website, Twitter and Facebook can then identify them as part of a group of CZI website visitors in order to serve them with marketing and digital content messages about CZI and our work. You can go to these websites via the links below to opt-out of these marketing and digital content messages. There are no third-party ads on the CZI website, so we don’t use any cookies to serve third-party ads.
Since the number and names of cookies and pixels may change, this table may be updated from time to time; when we update it, we will note material changes in this notice. The expiration dates for our cookies below generally apply on a rolling basis or from the last time a user has interacted with the CZI website.
