Effective Date:

Last Revised: September 9, 2022

This Cookie Policy describes the cookies that Ethena, Inc. (collectively, “Ethena”, “we,” “our,” or “us”), and trusted third parties, use when you visit Ethena’s websites. In the spirit of transparency, this Cookie Policy provides detailed information about the types of cookies we use, why we use them, and your choices with respect to our use of cookies.

This Cookie Policy is part of and incorporated into our Privacy Policy. Ethena will treat any identifying information collected through our use of cookies in accordance with our Privacy Policy. Please refer to our Privacy Policy for more information and to learn more about our privacy practices.

What is a cookie?

Cookies are small data files that are sent to or accessed from your web browser or your computer’s hard drive by the websites you visit. A cookie typically contains the name of the domain (internet location) from which the cookie originated, the “lifetime” of the cookie (i.e., when it expires), and a randomly generated unique number or similar identifier. A cookie also may contain information about your computer, such as user settings, browsing history, and internet activities. If you make multiple visits to our site, cookies allow our website to recognize your browser. Generally, cookies may be categorized as:

  • First-party cookies. These are sent to a user’s device from a platform or domain managed by the entity who operates the website a user visits. 
  • Third-party cookies. These are sent to a user’s device from a platform or domain operated by an entity who does not operate the website a user visits. 

How do we use cookies?

We use cookies for a number of reasons, such as helping us keep our services and site secure, measuring the performance of our site, and counting the numbers of visitors. The cookies we use generally fall into one or more of the following categories:

  • Strictly necessary cookies. These cookies are strictly necessary to provide you with services available through our website and cannot be turned off. These cookies allow you to use some of the website’s features, such as granting access to areas that require registration and setting your privacy preference. 
  • Functionality cookies. These cookies allow you to browse our website or benefit from some of its enhanced features, such as memorizing language preferences. Similar to strictly necessary cookies, if these cookies are disabled, it may impact your experience to use our website and make your experience less personalized.
  • Performance cookies. These cookies are used to collect information to count visits and traffic sources so we can measure and improve the performance of our website. All information collected by performance cookies is aggregated and therefore anonymous. 
  • Social media cookies. These cookies are used when information is shared through a social media sharing button or “like button” on our websites or when you link your account or engage with our content on or through a social networking site such as Facebook, Twitter, or LinkedIn. 

How long are cookies stored on your device?

The duration of storage of cookies on your device may vary, depending on whether the cookies are temporary or permanent.

  • Temporary cookies. We use temporary cookies on all our secure pages to assign and register a session ID. A temporary cookie does not identify you by name, and it does not leave any information recoverable on your hard drive. Temporary cookies expire when you close your internet browser. 
  • Permanent cookies. Certain cookies are considered “permanent cookies” and stay on your computer for 24 hours, a week, or several years depending on the cookies’ function. This means that these cookies survive after your browser is closed and can be used by our website to recognize your device when you reopen your browser later.

Your Choices

At any time, you may control our use of cookies while you use our services, and you may disable cookies by changing the settings on your browser, phone and/or devices. Most browsers are set to accept cookies by default, but you can control and manage settings to remove or reject browser cookies manually within your brower’s configuration settings. To manage these settings, please follow the instructions given by your browser.

You can limit how cookies interact with your device or browser by enabling ad tracking functionality on both android and iOS devices. If you use a device to access our website, your device identification may be collected and used for purposes similar to other cookies. Please be aware, if you disable certain cookies, some of the features of our services may not function properly or be available to you, such as those which require identification.

We may update or change the cookies (or similar technologies) we use from time to time. The most up-to-date version of this Policy will be posted on our website at, and if we make any changes, we will update the effective date at the top of the Policy.
