Cookie Notice

Effective as of November 1, 2023.

This Cookie Notice explains how Walrus and our corporate subsidiaries and affiliates (collectively, “Walrus”, “we”, “us” or “our”) uses cookies and similar technologies in connection with and, or the DoubleCheck ™ Service (collectively, the “Services”) and any other website that we own or control and which posts or links to this Cookie Notice.

What are cookies?

Cookies are small data files that are placed on your computer or mobile device when you visit a website.  Cookies serve different purposes, such as helping us understand how a site is being used, letting you navigate between pages efficiently, remembering your preferences and generally improving your browsing experience.  

We use two broad categories of cookies: (1) first-party cookies, served directly by us to your computer or mobile device, which we use to recognize your computer or mobile device when it revisits our Services; and (2) third-party cookies, which are served by service providers or business partners on our Services, and can be used by these parties to recognize your computer or mobile device when it visits other websites. Third-party cookies can be used for a variety of purposes, including site analytics, advertising, and social media features.

What types of cookies and similar technologies does Walrus use on the Services?

On the Services, we use cookies and similar technologies in the following categories described in the table below. 

Strictly necessary cookies

These cookies are necessary for the technical operation of our Services. For example, they enable you to stay logged in or to move around on a website and to use its features. Without these cookies, our Services cannot properly function.

Other technologies

In addition to cookies, our Services may use other technologies, such as pixel tags, to collect information automatically.

Browser Web Storage

We may use browser web storage (including via HTML5), also known as locally stored objects (“LSOs”), for similar purposes as cookies. Browser web storage enables the storage of a larger amount of data than cookies. Your web browser may provide functionality to clear your browser web storage.

Web Beacons

We may also use web beacons (which are also known as pixel tags and clear GIFs) in our Services and in our HTML-formatted emails to track the actions of users on our Services and interactions with our emails. Unlike cookies, which are stored on the hard drive of your computer or mobile device by a website, pixel tags are embedded invisibly on webpages or within HTML formatted emails. Pixel tags are used to demonstrate that a webpage was accessed or that certain content was viewed, typically to measure the success of our marketing campaigns or engagement with our emails and to compile statistics about usage of the Services, so that we can manage our content more effectively.

Your choices

In addition to rights you may have under laws that apply to you, you may take technological steps to affect your interactions with cookies and related technologies.

Most browsers let you remove or reject cookies.  To do this, follow the instructions in your browser settings.  Many browsers accept cookies by default until you change your settings.  Please note that if you set your browser to disable some or all cookies, the Services may not work properly and certain functionality may not be available to you.  

For more information about how we collect, use, and disclose your information on our marketing website, see our Website Privacy Policy.


We may update this Notice from time to time, so please check back on a regular basis for any changes.
