Last updated:

Our website uses cookies to function properly, as well as to perform other ancillary functions. Here’s the full list for you to review.

This Cookie Policy explains how Zello uses cookies and similar technologies in connection with our Services.

If you have any questions or concerns about the Cookie Policy, please contact us at [email protected] or as otherwise described in our Privacy Policy.


We and our partners use cookies, device identifiers and other similar technologies to operate and administer our Services, making it easier for you to use the Sites during future visits, and gather usage data on our Services.

Cookies and other similar technologies can be stored on your computer or device for different periods of time. For example, some cookies expire after a certain amount of time, or upon logging out (session cookies), others survive after your browser is closed until a defined expiration date set in the cookie (as determined by the third party placing it) and help recognize your computer when you open your browser and browse the Internet again (persistent cookies). Our Sites uses cookies and similar technologies from the third parties described below. For more details on cookies please visit All About Cookies.

Pixel tags or “clear” gifs are small images on a web page or in an email. When you visit the Sites or view one of our emails, we will use pixel tags, from the third parties described below, to track your activity on our Sites (for example, to know when content has been shown to you) and to personalize your experience. We also use pixel tags to determine what types of email your browser supports.

The cookies placed through your use of our Site are either set by us (first-party cookies) or by a third party at our request (third-party cookies).

This Cookie Policy refers to all these technologies collectively as “cookies.”

More specifically, we use cookies for the following purposes:

Advertising Cookies

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 adverts 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.
