What Are Cookies?
Cookies are small data files that are placed on your computer or mobile device when you visit a website. They are widely used by website owners to make their websites work, or to work more efficiently, as well as to provide reporting information. Cookies set by the website owner (in this case, PureVitals) are called "first-party cookies."
In addition to first-party cookies, some cookies are set by external services that provide functionality such as analytics or advertising. These are known as "third-party cookies" and are governed by the privacy and cookie policies of those respective providers.
Cookies are not software programs and cannot carry viruses or install harmful code on your device. They simply store a short string of text that your browser reads and sends back to the originating site on your next visit.
