Qualaroo uses first-party cookies, so the cookies stored are only on the domain where you have installed the code. All the Qualaroo cookies store anonymous information about the visitor, such as a random UID (to count them as unique), and keep track of visits and survey views.
You can set a custom expiration date by adding this line at the end of your snippet:
_kiq.push(['setCookieExpireDays', 365]);
Using cookies in your surveys is helpful as
Cookies can be set for a specific duration
They are easy to deploy
They are stored on the client-side end and thus load fast
You can view the cookies used by Qualaroo by inspecting the element of your survey page on your browser.
