Hi,
In the front-end, HikaShop can use a cookie to store the information about the "add to cart" popup.
That cookie will be removed from HikaShop in a future release but for the current versions (and if you have the setting to display "add to cart popup"), the cookie can be stored.
Otherwise, HikaShop use the Joomla session ; which use a cookie.
