woocommerce_cart_hash;
woocommerce_items_in_cart;
wp_woocommerce_session_;
The first two cookies contain information about the cart as a whole and helps WooCommerce know when the cart data changes. The final cookie (wp_woocommerce_session_) contains a unique code for each customer so that it knows where to find the cart data in the database for each customer. No personal information is stored within these cookies.
