FEMSA uses "cookies" when a User is surfing the sites and Web pages corresponding to the Service.

FEMSA's cookies cannot read data from a User's hard disk or the cookies created by other suppliers. The use of cookie technology allows FEMSA to recognized registered Users after they have registered initially, so that they do not have to register every time they access the areas and services reserved exclusively for them. The User may configure the navigator so that he or she receives a notice on the screen about the reception of cookies and to prevent cookies from being installed on the hard disk. Please consult your browser instructions and manuals for further information. The User does not have to permit the installation of cookies sent by FEMSA in order to use the Service, although in such case the User will have to register every time he or she accesses the Service.
