Hi,
HikaShop includes a registration view so we can ask for more information during the registration process (like the address).
But it does not mean that HikaShop manages the Joomla accounts.
Please look at the link given by Nicolas. It explain how modify Joomla and how access to the Joomla user profile in the front-end.

By the way, do not send me private message, use the "contact us" form instead.
