An Anukari account is not required to purchase or use Anukari. However, once you have purchased an Anukari license key, an Anukari account will let you manage which devices the license key is registered on. For example, if you have registered Anukari on the maximum of 3 devices, an Anukari account will allow you to remove the license from an old device and install Anukari on a new one.
