AkuraiGeo requires your website traffic to be routed through Cloudflare because it uses information from a request header provided by Cloudflare.
Cloudflare provides a lot of products and solutions to build cloud infrastructures, applications and websites. Among many others, Cloudflare provides services like DNS management, global CDN, SSL certificates, etc.

To make sure the necessary information is provided by Cloudflare, visit your dashboard, select the website you want to enable IP Geolocation for, select "Network" on the left sidebar and scroll down to "IP Geolocation" section and make sure to toggle the button on.
AkuraiGeo plugin uses the country code of your website's visitor's IP address directly. It doesn't use the IP address, doesn't get it from anywhere and therefore can't store it anywhere.
