The Funnelify App default domain funnelify.net redirects to http://funnelify.net/login which doesn't have SSL. So it would show as Not Secured on your browsers. But it's completely fine. It's a builder not your website. You can install SSL from your hosting/DNS provider when you publish your websites.
However, SSL is installed in our main server. So, if you want you can force the Funnelify Builder to use SSL. Simply add https:// before the builder domain and visit https://funnelify.net. It will use SSL and builder URL will show as secured on your browsers.
Note: If you decide to force SSL on your builder URL, make sure you do it on all of your pages and sites. Ideally, you should always use the SSL URL https://funnelify.net. For best practice, clear cache, cookies and history of your browsers and bookmark the SSL URL https://funnelify.net for future use.
