You can HIDE the (really stupid) blue Badge from your site front-end, without paying a fee:
In Sumome plugin > Settings > Badge, set Location to Hidden.
But be aware that this ALSO hides the Badge in WP ADMIN too — so there’s no way to get back to the plugin Settings anymore, until you UN-hide the Badge.
To UN-HIDE the (really stupid) Badge:
The easiest way is to manually add “#/sumome/app/login” to the end of any URL (preferably while you’re in WP Admin).
There are three other ways, all insanely stupid, as documented on an obscure help-doc that I luckily managed to find:

The List-Builder add-on is pretty good, but the overall SumoMe plugin / service is HORRIBLE.
