Not to be sceptical, but here's my initial impression. Try the "privacy" link at the bottom of their homepage.
> Page not found (404) > Request Method: GET > Request URL: http://flowx.io/privacy/ > Raised by: wagtail.core.views.serve
> You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
They tout excellent app UX but the website has a lot of rough edges visually.
Again, not discounting their work. I'm still going to install and try out, but initial impressions matter.
