Yes you do.
Unlike Wix, Site Builder, Weebly and other online “build your own website” platforms.
You cannot move your website from them and, in the worst case scenario, if they went bust you would lose your website.
Remember, if they put their prices up you will have no option but to pay up or again lose your site.
Once your website is built and paid for you can host it with us or have it hosted on your own website hosting partner,
