No buttons it's completely designed around full screen web interaction using your device back button to go back. No tabs so it keeps a very simple clean UI. We also don't allow scripts on web pages scripts are automatically blocked to save time and to increase security so it's just web browsing only. No history is saved in the browser keeping it extra private and personal. It's only between you and web the way that it's meant to be. Everything is private. Internet is the internet so just be careful content wise sometimes.
