Can I turn Zoho Personal off?

Can I turn Zoho Personal off?

I would prefer to sign in to Zoho and stay at zoho.com.  I like it better than Zoho Personal. I don't like the extra bit of real estate I lose on the top and the left when working INSIDE Zoho Personal. For switching apps, I prefer the "switch to" link in each individual app (although I wish Zoho Invoice was included on that list). 

Is there any setting I can change to make it so I don't automatically log in to ZOHO personal from the home page?

OR, if I HAVE to log in to zoho personal, is there any way to delete the apps I don't use, like the calendar, email, tasks, and viewer?

Thanks.

Daniel
