So if i wanted to how would i get my encrypted wallet out of their database so they no longer had it?
Once someone "knows" something, you can't really ever count on them to "un-know" it.
As Stephen Gornick already mentioned:
You can click archive on an address and then from the archive view delete the address and private key.
But that still leaves the key around in your backups.
For true secure transfer (to keys that have never been known to an online, network connected system), create new keys offline and do a send transaction so the funds are transferred there.
