I would just like to install a text editor and spreadsheet that doesn't require crazy permissions (like permission to make phone calls: WTF does a spreadsheet need to make phone calls?!)
Does it need to make phone calls, no. Does it need to monitor phone state, yes. That way if you are editing a document and receive a phone call, it can save your document and go into a hibernation state. Give this thread a read (http://androidforums.com/android-ap...explained-security-tips-avoiding-malware.html), it is very long but well worth the read.
I'm as paranoid about sharing data online as you are which is why I don't sync my data online. Install Avast mobile security (free). Among its many tools it includes a firewall with which you can select - app by app - which apps to block from wifi or any other access. So even if it accesses your phone data the firewall will prevent it from being sent out. A good office package is Kingsoft Office (also free) which is fully compatible with MS Office and contains an editor, spreadsheet and PowerPoint clone. Kingsoft Office Suite for Android and free Office Reader for Android
