Well, EveMon (if you are referring to it) can work with the xml file you can save from the eve-online site (My Character section). No need to put in your credentials if you don't trust them, but I have to note, that as an open source project anyone can verify that they don't post or otherwise manipulate the info you enter there! So, EveMon can help you to plan your skills training and even see what skills are available and decide if you want them (for those that haven't heard of EveMon).
I also use the QuickFit utility, a java application (runs on all type of systems) that allows to fit a ship and run simulations with the capacitor, to see how it will hold on battle, mining etc. You use the former xml file to import your skills and you start using it. Very easy and informative.

Check them out, and if you don't want to use your accounts' credentials, just save the xml form of the skills page on the EVE website.
