This is just an account manager that starts the exalt client using the needed startparameter (basicly a connect string with the login data as base64). It also does allow you to have multiple exalt instances running at the same time (if the deca-exalt launcher is not open and no instance is started using it).
If you want, you can have the source code and look in it yourself - there is no keylogger in it. It does save you credentials into a file onto your computer tho (Encrypted using AES 128), but that is by design of course. It will only save credentials you enter into the EAM.
If you have more questions please let me know.
