Hi @steemtaurus, yes we understand your concern as it is still on the early releases and still being audited by the community. Although your private key is properly encrypted at all times, and the data is only stored locally on your computer. Here's an idea, you can download, login and just vote or do a transaction, then log out (on the config menu). This will clear all data afterwards 😊 and then just unistall SimplEOS. The other option is to wait a little longer until you feel safe! But please, just do what you comfortable with :)
