It's a local wallet.
But you can't encrypt it, if I'm not wrong. Hence my initial question.
Your question was is there a reliable wallet. It is reliable in that it works for balances and transactions but it doesn't feature encryption yet. They're not even officially at beta stage yet so you have to cut them some slack on this!
If you want encryption in the meantime you could store the ./libryum folder on an encypted disk image which you mount when you want to use the wallet and point a symlink to that image.
I was only asking, not demanding. I fully understand their situation, didn't mean to be rude
