The technology behind it? Relatively secure.
In real life? Not so much. The cops can unlock your phone by reconstructing a finger with your print on it. However, if you are quick enough to turn off your phone and your encryption key is sufficiently secure, you should be good.

wondering too is the fingerpringt safly stored? and cant google get it?

Google can't get it. It works on AOSP/Cyanogenmod without any google libraries installed.

A fingerprint is only meant to identify the user, not to be used as a password; it's not secure. This is why your phone asks you to insert your password occasionally and after inactivity.

and is there really no way when someone steals the device or the government has it to get the fingerprint by reading the chip etc.? and is it encrypted ( like aes 256? )

>giving Google, the NSA your fingerprints
Not secure at all, you might as well post your address, specific room you're in, where you work, what you look like, your debit card number, your social security number, and your phone number on every site you go on
