How are fingerprints kept secure on Android phones that use them instead of a password?

Some new Android phones use fingerprints to unlock. I’m not sure how much I like a company having my fingerprints on file, What protection is there to keep fingerprints secure on those devices?
Ultimately when it comes to security there is rarely a right answer. Nothing is completely secure. But some options are better than others. A four-digit passcode is better than no screen lock at all. A longer alphanumeric password or fingerprint scanner is better still
