In addition to Gavin's answer, fingerprints are not "hashed". It's because hashes have a property that if the input changes even by the slightest of the bit, the resulting hash changes completely. Fingerprint sensors in phones do not capture the exact same fingerprint everytime you place your finger on it.
Instead, the fingerprints are encrypted and stored in the phone.
Also, according to Apple:
Touch ID can be trained to recognize up to five different fingers. With one finger
enrolled, the chance of a random match with someone else is 1 in 50,000.
So, hopefully, even if we assume that they can retrieve the fingerprints from users' devices, they can't identify people with 100 percent surity based on the fingerprints stored.
