ELI5:With finger scanners on smartphones becoming more common, where is that information of your print going?
gpt
Virtually all modern smartphones never share the fingerprint data with the software on the phone. The fingerprint data is kept on a special chip inside the phone and the operating system and the rest of the apps on the phone just ask it to either learn a new fingerprint, or detect whether the current fingerprint matches one previously recorded.

The idea is that a bug in the operating system or a malicious app shouldn't be able to steal your fingerprint data and upload it somewhere. When you get a new phone, you have to train it on your fingerprints again.

The only way somebody might be able to steal information about your fingerprints is if they physically stole your phone.
