Frequently Asked Questions about Biometric Security & Local Privacy
Do you store my fingerprint?
No. Biometric authentication is handled entirely by your Android operating system's secure hardware. Kestro never sees your fingerprint data.
Can Craftylane Studios see my bank accounts?
No. Kestro has zero connection to your bank credentials or accounts. We only store the numbers you deliberately enter into the ledger.
