Your Passwords Never Leave Your Device
OwlCrypt is an offline password vault that stores credentials, payment cards, identities, secure notes, and TOTP codes — all encrypted locally on your Android device. No cloud. No account. No tracking. Complete control over your data.
Why Choose Offline?
Most password managers upload data to the cloud, creating privacy risks and requiring subscriptions. OwlCrypt is different:
100% Offline — Your data never leaves your device
No Account Required — Start immediately, no sign-up
Zero-Knowledge Security — AES-256 encryption + PBKDF2
No Subscriptions — One-time Pro purchase, no recurring fees
Complete Data Ownership — You control your vault, always

AES-256 Encryption — Industry-standard protection
PBKDF2 Key Derivation — Protects against brute-force attacks
Android Keystore — Hardware-backed biometric security
Biometric Unlock — Fingerprint or face recognition
Auto-Lock — Locks when idle or on app exit
Clipboard Auto-Clear — Passwords cleared after 30 seconds
