Passphrase: Voice Screen Lock

Never lose your phone again. Passphrase turns your voice into your screen lock — say your secret phrase to lock your phone, and say it again to unlock, completely hands-free. No reaching for a button.

Set it once and forget it. Passphrase listens quietly in the background and locks the moment it hears your phrase. Misplaced your phone around the house? Just clap twice and it rings — even on silent.

WHAT YOU CAN DO
• Lock your phone with a spoken phrase — no tapping
• Unlock with your voice, hands-free
• Choose your own secret lock and unlock phrases — pick words only you would say
• Backup PIN — a simple fail-safe so you're never locked out
• Clap to Find — clap twice to make your phone ring and flash, even on silent
• Calibrate sensitivity, sounds, flash and vibration to suit you

PRIVATE BY DESIGN
Your voice is processed entirely on your device. Passphrase recognises your phrase locally — your audio is never recorded, stored or uploaded. It downloads a small voice model once during setup, then works offline for voice recognition.

WHY PASSPHRASE
• Hands-free when cooking, driving, working out, or your hands are full
• A faster, more natural way to lock and unlock
• Peace of mind with a backup PIN that always lets you in
• Clean, calm, ad-free design — made in India

PERMISSIONS WE USE
• Microphone — to hear your lock/unlock phrase and claps (processed on-device, never uploaded)
• Display over other apps — to show the lock screen
• Notifications — to show the ongoing status notification you can stop
• Battery optimisation exemption — to keep listening reliably in the background
