Why KyberQ?

The Photo Locker Built for Real Privacy — Not Cloud Sync

Most gallery apps upload your files. KyberQ is a local-first secure vault: encrypt photos, hide files, and control every backup yourself.

On-Device Encryption

Your encrypted vault never leaves your phone. No cloud account, no server copies — just strong file encryption you control.

Post-Quantum Security

Kyber512 hybrid encryption protects your vault against today's threats and tomorrow's quantum computers.

Biometric & PIN Lock

Password-protect photos and files with a vault PIN, Face ID, Touch ID, or fingerprint unlock.

Secret Second Vault

Hide sensitive content in a separate secret vault with its own credentials — invisible from your main library.

Intruder Detection

Repeated wrong unlock attempts can trigger an intruder selfie — stored privately on your device only.

Screenshot Privacy

Block screenshots inside the vault so private photos and documents cannot be captured from the screen.

Use Cases

Who Uses a Private Photo Vault & File Encryption App?

KyberQ is built for anyone who needs to hide photos, lock documents, and keep personal data off the cloud.

Hide Personal Photos & Videos

Keep family photos, travel memories, or sensitive images in a password-protected photo locker away from your main gallery.

Secure Work Documents

Encrypt PDFs, contracts, IDs, and financial files on your phone without relying on third-party cloud storage.

Parents & Families

Lock apps and galleries from curious hands with PIN, biometrics, and screenshot privacy enabled.

Travel & Offline Life
