Photo Vault, Hidden Safe Lock

Features & Capabilities

Locker: Secret Calculator is a private vault that hides photos, videos, notes, files, and app links behind biometric protection. You can customize the Locker's app icon to a calculator or timer and unlock it with FaceID, TouchID, or a PIN. All data is stored on-device and never uploaded to servers.

Note: If you choose not to set up FaceID/TouchID and you forget your PIN, you may lose access to Locker and data recovery isn’t guaranteed without a backup. All data stays on-device and is not accessible by Locker developers. The app also offers an optional Premium Pass with a free trial and auto-renewing subscription; privacy policy and terms are linked in the app.

User Reviews

Reviews repeatedly cite broken iCloud backups and transfer data loss, plus confusion around lifetime subscription terms. Users want subfolders for better organization and report painful device migration and PIN reset experiences with poor support. Security concerns about bypassing locks are noted by some. On the plus side, the app has a clean interface and can access hidden files, but these positives are outweighed by the recurring reliability and usability issues.

Pros

Clean, intuitive user interface
Ability to view and copy hidden files on the device
Longstanding usage with minimal hitches (some users report stable operation)

Cons

iCloud backup/restore often fails and can lead to data loss when transferring to a new device
Lifetime subscription terms are unclear or not honored (promos missing or restore failures)
Lack of folder/subfolder organization for files and media
Migration to a new phone and PIN reset issues with little or slow support
Security concerns about easy bypass to access locked apps

I paid for a lifetime subscription in 2021. I deleted the app a few months ago and I downloaded it back and I tried to restore purchase but it keeps saying restore purchase not found. Why have I paid for a lifetime subscription and I still get no restore purchase?
