## Description

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.

## Review summary

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
