Used Secure Folder - File Vault for Android?
Editors’ Review
Experience a practical privacy tool, Secure Folder - File Vault by Sigma Smart Technologies, designed to protect sensitive personal information on Android devices. The app creates a secure, encrypted-like environment for hiding photos, videos and documents, and offers PIN, pattern and fingerprint locks plus AI Scan and intruder selfies to detect and record unauthorized access attempts. It also includes a document locker and private space management tools for organizing hidden content.
Creates an isolated vault that removes files from the system gallery
The app centralizes private items into a hidden storage area accessible only through its unlock methods. Users move photos, videos and documents into the vault to keep them out of the device gallery. Supported types include:
- Photos and videos
- PDF and Doc documents
- Notes and other media
Authentication layers combine PIN, pattern and biometric options
Access control offers PIN, pattern and fingerprint unlocking so owners can pick the method that matches their device capability. Fingerprint unlocking functions on compatible devices, and the intruder selfie mechanism captures the front camera image when incorrect credentials are entered. Recorded break-in evidence is stored inside the app for owner review rather than appearing in the standard gallery.
AI Scan provides proactive detection while the vault remains described as encrypted-like
The app's AI Scan automatically identifies files that may need protection and flags them for the user's consideration, adding a proactive layer to manual selection. The developer describes the storage as an encrypted-like environment, suggesting data isolation without asserting a certified encryption guarantee. Third-party platforms and user feedback highlight the intruder alert and straightforward interface as practical points in routine privacy maintenance.
Accessible for casual users yet offers management controls for hidden content
Management tools let non-technical users move and organize sensitive files into private space with guided controls, while the app retains options to sort and maintain hidden content. The developer designed the interface for accessible operation and included private space management tools for ongoing upkeep. Biometric features require modern Android builds, so device compatibility should be checked before relying on fingerprint unlock.
Pros
- AI Scan flags files that may require protection
- Supports PIN, pattern, and fingerprint unlocking on compatible devices
- Intruder selfie captures front-camera evidence of failed access attempts
- Hidden files are removed from the device gallery
Cons
- Storage described as 'encrypted-like', not a certified encryption guarantee
- Biometric features require modern Android builds for operation
- No cross-device sync or cloud backup options mentioned
Bottom Line
Practical for everyday local privacy, with a single encryption caveat
The app is a practical option for Android users who need straightforward local protection of personal files and easy organization of hidden content. A single caveat is the vendor's phrasing of storage as an 'encrypted-like environment', so users who require formally audited or certified encryption should verify technical assurances elsewhere before entrusting highly sensitive data. For everyday privacy use it handles routine file protection tasks without extra configuration.
