Encrypted file manager
Secure File Manager
Organize your files, see what fills your storage, and lock private ones in an encrypted vault.
Your files, your device
Secure File Manager keeps confidential documents, photos and media encrypted on the phone itself. Vault keys are generated inside the Android KeyStore, so nothing is derived from a password that could leave the device.
There is no account, no remote server and no analytics. When you want to hand a file to another device, the app shares it over your own Wi-Fi network, behind a PIN.
Secure File Manager is in development and not yet released.
Inside the app
01
Hardware-backed vault
Files you move to the vault are encrypted with AES-256-GCM, using keys held in the hardware-backed Android KeyStore. Unlocking takes your fingerprint or face.
02
Local first
No account, no remote servers, no data analytics. Nothing is uploaded to a cloud; files leave the phone only when you share them yourself over local Wi-Fi.
03
Browse by type
Go straight to images, videos, documents or archives. Files are indexed, so each category opens quickly.
04
Storage analysis
See what is using your storage in a chart, and find duplicate and large files. All scanning happens on the device.
05
Local Wi-Fi sharing
Share files with another device on the same Wi-Fi network through a temporary local server, protected by a PIN generated for the session. No cloud relay.
How it's built
An Android app. Vault files are encrypted with AES-256-GCM using keys kept in the hardware-backed Android KeyStore, and wireless sharing runs a temporary HTTP server on your local network.
