FileStasher

FileStasher is a private, on-device file vault that keeps your documents, photos, and sensitive files encrypted and out of reach — from everyone.

Every file you store is protected with strong AES-256 encryption, the same standard used by banks and governments. Your files never leave your device unencrypted. Not even Apple can read them.

WHAT MAKES FILESTASHER DIFFERENT

• DUAL VAULT — PLAUSIBLE DENIABILITY [Premium]
A real vault and a separate decoy vault, each with its own passcode. If you are ever pressured to unlock the app, the decoy opens without revealing your real files — true plausible deniability, built in.

• STRONG ENCRYPTION
Every file is encrypted with AES-256 before it touches storage. Your encryption key is derived from your passcode using a slow, hardened process that makes brute-force attacks impractical.

• FLEXIBLE AUTHENTICATION
Choose how you unlock your vault:
— PIN only
— Face ID / Touch ID only
— Face ID / Touch ID + PIN together
Repeated failed PIN attempts trigger a temporary lockout to stop guessing attacks.

• TWO-FACTOR AUTHENTICATION [Premium]
Add a second layer of security using any standard authenticator app. Emergency backup codes ensure you are never locked out permanently.

• IMPORT FROM ANYWHERE
Use the share sheet to send files directly into your vault from any app — Files, Safari, Mail, Photos, and more. Or use the built-in document picker and photo library import.

• ORGANIZED YOUR WAY
Create color-coded folders to organize your vault. Nest, rename, and move folders, or multi-select files for batch export, move, or delete.

• BUILT-IN PDF VIEWER
Read multi-page PDFs directly inside the app with full-text search, result highlighting, and zoom. No need to export files to read them.

• ICLOUD BACKUP — END-TO-END ENCRYPTED [Premium]
Optionally back up your encrypted vault to iCloud. Files are encrypted before they ever leave your device, so even Apple cannot read your backup. Restore from any saved snapshot.

• AUTO-LOCK
FileStasher automatically locks after a configurable period of inactivity or whenever your device locks — so your vault is always protected, even if you forget.

• SECURE DELETION
When you delete a file, FileStasher overwrites it before removing it from storage. Files are properly wiped, not just unlinked.

• ACCESSIBILITY FIRST
Full VoiceOver support, dynamic type, and accessibility labels throughout.

PRIVACY BY DESIGN

FileStasher collects zero data about you. No analytics, no tracking, no network requests. Everything happens on your device.

• No account required
• No cloud sync (iCloud backup is opt-in and end-to-end encrypted)
• No ads, ever
• No data sold or shared
