File managers forgot
what files are for.
Cluttered UIs. Ugly defaults. No privacy. Sharing requires three apps and an account. It shouldn't be this hard.
The Ugly Default
Tiny icons. Confusing tree views. No previews. Every file looks the same, every folder is a maze. You shouldn't need a degree in UX to find the document you saved ten minutes ago.
Your files deserve better.
The Sharing Nightmare
Email hits size limits. Cloud shares require accounts. AirDrop only works in the ecosystem. Messaging apps compress everything. Sharing a single file to a single person requires five steps and a prayer.
Sharing should be instant.
The Open Shelf
Every app, every backup tool, every person who picks up your phone can see everything. Medical records. Financial documents. Private photos. All sitting in plain view, readable by anyone with storage access.
Private files need real locks.
Built for your files.
Private by design.
Beautiful File Browser
Fluid grid and list views with smart previews. Toggle between layouts with a tap. Your files have never looked this good — and you can actually find them.
Instant File Sharing
Share any file in one tap via link, QR code, or direct transfer. No accounts needed. No size limits imposed by the app. Share history keeps recent transfers one tap away.
Smart Organization
Folders, favorites, recents, and search. Organize your files the way you think about them. Everything in its place, everything reachable in seconds.
AES-256 Locked Folders
Sensitive files encrypted with AES-256 GCM. Decryption in memory only — no plaintext ever touches storage. Invisible to file browsers, backup tools, and physical attackers.
PIN-Protected Vaults
Folders that lock behind a PIN. Keys derived from your PIN via PBKDF2 — not stored. After 3 wrong guesses, the vault self-destructs and keys are destroyed. No recovery — by design.
Screenshot Protection
OS screenshot API blocked inside locked folders. Content won't appear in the recent apps switcher. What's in the vault, stays in the vault.
Some files are
nobody's business.
Medical records. Financial documents. Private photos. Legal contracts. Lock them in a PIN-protected vault — they vanish from the main view and re-encrypt with a key derived from your PIN. Only you can open them.
For anyone who just
wants their files to work.
