AES-256, in this browser
Files are sealed with AES-256-GCM before they are stored. The vault key stays in memory only while you are unlocked.
FULLFORCE LTD · Local AES-256 · No account
A private vault for the documents you do not want online.
locallock.app seals files in this browser, the way a vault holds paper: closed until you open it. Nothing is uploaded unless you send a copy that is already sealed.

The door was steel. The record stayed inside.
Public-domain photograph of the safe deposit vault. locallock.app keeps that rule: the sealed file does not leave this device.
1
Drop a file
PDF, photos, text, Office documents — the type does not matter.
2
It is sealed here
Your password wraps a random vault key. The file name is encrypted too.
3
Open it inside locallock.app
Or take a .llock file with you. The unlocked original stays put.
A vault, not a password-protected zip.
Zip encryption is easy to misuse and eager to unpack. locallock.app keeps documents sealed and shows them only after the vault is open.
Read without exporting
Open PDFs, images, text, audio, and video inside locallock.app. An unlocked copy is written only when you explicitly save one.
Password, PIN, or this device
Use a password, an optional PIN, and — where the browser allows — Windows Hello, Touch ID, or a device PIN.
Batch and folders
Drop a handful of files or a whole folder. Folder names stay inside the encryption.
Locks when you step away
locallock.app locks as soon as you leave the tab, and again after an idle timer. The key is dropped from memory.
Backup only what is sealed
Optional backup sends a .llock file you already encrypted. Plain documents are never uploaded.
Inside the vault
Your files never leave this browser unless you choose to send a sealed copy.

Questions
Do my files leave this device?
Not by default. Sealed documents live in this browser’s private storage. locallock.app only makes a network request if you turn on encrypted backup or start a Pro checkout.
What if I forget the password?
The emergency code created with the vault can open it and let you set a new password. locallock.app cannot reset a vault. There is no copy of your password anywhere else.
Is a PIN as strong as a password?
No. A short PIN is convenient and easier to guess if someone copies the vault storage. Use a long password as the real key, and treat the PIN as a shortcut on a device you control.
Can I open a sealed file on another computer?
Yes. Download a .llock copy and open it in locallock.app with the export password. The filename sits inside the ciphertext, not in the clear.
What happens when the trial ends?
Free stays open: 8 documents, 20 MB each. Pro is included for 14 days, then $29 once. Pro adds unlimited files, folders, batch sealing, and backup. It does not renew. FULLFORCE LTD cannot open the vault.
How does Windows Hello fit in?
locallock.app is a local web vault, not a WinUI installer. On Windows, Edge and Chrome can use Windows Hello as the device authenticator. If that API is missing, the password still opens the vault.
On this device
Open the vault.
No installer. No account. Create a password, save the emergency code, and seal the first document. Free stays. Pro is included for 14 days, then $29 once.
