Your passwords, backup codes, licenses, and private documents — organized and encrypted, not scattered across notes apps and screenshots.
Offline & encrypted · Windows first
Your private things, encrypted and offline.
An encrypted, offline vault for the private things you'd hate to lose — passwords, keys, licenses, and notes. It lives on your machine, never a cloud.
Your vault is a single encrypted file — back it up and carry it between machines whenever you like.
- No account
- No cloud
- Encrypted locally
sticky notes, but civilized Who it's for
For everyone with something worth protecting.
Your everyday private life and your work both live in one local vault — encrypted, offline, and entirely yours.
Not a browser extension — nothing injected into web pages, nothing to phish, nothing syncing behind your back.
Your .env files, API keys, and per-environment config — kept
beside the project that uses them, and exported when your app needs it.
What it holds — and does
One vault for your accounts, files, links, and config.
Keep the private things worth protecting in one place — then let the app organize, generate, and back them up for you.
What you can keep
Accounts & credentials
Logins, usernames, secrets, and profile links for the services you use.
Important links
Dashboards, docs, and consoles — grouped and kept beside the project they belong to.
Secure files & certificates
Store files and certificates, and track which certs are valid, expiring, or expired.
Key-value & config
Environment variables, API keys, and any name-to-value pair, organized by project and environment.
What it does for you
Separate project workspaces
Keep every client, side project, or part of your life in its own tidy workspace — all inside one encrypted vault.
Built-in password generator
Generate strong passwords or memorable passphrases — tune length, character sets, or word count — right where you save them, fully offline.
Environment-aware entries
Label and filter values for local, development, staging, production, or no environment.
Import and export .env
Bring an existing .env file into a project and export one environment when your app needs it.
Local backup and restore
Create encrypted vault snapshots and restore them without an account or remote service.
Recovery Key
Get a Recovery Key at setup. Save it, and you can regain access even if you forget your master password.
Trust, with details
Local-first is a design choice, not a magic word.
LocnLock keeps its responsibilities narrow and tells you where the boundaries are.
Everything is encrypted
Your names, secrets, notes, accounts, and files are scrambled with AES-256-GCM — unreadable without your master password.
Only your password unlocks it
Your master password — hardened with Argon2 — is the only key, and it never leaves your device.
Ten-minute auto-lock
Inactivity clears the unlocked session and returns the app to its lock screen.
Copied secrets don't linger
Copying a sensitive value schedules the clipboard to clear itself after a short window, so a secret doesn't sit there.
A safety net only you hold
We can never unlock your vault — there's no backdoor. But your Recovery Key, saved at setup, can restore access if you forget your master password.
A little non-secret info stays readable
A few details — labels, dates, and ordering — stay readable so search and sorting are instant. Never your actual secrets.

FAQ
Questions worth asking before trusting a vault.
Is LocnLock cloud-based?
No. LocnLock is an offline desktop app. It does not require an account, backend, cloud sync, or telemetry.
Where is my data stored — can I move it?
Everything lives in a single encrypted file in the app's local data folder on your computer — no server, no cloud. To move it to another machine, use the built-in Backup and Restore: export an encrypted snapshot, then restore it on the other device. It stays offline the whole time.
Can I sync across devices?
No — LocnLock has no cloud sync, by design. To use your vault on another machine, move it manually with Backup and Restore. Your data never leaves your device unless you export it yourself.
What exactly is encrypted?
Everything sensitive is encrypted with AES-256-GCM: project names, entry keys, values, and notes, all account fields, and your saved links and files. Only structural metadata stays as local plaintext — environment labels, the sensitive flag, display order, timestamps, and relationships — so the app can sort and filter without unlocking your secrets.
What if my laptop is lost or stolen?
Two different things here. A thief can't read it: your vault is encrypted with AES-256-GCM and only your master password (hardened with Argon2) unlocks it — there's no vendor backdoor, so a stolen vault file stays unreadable, and a strong, unique master password is what protects it. Getting your data back is separate: because everything is local, a lost device means lost data unless you have a backup. Use Backup and Restore to export an encrypted snapshot and keep it somewhere safe — an external drive, or your own cloud storage like Google Drive or OneDrive. The backup is encrypted, so it's safe to store there; just remember it's still only as strong as your master password. LocnLock never uploads anything itself — you choose where your backup lives.
Does it lock itself when I step away?
Yes. LocnLock auto-locks after 10 minutes of inactivity — a fixed window — clearing the unlocked session back to the lock screen. Secrets you copy are also wiped from the clipboard a short time after copying, so they don't linger.
What happens if I forget my master password?
You get a Recovery Key when you first set up your vault. Save it somewhere safe — with it you can reset your password and regain access even if you forget it. There's no vendor backdoor, so if you lose both your master password and your Recovery Key, the encrypted data can't be recovered by anyone.
Master password vs Recovery Key — what's the difference?
Your master password unlocks the vault every day. Your Recovery Key is a one-time backup, generated at setup, that resets a forgotten master password. Keep both safe — lose both and no one (including us) can recover the data.
Is LocnLock a browser password manager?
No. It can store personal credentials, recovery codes, and private notes, but it does not provide browser autofill or account syncing.
Can I use it for a team?
LocnLock is a single-user, local app — there are no shared vaults, accounts, or multi-user features. Each person runs their own local vault.
Can two people share the same PC?
Yes — give each person a separate Windows (or macOS) user account. LocnLock keeps its vault in your own OS user profile, so each account automatically gets its own separate encrypted vault, with its own master password and Recovery Key; the other person can't open yours. A single shared OS login would share one vault by design (there are no in-app profiles), so separate OS accounts are the way to keep each person's vault private.
Will macOS be supported?
macOS is planned for later, via the Mac App Store, but there is no announced release date. Windows is the current distribution target, delivered through the Microsoft Store.
How much does LocnLock cost?
LocnLock is a one-time $29 purchase on the Microsoft Store for Windows. A macOS version is planned for later on the Mac App Store for $34. There's no subscription. It's licensed per platform and includes both personal and commercial use — you may use it for your own work and business, but you can't resell or redistribute the app itself.
Do you offer refunds?
Purchases and refunds are handled by the Microsoft Store under its refund policy — LocnLock doesn't process payments or store any billing details.
Why trust it
Built to be trusted — not trusted blindly.
LocnLock has no ad model, no analytics, and no servers that ever see your data — so there is nothing about you to sell, leak, or lose.
The security isn't "just trust us": the app runs offline and encrypts with standard AES-256-GCM behind an Argon2-hardened master password.
And it's honest about the limits — a weak master password is still the weak link if someone copies your vault file. There is no vendor backdoor, which also means no one, us included, can recover a vault once both the master password and its Recovery Key are gone.
