Your passwords
never leave
the phone.
LockIt is a password manager that lives entirely on your phone — no cloud, no account, no sync server, because there isn't one. Unlock it, add what you need to remember, and it locks itself again when you're done.
Direct APK, ~50 MB, not on the Play Store — that's normal for a tool like this. Requires Android 5.0+.
A password manager that stays put
No account to create, nothing to sync. Everything happens on the device that's already in your hand.
Set a master password
Once, the first time you open the app. It's never stored anywhere — only used to derive your encryption key, in memory.
Add what you need to remember
Logins, wifi passwords, notes — anything. Each entry is encrypted the moment you save it.
Copy what you need
Reveal a password, copy it, and it clears itself from your clipboard about 30 seconds later — no need to remember to do it yourself.
It locks itself
Background the app, or just leave it a couple of minutes. LockIt locks automatically, every time.
Everything, right where you'd expect it
Every entry, one tap away
Labels and notes in plain view, passwords masked until you ask. Copy either one and it clears itself from your clipboard about 30 seconds later — automatically, without clobbering something else you copied in the meantime.
Two switches. On your terms.
The local server is off until you turn it on, and stops the instant the vault locks. LAN access is a separate, explicit opt-in — with a warning before you ever turn it on.
Want a bigger screen? That's optional.
Everything above is all most people ever need — LockIt is a complete password manager on its own. This part's for people who specifically want to glance at their vault from a laptop and are comfortable getting there themselves.
Off by default. On your terms, if at all.
Flip "Enable local server" in Settings and the app serves the
vault on 127.0.0.1:8080 — reachable only through a
USB connection, not the internet. Getting a port forwarded to it
is up to you: run adb forward tcp:8080 tcp:8080
yourself, or use the small connector script included in the
project if you'd rather not type that out each time. Neither is
required, and most people never touch this section at all.

The whole spec, in one place
No trust-us marketing copy — this is the actual mechanism, so you can decide if it's enough.
What this is — and isn't
Do I need to plug in my phone to use this?
No. LockIt is a complete password manager entirely on the phone — the browser/USB option is a separate, off-by-default feature for people who specifically want it and are comfortable setting up their own port forward. Most people never touch it.
Is there a cloud backup?
No. That's the point. If you lose the phone and forget the master password, the vault is gone with it — nobody, including us, can recover it. Use the built-in encrypted backup file if you want a copy somewhere else.
Why isn't this on the Play Store?
It's a direct APK install by design — a small, auditable tool for people who'd rather read the code than trust a store listing. Sideloading needs "install from unknown sources" enabled once.
Does it work on iOS?
Not yet — this version is Android only. iOS and other platforms aren't ruled out, just not built yet.
Should I turn on "Allow LAN access"?
Only if you actually need it. It's off by default, and turning it on trades the physical USB requirement for reachability over your whole Wi-Fi network — still password- and token-gated, but a bigger attack surface. Read the in-app warning before enabling it.
What's the connector script?
An optional convenience for the browser feature above — it watches for your phone over USB and forwards the port automatically. It's not distributed with the app and isn't required; anyone comfortable with adb can just forward the port themselves.
One phone. One vault.
No account, ever.
Everything encrypted, everything local, nothing to sync.
