The App Lockr
The App Lockr locks any app behind your phone's own fingerprint or PIN — WhatsApp, photos, banking, whatever's yours. No account, no cloud, and — uniquely — no internet permission at all, so what you lock stays your business.
Real screenshots from the app — tap any of them for a closer look.
Protection is one big switch — flip it and every app you chose is behind your fingerprint. Pause it just as fast. It's your phone; the locker never argues.
Every installed app in one list — flip a toggle to protect it, search finds anything in a keystroke. Lock three apps or thirty; change your mind any time.
Each permission is asked for in plain words — what it does, and what it can't do. Nothing is granted silently, and Settings shows you the list any time.
It uses the fingerprint or PIN your phone already has — no new password, no recovery questions. And it speaks 8 languages, each written natively.
Every design choice serves one promise: what you lock stays your business.
The app doesn't request internet access in its manifest — anyone can verify it. It literally cannot report which apps you lock, to us or to anyone.
Unlocking is Android's own biometric prompt. The App Lockr only ever hears "yes" or "no" — nothing about your fingerprint is stored, by us or in the app.
Hand your phone over and the moment the screen turns off, every locked app is locked again. No timers to configure, no session left open.
Protection is a switch, not a ceremony. Turn it off for a minute, back on after — your app choices are remembered exactly as you left them.
Usage access only tells the locker which app comes to the front — never what's on screen or what you type. With no internet permission, there'd be nowhere to send it anyway.
English, Deutsch, Español, Français, Italiano, 日本語, 한국어, 中文 — each written natively for its audience, not machine-translated.
No jargon required — but the details are here for the people who want them.
Android apps must declare their permissions, and The App Lockr never declares internet access — a fact anyone can check, not a promise in a policy. Our build fails automatically if that permission ever sneaks in through a dependency.
The biometric check is Android's own system sheet. The app receives a pass or a fail — never fingerprint data, which stays inside your phone's secure hardware where it always was.
It's read for one fact: which app just came to the front, so a locked one can be gated. Not what's inside, not for how long, not a history — and nothing is ever logged.
"Display over other apps" lets the lock screen step in front of a protected app the instant it opens. That is the only thing the overlay is used for — it never draws over anything else.
Locked apps re-arm the moment the display sleeps, so an unlocked session can't outlive the hand you put the phone in.
An app locker guards your privacy from the people around you — it isn't full-disk encryption. Someone who knows your phone's own PIN could uninstall it. For everyone else, your apps are simply shut, and we'd rather tell you that plainly.
