02 — Evidence · Intruder camera

Wrong code? Say cheese.

After repeated wrong attempts, the front camera takes a photo of whoever is trying — saved with the time and the app, on your phone.

05 — Clearance request

Every permission, and why.

An app lock needs more access than most apps, so here is each one, what it’s for, and when you’ll see it.

RefPermissionWhat it’s forWhen it’s asked
P-01Usage accessSeeing which app is opening, so the lock appears before the app does.At setup
P-02Display over other appsDrawing the lock screen on top of the app you opened.At setup
P-03Notification accessKeeping notification history, and hiding previews for the apps you choose.Only if you turn those on
P-04CameraTaking the intruder photo after repeated wrong attempts.Only if you turn intruder selfie on
Stays on your phoneYour PIN, pattern, security question, locked-app list and intruder photos aren’t uploaded. There’s no account to create.
Your phone’s own biometricsFingerprint unlock uses Android’s biometrics — the app is told only whether it matched.
Free, and honest about itThe app shows ads and uses analytics and crash reports. The privacy policy names each service and what it receives.
06 — The interrogation

Questions people ask.

Straight answers, on the record. Something missing? hello@jomostudio.tech

Q.01Does it work with WhatsApp and Instagram?
A.

Yes. It locks any app installed on your phone: WhatsApp, Instagram, Facebook, Telegram, your gallery, messages, banking apps, even Settings and the Play Store.

Q.02Can someone just uninstall it?
A.

Not if uninstall protection is on. Your passcode is asked for before the uninstall screen and the permission settings open, so it can’t be removed behind your back.

Q.03What if I forget my PIN?
A.

Answer the security question you set up, then choose a new PIN or pattern.

Q.04Will it slow my phone down or drain the battery?
A.

It waits in the background for a locked app to open and does very little otherwise, so in everyday use the difference in battery is hard to notice.

Q.05Does it keep working after I restart my phone?
A.

Yes. It starts again on its own after a restart.

Q.06Is it free?
A.

Yes, AppLock Master is free to download on Google Play. It shows ads to stay free.
