The lock does not start, or switches off after a while
Open Touch Blocker, tap Finish setup and allow Display over other apps. On phones that close background apps, turn off battery optimisation for Touch Blocker as the setup check shows.
The status bar or power button still works
That is an Android limit: system areas sit above every app layer. Use Android screen pinning (the app has a step-by-step guide), then lock touch.
I forgot my PIN
Restart the phone. A restart always removes the lock. You can then set a new PIN or turn the PIN off in the app.
I bought Premium but it is not unlocked
Open the Premium screen and choose restore purchases, signed in to the same Google account that bought it. Payments and refunds are handled by Google Play.
How do I delete my data?
Stats, zones, settings and PIN live on your device. Uninstalling the app or clearing its data in Android Settings removes everything.
