How does it work?
Almost every message on an Android phone passes through the notification shade on its way in. With notification access turned on, AppLock Master keeps a copy of each notification as it arrives: who it was from, what it said, which app and when.
Deleting a message later changes the conversation inside the messaging app. It doesn’t reach back into a notification that has already been shown, so the text stays in your history.
Which apps does it work with?
Any app that shows the message text in its notification — WhatsApp, Instagram, Messenger, Telegram, SMS and most email apps. You choose which apps are kept, so a noisy one doesn’t fill the history.
What it can’t recover
How to turn it on
- 01Open AppLock Master and turn on notification history.
- 02Allow notification access when Android asks. This is what lets it keep notifications as they arrive.
- 03Choose which apps to keep notifications from: the apps you’ve locked, or all of them. Notifications still in your shade are saved straight away, and new ones as they arrive.
Hiding notifications from your lock screen
The same access runs the notification blocker. Pick apps whose notifications should never show in the shade or on the lock screen, and nothing previews for someone looking over your shoulder.
Where is the history kept?
On your phone, inside AppLock Master, behind the same PIN, pattern or fingerprint as your locked apps. Clear it whenever you like.
