Lock notifications and protect your messages with PIN security
Hide Notification Content & Privacy Screen Guard – Notification Lock Looking for a reliable way to hide notifications, lock notification shade previews, and keep private messages safe from prying eyes? Notification Lock - Screen Guard gives you control over privacy and sensitive message preview alerts. Whenever a new notification arrives, our smart notification blocker and vault intercepts it, encrypts the message content locally on your device, cancels the original status bar alert, and replaces it with a neutral, locked stub. Notification Lock app allows you to read the real chat preview only when you enter your secure PIN. Key Features of Notification Lock App: • Notification Vault & Encryption: Every notification alert is instantly saved into an encrypted on-device notification log behind a secure PIN code lock. • Neutral Notification Shade Stubs: Clear original system notifications and replace them with a locked, blurred stub. No message preview, no text leak, no unwanted peeking. • 4 Custom Privacy Tiers: - Pass Through: Normal preview without hiding. - Sender Only: Displays who sent the chat message without showing the text content. - App Only: Shows which application pinged you, keeping message content hidden. - Anonymous: Masks everything; every row displays as a neutral locked alert. • Desk Guard Auto-Mute: Put your phone flat on a desk, and notification alerts automatically go quiet. Pick your device up, and alerts resume instantly. • Privacy Display Angle Tint: Darken your screen automatically as you tilt your phone or on demand when handing your mobile device to friends. • Notification Insights & History: Track notification count, identify noisy apps, and clean up notification history logs. Why Use This Notification Locker? Whether you are in public, sharing your screen, or sitting at a busy office desk, unwanted notification popups can compromise your personal privacy. Notification Lock - Screen Guard masks status bar previews, silences noisy popups, and protects notifications easily.
