About this app

Micro Guard™ helps you block apps from using your Android phone’s microphone when you don’t need it.
Switch to Mic Off with one tap, decide which apps are allowed to use your mic, and review microphone access with logs and alerts. Micro Guard is designed for simple microphone control, privacy and protection during meetings, calls and travel.

When protection is active, Micro Guard helps block unwanted microphone access, records microphone events in a logbook and notifies you about suspicious behaviour.

Core microphone protection
• One-tap Mic Off: turn microphone access off fast and turn it back on when needed
• 24/7 microphone blocker / mic lock: keep the microphone locked when you are not using it
• Whitelist & app control: allow trusted apps and block unknown apps
• Deep Detective™ Lite: smart engine that monitors microphone access and helps detect unusual behaviour
• Logbook & alerts: see microphone access attempts and get notifications if something tries to listen in the background
• Microphone permission list: review which installed apps have mic access
• Passcode protection: secure the app so nobody can change your settings
• Home screen widget & quick toggle: enable or disable protection with one tap
• Modern UI with dark mode

Deep Detective™ anti-spyware scanner (PRO + subscription)
Upgrade to Micro Guard PRO and subscribe to unlock Deep Detective™ Live — a real-time anti-spyware scanner designed to help detect stalkerware, spyware and other threats that try to access your microphone.
The live spyware scanner uses advanced heuristics and a large signature database to help identify both known and emerging threats.
Subscriptions are optional and can be managed in your Google Play account. The core microphone blocker remains available in the base version.

How Micro Guard works
• With protection enabled, apps and system processes that are not on your whitelist can’t access the microphone
• Temporarily allow access for calls, voice messages or recordings, then switch back to Mic Off afterwards
• Every access attempt is recorded in the log so you can review what happened on your device
• Designed to work alongside your existing antivirus, firewall or anti-spyware apps

Who Micro Guard is for
• People who want a simple way to block apps from using the mic
• Online meetings & video calls: reduce background recording risk
• Journalists, lawyers, doctors, creators and business users who handle sensitive conversations
• Travellers and people who use public Wi-Fi or untrusted networks

Privacy, trust & permissions
Micro Guard is not a voice recorder. It focuses on on-device microphone access control and security logging.
To help enforce microphone blocking across your device, Micro Guard uses Android permissions such as Device Administrator and Accessibility services. These permissions are used only for security features like blocking, logging and detection, and you can revoke them at any time in Android settings.

Micro Guard is developed by Protectstar™, the company behind apps like iShredder™ and Antivirus AI.
More details are available in the in-app privacy policy and in the Data safety section on Google Play.

Important limitations
Micro Guard blocks access to the microphone on your device. It can’t control what happens once audio leaves your phone — for example, calls that may be recorded by your carrier or by the person you are talking to.
For sensitive calls, we recommend using secure, end-to-end encrypted communication apps in addition to Micro Guard.

Take back control of your microphone with Micro Guard.

When you see how many applications are turning on your microphone 24/7 you will be stunned. But if you want to get that control back in your hands then look no further! Microphone Blocker & Guard is excellent! Packed with lots of solid proven technology and exceptional features, it's going to be an application you will never regret purchasing. I've used Protectstar products for years and recommend them to anyone looking to have their right to privacy given back. Loyalty is rewarded too! 10/10

This app turns off at random throughout the day. Sometimes the menu says it's on but the drop menu says it's off. Don't buy it. It would be better to buy a hardware microphone lock device. They are around the same price as this app.

Free version basically unusable. Paid version seems to do the job so I raised my rating to 3 star because of bug. It does not start up automatically despite setting to do so. I wrote to the developer twice but no reply. Fix this and I'll give you 5 star
