About this app

Micro Guard™ is a microphone blocker & anti-spy app that helps stop apps, hackers and spyware from listening through your device’s microphone.
Turn on microphone protection with a single tap and decide exactly which apps are allowed to use your mic. As a powerful mic blocker, it helps you quickly disable the microphone whenever you’re not using it.

When protection is active, Microphone Blocker & Guard blocks unwanted microphone access at system level, logs every access attempt and alerts you to suspicious activity – so you stay in control of your privacy.

Deep Detective™ anti-spyware scanner (PRO)
Upgrade from the free edition to Micro Guard PRO and subscripte to unlock Deep Detective™ Live, a real-time anti-spyware scanner designed to detect stalkerware, and spyware that try to access your microphone. The live spyware scanner uses advanced heuristics and a large signature database to help identify both known and new threats.

How Micro Guard works
• When microphone protection is enabled, apps and system processes that are not on your whitelist cannot access the microphone
• You can temporarily allow access for calls, voice messages or recordings and block the mic again afterwards
• Every access attempt is recorded in the log so you can review what happened on your device
• Micro Guard is designed to work alongside your existing antivirus, firewall or anti-spy/anti-spyware apps

Who Micro Guard is for
• People who join online meetings and video calls and want to be sure nothing else records in the background
• Journalists, lawyers, doctors, creators and business owners who handle confidential conversations on their phones
• Travelers and frequent flyers who use public Wi‑Fi and untrusted networks
• Anyone who wants an extra layer of microphone privacy on top of Google Play Protect and their antivirus

Privacy, trust & permissions
Micro Guard uses powerful Android permissions such as Device Administrator and Accessibility services only to enforce microphone blocking reliably across your device. These permissions are used for security features such as blocking, logging and detection, and you can revoke them at any time in the Android settings.

Microphone Blocker & Guard app is developed by Protectstar™, a multi‑award‑winning cybersecurity company behind apps like iShredder™ and Antivirus AI, trusted by millions of users and certified by independent organizations. Our security apps protect sensitive data for private users, enterprises and even government agencies worldwide.

You can find more details 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 cannot 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 and protect your conversations from unwanted listening with Micro Guard.

Ratings and reviews

Excellent collection of security apps!! Although I've not managed to get hacker off my devices yet, these programs give me clear and detailed log files, of setting changes, app installs or app removals. They are just another added layer of security, and the more layers you have, the more difficult it is to take control of your device. For example I can see late at night maintence mode has been enabled and booted into. Although the log file ends there on that day, it made me aware of tampering.

The app is great! But I purchased the lifetime, yet Google is still charging me monthly? I paused you guys, playstore, to get it worked out. In my app it says I did purchase lifetime, so you'd better not turn it off on me! I remember doing that quite awhile back, but curious why it was still being billed.. No wonder my bank didn't want to give the money for it. I fight disabilities, please fix this. I don't appreciate having to fight this as well.. Thank you for your attention to this matter 🤓

I was using the free version of this app and it seemed quite useful, so I thought I would upgrade and try the full version. However, the app simply doesn't work. I turn the protection on manually and it is fine. This can be tested by using the voice recorder on my device which doesn't record at this point. Unfortunately as soon as I make or receive a phone call it stops working. The app still shows as being protected, but I can use apps to record and save sound. Disappointing waste of money.
