Micro Guard Microphone Blocker v6.5
Protectstar Inc.About this app
Developer Description
Microphone blocker & microphone disabler: mic off + anti-spyware protection.
Turn on microphone protection with one tap and decide exactly which apps are allowed to use your mic. As a powerful mic blocker and microphone disabler, Micro Guard helps you turn off the microphone (mic off) whenever you don’t need it.
When protection is active, Micro Guard blocks unwanted microphone access at system level, logs every access attempt and alerts you to suspicious behavior – so you stay in control of your privacy.
Why a microphone blocker?
Apps can request mic permission at any time. Use Micro Guard to disable your microphone when it’s not in use.

How Micro Guard works
• When microphone protection is enabled, apps and system processes that are not on your whitelist cannot access the microphone
• Temporarily allow access for calls, voice messages or recordings, then block the mic again
• Every access attempt is recorded in the log so you can review what happened on your device
• Designed to work alongside your existing security apps
Who Micro Guard is for
• People who want to prevent apps from listening when the mic is not needed
• Online meetings and video calls: reduce background recording risk
• Anyone who handles sensitive conversations on their phone
• Travelers 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 reliably 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 functions (blocking, logging and detection) and you can revoke them at any time in Android settings.
Micro Guard is developed by Protectstar™, a multi‑award‑winning cybersecurity company behind apps like iShredder™ and Antivirus AI.
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.

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.
I re-installed Microphone Blocker and followed your advice. It worked. Maybe I made a mistake or something. The app is good and complex, although it only block Applications and not the System apps, which is more important (on the free version). Maybe on Premium, it will do better. Thank you.
Keeps crashing. If I use the video recorder or voice recorder, the apps clearly still have access to my mic. And neither are on my whitelist. So I cant say this app is working...
the interface looks really nice and professional but the app unblocks the microphone by itself multiple times without me touching anything
Had this for years and always the same on every phone! Switches itself off to unprotected every 2 weeks. Also, it seeks to "record", additional to requested permissions. I believe the app deactivates my extra onboard mic blocking app, where that app remains active in the absence of Micro Guard (BTW Also, Norton Apps appear to deactivate microphone blocking apps). However, this is now totally uninstalled and held suspect by me.
