About this App
Microphone blocker & microphone disabler: mic off + anti-spyware protection.
Micro Guard™ is a microphone blocker & anti-spy app that helps stop apps and spyware from listening through your Android device’s microphone.
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.
