Description
Micro Guard™ is a microphone blocker & anti-spy app that helps prevent 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. When you don’t need the microphone, use Micro Guard to switch to Mic Off mode and reduce unwanted background access.
When protection is active, Micro Guard helps block microphone access on your device, records each access attempt in a logbook and alerts you to suspicious behavior — so you stay in control of your privacy.
Core microphone protection • 24/7 microphone blocker / mic lock: keep the microphone locked when you are not using it • Whitelist & access control: allow trusted apps and block unknown apps • One-tap Mic Off: quickly disable microphone access and re-enable it when needed (microphone disabler) • Deep Detective™ Lite: smart engine that monitors microphone access and helps detect unusual behavior • Logbook & alerts: detailed log of microphone access attempts plus notifications if something tries to listen in the background • Microphone permission list: quickly review which installed apps can use the mic • Passcode protection: secure the app so nobody can change your protection settings • Home screen widget & quick toggle: enable or disable microphone blocking 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 microphone 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 block the mic again 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 • Online meetings & video calls: reduce background recording risk • Journalists, lawyers, doctors, creators and business users who handle sensitive conversations • Travelers and people who use public Wi‑Fi or 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 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. 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 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 and protect your conversations from unwanted listening with Micro Guard.

Microphone Blocker & Guard does a Great job at blocking and Guarding my phone it works Very well and all the other Protect Star apps do a Great job as well ....
★★☆☆☆Trubl O'seven· May 10, 2024
App looks good, but when I was listening to Spanish music on the radio my phone asked me if I wanted to translate the page to Spanish which I have never done before, so I assume my phone or browser was still able to know I was listening to Spanish music so.....
★☆☆☆☆Helen and David Brown· Jan 9, 2025
Not as advertised. I was expecting the app to block my microphone, but it just does some weird scan to check for other apps that use the microphone. A bit pointless.
★☆☆☆☆Jude Walker· Feb 26, 2026
So I have to pay for this to even work on android 15+ from start up or even at all as I have it running and the green microphone icon showing me it's monitoring the mic is being turned off even with the app on and turned on and in the background within seconds it's disabled in front of me in the app??? So for ut it works at all we have to pay then, so there's no free versions of your apps at all and the camera guard Google and the police have blocked on any new android phones completely android14+
★☆☆☆☆Jeremy F· Apr 6, 2024
Hmm, even when selected to mute It let the video camera app record audio as it normally would.
