Introducing Micro Guard™ - the advanced microphone protection for your Android™ device. With a single click, activate powerful microphone protection and prevent any hacker, spy, or spyware from listening in on your conversations.

Prevent spying
Not only millions of users but also the former FBI chief tape over the webcam and microphones of their devices to take this precaution.

With good reason: Everything and everybody is spied on! Of course, we had known this since June 2013 when whistle-blower Snowden revealed the first NSA documents. Since then, increasingly threatening details have been constantly uncovered. But not only have hackers found solutions to misuse the integrated microphones of mobile devices without a warning signal to the user, but spyware is also highly dangerous because it specifically targets control of the built-in microphone to listen to the users.

Hear nothing – For those who should not
Our Micro Blocker feature effectively blocks all apps and processes that try to access your device's microphone, ensuring complete privacy and security. The intelligent Deep Detective™ feature goes even further by detecting previously unknown attacks and proactively restricting any possibility of surveillance.

Deep Detective™: A smart invention against (un)known threats
Deep Detective™ Live, our optional anti-spyware scanner, detects various fraudulent elements with thousands of attack signatures. In addition, its advanced heuristic methods make it a must-have for those concerned about microphone misuse. This feature is available through a subscription.

Combine Micro Guard™ with our Camera Guard™ app to protect your device's microphone and camera. Micro Guard™ also works seamlessly with other existing security solutions.
The free edition of Micro Guard™ includes features such as a microphone blocker, Deep Detective™ Lite, a logfile protocol, passcode protection, a Widget, dark mode, and a list of all apps with microphone access.

Ratings and reviews

Although it's an app with lots of good functions, there are still bugs. First of all, it interferes with the alarm clock application, causing the alarm to sound only a few seconds, instead of sounding until snoozed, or dismissed. Second of all, boot protection startup of the application does not disable microphone for "ok GOOGLE" function. If you turn the Mic Blocker off and turn it back on, it does prevent "Ok GOOGLE" from listening to the microphone.

Inconsistent and unreliable. Will often show as "on" (as in blocking mic) but mic will still be on, which can lead to some awkward or risky situations depending how you're using this. I use it to mute myself without using the mute function and people seem to still hear me sometimes. The widget also just doesn't work at all. And another dangerous bug is that it seems to block alarms, but like everything in this app, inconsistently so. Hard to depend on this at all. Poor experience overall.

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
