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.

Features "Free Edition":
+ Microphone blocker 24/7
+ Deep Detective™
+ Logfile protocol
+ Passcode protection
+ Widget
+ Dark Mode

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 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.
