Micro Guard™ makes sure that no hacker or spy can listen on you. With just one single click, the integrated microphone of your Android™ smartphone will be completely protected. 

Prevent spying
Not only millions of users, but also the former FBI-chief tape over the webcam and microphones of their devices. 

With good reason: Everything and everybody is spied on! We know this since June 2013 when the first NSA documents were revealed by whistle-blower Snowden. Since then, increasingly threatening details are being constantly uncovered. But not only have hackers found solutions to misuse the microphones without a warning signal to the user.
Also, the latest malware is highly dangerous because it specifically targets control of the integrated microphone to listen on the users.

Hear nothing – For those who should not
With only one click, the protection is activated, and Micro Guard™ blocks and observes all programs and processes that try to access the microphone of your smartphone. Every attempted security breach will be reported with a signal.

While all accesses and warnings are conveniently protocolled in the log file, the intelligent Deep Detective™ detects even previously unknown attacks.

Deep Detective™: Against (un)known threats
With the Deep Detective™, we have created an intelligent and smart detective that observes all accesses to your device.

The protection module permanently controls which process or app currently attempts to access the microphone. Additionally, it reports known – and thanks to modern heuristic methods – also unknown attack attempts.

Every possibility to spy on you is proactively restricted from hackers, spies, and Trojans.

+ Microphone protection

Reviews From google play store

Hey DEVS! So I opted to purchase the 12 month deep detective plan and it worked GREAT... For about a week until today. I tapped on the thumbnail on my phone to open up this app, and it wouldn't even open. I forced stopped, cleared cache, everything normal. Then went to REopen it and it finally opened! But was EXTREMELY slow. When I started to type in my pin number my number(s) would remain highlighted and the app was VERY unresponsive. No number that I typed in would register. Please respond!

Developer doesn't seem to understand their product across the board. I've bought numerous apps from Protect Star trying to be supportive and everytime they update they want for me to repurchase. I strongly suggest you find an alternative to any Protect Star applications.

Absolutely love this app. Best investment ever! It's scary how many apps try to access my microphone. Thank you!!

This app is such a rip-off. Uninstalled. It keeps unexpectedly shutting off. And don't tell me to Restart my phone like you've been telling everyone else who left a Review having the same issue with this app. I Restarted my phone several times. Cleared the Cache. Made sure the App was whitelisted to run in the background and so it wouldn't be put to sleep. And this rip-off of an app still keeps unexpectedly shutting off with NO indication saying it was NOT protected. I want a refund.

I have been using this and the camera blocker for a couple years now and its so easy to use and it works near flawlessly. Only issues that have come up have been when I upgrade my Pixel to the latest OS but fixes were released shorlty after. Their support is also excellent with prompt responses and they will work with you until a solution is found. Couldnt recommend enough. Don't trust those copy-cat apps out there. These guys were the first.

I've used ProtectStar INC's applications for years and can honestly say they are a brilliant investment. I own all the PRO apps, but if you're on a budget they even let you use most of it free! Support is fast and always gets things fixed. Refunds if ever needed were always offered NO FUSS. Most low ratings are due to not understanding the setup and are quite unfair as they will help you sort it out painlessly. 10/10

I always have issues with their whitelist, I have Telegram on whitelist but only 2 of 5 Telegram calls goes through with microphone not blocked. I have sent email to support but no reply. I will update my feedback when they reply and fix the issue. Thank you for your reply. The device restart not help. As soon I will receive the patch I will update my feedback. August 2019: Problem not yet fixed...

the program shuts off without me knowing in the background. no indication. i just notice the icon says its not protected. i would just try to turn it back on and the quick button dosent work. i have to open the program an try to turn it back on. In the past that method didnt work so i uninstalled it then reinstalled and it worked again after. unfortunately now its doing it again .... this program is hacked in my opinion. pls fix this obvious security breach on your program.

Not working at all on redmi note 5 pro. cant block any prog. i tried both default and alternative mode. please check the issue and update. android 9 miui 10. Yes After restarting nothing changed

I find firewall is disabled after using this so cannot use. Stopped working won't active, i want my money back, no refund button is down, only bought couple hours ago.

Even I had turned on Accessibility option and chosen to block all apps, I can still record sound in Whatsapp manually(holding Whatsapp's mic icon). I am using an android 10 device.

Im not sure im that important that someone would record my conversaions but if they try, im glad i have this app. Thank you.

Thank you for your quick reply. It's all fixed now. Will return with a review in a week or so. Also, is there a way to remove the icon from my lock screen? Thank you.

I use both the Camera Guard Pro and Micro Guard Pro. They're not expensive to buy in my opinion, I just don't want to waste my time worrying about smartphone camera and microphone privacy issues. And I've had no issues whatsoever with battery usage, despite unchecking them as apps not being optimized. Basically, the app is excellent.

Again im letting you developers know this program keeps shutting down unexpectedly without my knowledge. And wont reactivate until i reset my phone or kill the program. What is the issue with this program. And why does it keep doing this??? This is my 3rd time requesting something be done about this.... fix this obvious weak link in your programming.

I'm not saying anything.... Without this app! This is completely AWESOME!!

I use this on all my android devices, but on my Honor 6X (model BLN-L21), it gets frequently flagged as consuming too much power, so I close it and reopen it. It runs Android 7 and EMUI 5.0.3 (it seems to be abandoned by Honor/Huawei. Any chance of a fix? Ta ta.

Simple to use and handy app to keep an eye on whats trying to access your Microphone.

Good but not have important function if you not buy.

One of the best. You won't regret it.


Update I hung in there with the app and so far so good. Now to really make Guard Pro apps POP ...add them together, give the user the ability to block EITHER or ALL wifi, data, mic, and cam connections under dashboard blocked app detail area and this would be Wonderfully Fantastic . Thank you for getting it together 👍

Five Star App

One of my top five favorite and necessary apps. Flawless, glitch-free performance. Tried others, but had problems. Incredibly relieved to discover this one. Definitely worth upgrading to the pro version. The whitelist is awesome! Best and quickest customer support response EVER! Thanks, Max !!

Works very well, and works with an Auto Call Recorder (mine on S8). Whitelist controls access for apps only I deem neccessary and blocks the rest. Of course DON'T FORGET to reciprocate permissions on relevant apps!! i.e. most important when trying to setup auto call recorders to work with mike protecters; recorders which are already very difficult to program and manage. I wonder how many of the adament whingers actually get the context of the whitelist red and green icons reversed... just sayin'.

Excellent App a must for any smart device


This developer is stellar ! He not only cares about his product , but he cares about his customers ! He answers any questions or problems you might have within minutes ! It doesn't get any better than this !!!

After last update this app went from ok to lousy.Now on reboot ive got a top screen banner thats impossible to remove or disable via any settings and haptic feedback i dont want.

Even my camera, instagram, etc has to whitelisted, still get blocked -_- shall i uninstall?

Not sure they get blocked... Sure im keeping free version?

After promised update in May it's still not updated and doesn't work Edit; update now has everything working. Perfect

Worse now. Wont reactavate after failure .App is still letting other apps to use microphone. This app is being overwritten. Several times a day I find it unactavated. Garbage... fix it

REVISION: Since the promised repair, it's even worse than before. Keeps shutting itself off. Pfffttt. FIRST FEEDBACK: Had been very happy with it, but lately I have to restart it several times every day. Keeps turning itself off. Same device as always (LG V20). Uninstalling.

Im confused as to a few things. One being the pro app doesnt work unless i download the free one. Thats understandable but i wasnt even aware there was a free one when i purchased the Pro version. Apps usually have a note to install Free before Pro. I installed the Free one and its trying to sale me the Pro. The free app has no idea i already own the Pro. Im seriously confused. Am i running your Pro version? All signs point to i am! Then whats this mystery app "Pro Version" the "Free Version" is trying to sale me? IDK! I uninstalled the "Free Version" out of fear and the "Pro Version" started acting out. My pjones system showed that it was running but i couldnt get it to turn on. 😨 Its really a good app and i can't wait untill all the bugs are worked out. Ill then give it five stars. I cant wait. Happy Days ProtectStar and ProtectStar users! ✌☺

It does exactly what it says. It definitely works. It's amazing to see how often the microphone gets turned on for. This app with the camera guard is the best way to secure your phone from listening in on you.

The app does exactly what it is meant to do, locks down unwanted Mic use. I love the white list feature. I feel that I have made my phone very secure! Side note: the developer is quick to answer all my inquiries. Usually within the hour I have a response from a real person! I highly recommend this and all their apps!

Finally! Finally a developer did it right. An app that has an easy, effective UI. An app that actually works(not just a false sense of security). An easy to use Whitelist option. AND a real-time monitor to show what apps are attempting to spy. Most effective is the Mic AND Camera guard together. 5.....freaking.....stars.

I loved this app. But can you explain while certain apps can still use the microphone even though its automatically block all apps? And sometimes the protection goes unprotected by its self.

Mic re-activates itself all the time, normally after apps updates. Useless for me!

Long story short, chatting with the heroic Max, who took a lot of time out of his Sunday to discuss my concerns (of which there were many), I was persuaded to uninstall the free version and try another app about which a large number of users' were complaining because it didn't automatically unblock for calls and they had to remember to do so themselves - which was exactly what I wanted for my own purposes. It didn't block my microphone when I called my phone at all! So I uninstalled it and bought the PRO version of Micro Guard. Why? Because the level of support above and beyond the call of duty offered by ProtectStar is the kind I have always offered myself and that means I trust that the Devs and Support REALLY know what they are doing - you HAVE to in order to care THAT much about the service as well as the product. So, I now have the Pro versions of both blockers (cam and mic). Well done, Maxi when you get tired of being a techie, you should start managing a Customer Service department - I'll buy whatever product it is, even if I don't need it, just to experience the quality service 😉

"Start on Boot" does not work.

Battery use has improved a lot.

Works well but needs more of an intuitive approach.

Great work. worth 3 dollars definately. Keep it up.

Great app and extremely prompt support!

I love it

Wanted to say I really like the app, but I must admit I have one big complaint. Yes, I do want to have the icon in the drop-down notification list, so that I can enable usage of the microphone or the camera when I want. But I really hate it when the Deep Detective keeps notifying me that it found an app that needed access and it's blocked it. I've already gone through on both apps (cam/micro) configuration and have turned off both of the on/off notification selectors. If it needs to update me, just put it in a log (which, admittedly, I mostly ignore). Only notify me when problems occur, NOT when it's doing is job. I only care when it finds problems. Of course, if turning off those two notifications should have stopped the notifications, then why are the notification still occurring? And if turning off those notifications is not meant to stop Deep Detective notification, then please add that feature cuz this s freaking annoying. It's probably the only way I'll give it more than three stars.

1. Toggling to enable it through the notification doesn't work. 2. No easy way to batch whitelist or blacklist apps. 3. Add an option, maybe in the 3 dot menu in the top right, to whitelist/blacklist all system apps. 4. Add an option to only show apps that have the microphone permission to make it easier for us to choose from the list of apps. 5. Add an option to whitelist notifications of user specified app(s) about it/them being able to use the microphone.

Absolutely outstanding! So fast to block the threat, alert me then back to protecting us. Their customer service is so quick to respond and help that this app developer has no equal. P.S. I don't work for them, just telling you exactly as I'm experiencing it.

App icons keep disappearing from the top of my phone. Makes me wonder what exactly is going on.

Whitelist has problems

Wonderful. It's awesome to find out how many apps are attempting to access your phone's microphone every day, every hour, every minute! You ask yourself why? What would this or that app even need my microphone for? That's exactly why you need this Appointment! Definitely go for the Pro version. It's only $2, you'll be extremely happy with it, I promise. I'm not affiliated with this app in any way at all. But, I did get hacked in December, 2016. It was horrific. Save yourself a lot of potential problems. Oh, there is a camera version too. It's so easy to click this on and off, there's also a white list. The app does run constantly, but I've checked, it barely registers on the garage. I don't think you would notice the battery useage if you didn't go looking for it. Again, why do these apps want your microphone? They are using your phone for illegal things, they are placing charges to your accounts! Yes, you check your bills carefully, I do too. But these criminals have all sorts of ways of doing such things that are un-noticeable. Call me crazy, paranoid whatever you want too. But, hackers are our there, why do you think apps like this exist???

On point! I feel very safe and less stressed when talking on my phone. Definitely know this app is blocking any intruders!!! Love it!!

Really like your apps. See my other review under your Camera Guard Blocker Free, which was updated to the Pro features from within the Free app. This microphone blocker seems to work just fine for me, seamlessly working in combination with anti-virus & anti-malware apps + other security apps, just as you said in your description. It's easy to turn on & off, and this all while I have over 150 apps installed. I'm using Android 5.1.1 Lollipop on my cell phone, which I'm almost using like a laptop. Some microphone blockers seem to block by muting, whereas others seem to take & release control of the microphone. I have another mic blocker that uses the former method, whereas I believe yours uses the latter. Maybe that's overkill, but after I was tried to be listened in on a while back, by a company I had a problem with which made incoming calls to me 3 to 4 times a day for at least 2 months resulting in my having to report them to the CFPB and the FTC, I became cautious. As long as they're not used at the same time it seems to be OK, but I seem to prefer your app. You seem to make good apps. Keep up the good work. As a former, but aging programmer (dinasour), I like to encourage good developers when I can. Thanks.

Great app, now the auto lock feature is there, with easy access to disable the block from the notifications. It would be nice if there was a way to combine both Camera and Mic blocking notations together, to take up less room. Maybe a standalone app that can control all protectstar apps from one interface?

Installed...never asked for admin permissions like sister app cameraguard...fired up 'fast notepad,' clicked on microphone, Google voice to text worked immediately like usual and it was unlogged by this app. This undermined my trust...so what else can't this app block? 3 stars for the effort so far (stars for your reputation, not my actual observations)...want 4 or 5? Please more upfront w/ this app's limitations so expectations can be set accordingly, or update it to actually block/log any microphone access from any app or service. (Currently running kitkat 4.4.4 on an older phone...no refund requested, I'd rather support ongoing development and hope it gets better)

Killing batt and slows device/ £∆√€ TH3 Rest...testing

App runs very well. Try it !!! I'll bet you'll be shocked at how many unauthorized attempts get blocked !!!


I love what this does for personal security. However, it is still using upwards of 40% of my daily battery.

While it can't block everything (certain system apps) from accessing the mic, it's a lot better than nothing. It also seems like these guys are professional, although looks can be deceiving. I guess time will tell, but until now, I haven't trusted any of the microphone blocking apps except this one (partly because they are highly recommended by many prestigious magazines, etc.).

You really need to optimize the battery usage. That app keeps phone awake and drains battery like crazy. I won't ask for refund, but disable until you improve the performance. Once I see that fixed I'll add more stars.

Must have app just because your privacy is your right. The setting is very easy to manage and gives you a clear idea if what apps are active in the background recording.

Just what everyone needs on their phones


This app had broken my OK Google input, and even after uninstallation I can't repeat it, without wiping my phone! At the top of all, I have used it no more than 10 hours, and no refund! Backup from that crappy trash! I red all possible Androids instruction, on who to repear you OK Google voice input, tried everything - no result! Then Wipe! OK Google works! 6-7 hours using the app - no refund! Run away from this app! Nexus Shamu on the latest original OTA Android ROM from 5th of July - still 7.1.1.

Microphone keeps unblocking about twice a day, I have to turn it back on manually. I've used every security feature to try and stop this. Also, The constant notifications are a pain in the AZ. Paid for the pro version and I'm very disappointed.
