Firewall WITHOUT ROOT. Host name/domain name filtering, simple interface, fine-grained access control and no suspicious permissions on the firewall app itself. 


NoRoot Firewall may not work on LTE because it NoRoot Firewall currently doesn't support IPv6. I'm working on the fix. 

NoRoot Firewall requires NO ROOT. It protects your personal information from being sent to the Internet. NoRoot firewall notifies you when an app is trying to access the Internet. All you need to do is just press Allow or Deny button.

NoRoot Firewall allows you to create filter rules based on IP address, host name or domain name. You can allow or deny only specific connections of an app. 


- No root required as the name NoRoot Firewall says.

- Fine-grained access control based on IP/host name/domain name.

- Simple interface. Easy to use.

- Minimal permissions. No location, No phone number.

This is the perfect solution if you want a firewall for android without root. It gives you a complete protection for your Android. NoRoot Firewall is like Drodwall for no root users.

App ChangeLog

App Screens

requires following permissions on your android device.

view network connections
Allows the app to view information about network connections such as which networks exist and are connected.

Allows access to the list of accounts in the Accounts Service.

full network access
Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.

run at startup
Allows the app to have itself started as soon as the system has finished booting. This can make it take longer to start the phone and allow the app to slow down the overall phone by always running.

    One of the best firewall programs--I wish this was available for Windows--but it does have two flaws: 1) if there's a lot of network activity, it becomes impossible to create a filter from a log entry, as new logs push the one you want off the page (needs an option to pause the logs); and 2) the order of the rules matter, but there's no way to reorganise them, so if you want to add a rule to the top of the list, you have to delete all the rules first (needs a way to move rules up and down)

    This fire wall is great and very easy to use. My only problem that is on my side of my phone is that someone on my phone in which I cannot remove always disables the fire wall app. I do not think there is any app that can correct this problem. My phone is always taken over before I get the chance to protect any unwanted traffic. They take over my sim card within minutes including the system of my phone this has been a serious problem for a long time. This app is amazing for my problem

    The auto boot doesn't work. My phone is set to restart at midnight every day. That means that the firewall doesn't restart until 7 am when I have to do it manually. My phone is unprotected for many hours. There's also days I may forget to restart the firewall. This makes NoRoot Firewall worthless!!!! What's the point of having a protection when it won't start, thus not protecting? Garbage!!!

    I have been using this thanks for the advertisement-free great software. There are more advance functions that I can think of, but for the simplicity the current functions are sufficient. One minor problem though, there are times the firewall crashed, probably caused by games' anti-firewall systems to make sure they can throw us ads, please see if there is a way to better protect your line of defense against them

    I'm a long time user of this app and I absolutely love it. However after installing it on my new phone I find I'm unable to browse the internet despite not blocking anything. If I exit this app I'm able to browse again. The NoRoot log shows that nothing is being blocked but obviously something is.

    Seriously the best tool i have ever used. I'm using it on a kindle fire hd to block the automatic updates and ended up also using it to block games from downloading and displaying ads. It gives me more control and monitoring of my device than i thought was possible on a non rooted device. Amazing and i love it. I'll soon be putting it on all my devices because it gives me full control of what apps get connection to the "outside world" lol

    This was an awesome program until I got a new phone with Android 10 on an LTE carrier. For those of you with the issue, NoRoot Firewall will not play nice with LTE or 5G most notabley T-Mobile. If you run into the issue, it will block EVERYTHING as in no internet until you disable it or uninstall. Instead of leaving negative feedback and making them give up, lets encourage them with positive feedback to figure out a solution for this wonderful miracle app. I tried many others this is the best

    Hey, everyone. This app is awesome! Right now, as im typing this review, NoRoot Firewall is helping me to isolate and remove THE WORST system attack programs that ive ever seen! Thank you, NoRoot Firewall, Developers. You have outdone yourselves with the hreat work that you have put into this application! Chris

    I m a long time user of this firewall app since 2014 and I m very disappointed with this version. I just installed it on my new galaxy m51. It doesn't work properly. It set it to allow whatsapp, brave browser and couple of other apps. But brave browser can't connect to the internet when the firewall is on even though I allowed it. I have never faced this issue before on other devices. Pls fix this problem

    Auto start won't work at all on my Samsung A20e running Android 10, possibly because there is no way to programmatically enable it from the GUI, as the app still offers. That may not work on Android 10. I've disabled battery optimization on this app but still fails to auto start. Please look into it!

  11. Smoochie-avatar



    It cant block domains the way I want, I tried every damn way using global and custom app filters, I can get the app to block a site, but it always need the ip address, it ignores the domain/dns address. And its either block all, or allow all, it ignores the "custom rules" totally! Therefore I had to block all, then whitelist all damn websites I visited instead of just allowing all connections but not the custom ones (the ones I wanted to block) 😅 3/5 since this app is free.

    Lots of apps that have been granted permission to connect to the internet are behaving in a wonky manner. They work for awhile and then they don't. Everything goes back to normal if I stop the firewall. Didn't use to be like that. Even Google Play has difficulties downloading apps despite given full access to the internet. Am using Samsung s10 and s20 with Android Ver 9 and Ver 10. Hope dev can fix these issues.

    So far, it seems to work great for blocking ads on apps. However, the VPN is so slow that it won't even load the play store, so it almost puts it into airplane mode. I need to rest of my messages still come through when it's on. Def turn it off when not using it. Also, the notifications are constant (I mean every constant) for apps I haven't blocked accessing network, until you turn them off in Android settings. I don't need to know what unblocked apps are doing every second. It works,.though.

    I have this app installed on all my Android devices. Many apps want more permissions than are necessary and this app allows me to restrict other apps from accessing the internet. I also look at the log pretty often to see which apps are trying to access the internet. Thank you very much for developing this app!

  15. Catalin-avatar



    Samsung S20 / Android 10. it seems that the application blocks some applications that have guaranteed internet access. Including the Yahoo Mail app, whatever I tried I couldn't make it work, I finally had to uninstall it. Unfortunately, I really liked the application but it seems to have some problems, then I noticed that it does not even activate itself after a restart and this problem was also in older versions.

    NoRoot Firewall often stops, and apps I would prefer to have permanently blocked then get access. Would love if they Implement a timer to turn the firewall back on when you temporarily want to shut it off. Also an app access timer that would grant temporary internet access to an app and then automatically shut off.

    It is one of the best firewall there is but nowadays it does has started showing few problems. It does not auto start and sometimes it stops working automatically. I never stopped it manually. It did not use to happen before. Could you fix it please?

    Love this app !! Great work from the developer. This app does what it promises and does it great. I have it with VPN settings tweaked so that mobile data would be turned off If VPN is off but the issue is playstore and other apps bypasses it!!. I think the problem is with the ROM itself and It seems fishy. This app doesn't asks for unnecessary permissions nor has any ads and It don't even asks your money in any way. The kind of professionalism and ethics the developers has made me really happy.

    Wow! Can't believe it! This app works Instant notification of app that wishes to use the internet and provides an option which allow or deny Only downside is, it should have option to block or allow all by the click of a button or icon also it provide another tab which displays blocked or allowed apps. They should also be a timeframe for allowing apps access the internet

    Functions perfectly for me, thanks for the tool. I have had no issues back then, but it'd be really interesting a menu to choose what apps to include as well to make my workflow smoother. I mean, it takes long minutes to setup the firewall and we better export all the filters properly, on the assumption of messing up the firewall rules. And I notice a cap of data sometimes and mismatching apps to filters, that means some core network function comes disabled by default. More customization please!

    Works well, but has a annoying bug. Every so often all internet access will be blocked until I stop and start the firewall. So I'll browse though ten or so webpages, then the next will refuse to loads until I restart the firewall.

    Nice app. But would be great if I could filter in coming /out going packets. For example- when I use a messaging app,I only want the message to go(the msg only get internet) and rest other should be block. The same when receiving msg.

    This used to always be the first app I installed on a new Android device or on an old one after a factory reset. It's great for finding out which apps are surreptitiously connecting to dodgy web servers and blocking those connections when they do. Unfortunately v4.0.2 seems to break wi-fi calling on my new Sony Xperia 10 II (Android 10). It still works great on my old Xperia XZ1c running Android 9, though. I hope NoRoot Firewall will get an update to fix this because it's an essential app.

    Useful app, but it does not work with the Smartthings app for me. No matter what I allow the Smartthings app indicates "No network connection". Once stopping the firewall, it works again. Too bad have to move to another app.

    Fantastic app. I use it to go offline on whatsapp while watching netflix. One suggestion though, please add "allow all" and "deny all" checkbox in the apps panel. It is tiresome to manually allow/deny each app. A home screen widget to turn it on/off would be a huge plus.

    Hey there 😊. I've been trying this app for a few days now and Works great! The only issue I found was after I've exported my filters to a .json file in my downloads folder, I can't seem to import them back. The file is there but greyed out. Please assist. Thanks!

    App does a decent job blocking Internet access to most apps, but seems to let apps that are blocked pass popup ads through. Apps like Facebook and Messager can still get Internet access even though they are blocked in this app. I wish this app could block specific addresses or ports. Firewall randomly shuts off giving blocked apps internet access. Should have an automatic restart option in case it gets turned off.

    Just got it. Well done. It shows how little control we have over the constant intrusion into our devices . Apps are run by people who have no respect for privacy. I hope Google and the other App developers don't find a way to cheat their way past this app. If they do litigation in the EU courts will be the only other option.

  31. G-avatar



    Very good app. It helps cutdown a ton of traffic I didn't know was happening until I installed this and started watching the logs. I would be happy to pay for this app if you could add an export feature for the logs. Good work so far. Thank you

    Works perfectly on Android 9 and after update still run no problem on Android 10. Being killed by overprotecting optimizer on my Redmi, but as it's set as Always-on VPN, so device remain secured. Would be fantastic, if one could configure it as a bridge or VPN client, so outgoing traffic would go through real VPN...

    Iv has issues with my phone in the past , and this app is ridiculous good .you can block all incoming root access and visibly watch as services and apps try gain access through root access .its the best app iv used and secured my phone at a time I was getting frustrated with no solution. You guys rock and the app is amazing .no root access works and u can access attempts live. Im your biggest fan

    Used to work, but just got an Android 10 phone and it doesn't auto start when set to and some apps which have been okayed don't access the internet, but do as soon as I stop the vpn. Probably going to give up on this soon.

    I give up, this was the greatest but now its blocking when its not suppose too. Come on fix the problem its blocking all apps and not many warnings. Example its blocking Amazon Shopping app, ive even tried setting the filters manually Android 10 Samsung galaxy S10 and s20 not working anymore. Still no fixvstill blocking things it should not, have you abandon the application?

    It's nice for the data control reason as i needed. But it suddenly created a problem such that without it being ON, on my phone, my whatsapp wont work. I noticed this when i unistalled it & whatsap stop. Even when i permitted all apps & then ununstall it, still my whatsapp in particular refusd to work except i install no rootfirewall back & give whatsapp access through it. So it's like the task killer of ur norootfirewall causd a permanent restriction so that my whatsapp works only with it. why?

    the new interface is great.. There should be a global checkbox which enables or disables all apps on apps page. there should be a search bar to quickly navigate to our app on apps page. Please do it.. I am eager to provide you 5 star :)

    I am increasing my rating because I went to the developer website & found comment about autostart not working on all phones and/or with draw-over apps.

    It will be great if there was a "favourites" section right at the top so that I do not have to scroll all the way to the bottom each time I want to open or close up Whatsapp (and the like) for the day. Make it with ten slots and then people can decide which ones they want right at the top. Really like this app otherwise, much more effective than the counterparts I've tried before venturing upon this one. A "favourites" section at the top, gets you 5 stars, c'mon guys!!!

    It worked great until the hackers I'm trying to block managed to disable the "Auto start on boot" option on the Home screen. Other than that, it works great and I highly recommend it...even if you're not under a hack attack.

    UNABLE TO IMPORT FILTERS ON ANDROID 6 or 9: I can EXPORT filters, but I found that I was unable to IMPORT them making the EXPORT function pointless. Seems READ permissions are missing. I can open Folders but ALL files are GREYED out. Was using an ALCATEL U5 (android 6), after Galaxy S4 died. Now have a Galaxy S8 (android 9) but the problem is still there. I have to retrain NoRoot Firewall from scratch for every app, which is tedious. Please FIX, if possible. MANY THANKS !!

    Overall The App is Excellent. I preferred This App over Similar apps like Netguard, Etc. But It needs some further improvements.. 1. Sorting Option is Required for View Whitelisted Apps & Blacklisted Apps Differently. 2. Design can Be More Stylish & Fluid. 3. There should be LockDown Mode for Completely Restrict Background Apps from Even Attempting to Use Internet & decrease Data Usage.

    Does exactly what it says. Super easy (but tedious) control over every single outgoing IP connection. LOTS of room to improve, but I use it every day as-is, it works perfectly well, and I haven't found anything as straightforward that could replace it. After you've set enough custom rules, you barely even notice it's there. Eventually, it just turns into "Let's see how many things this new app is going to try to connect to".

    Works great, would be nice though if the port numbers could be entered with a too and from range. Example: Ports 1 - 22. Rather than having to manually add a block for each individual port.

    This is perfect. No root makes life perfect. I love it. If I have to restore the phone to factory, make sure you install this first. After you install this, turn off wifi/data. Then block all that bloat that you dont wish to run. There will be some apps that you will have to allow, but you know what you install. Just review all downloads, then you will know what to block. This works, I really wish I had found this 50 years ago... Chuckle chuckle. Thumbs up.

    Probably the best VPN firewall which also stops Android system files from accessing the internet. I which continue to start no matter how many times you kill it. They're only been a few surprises when I found that the firewall had stopped working & it did not inform me nor did not even restart itself. Since this is probably the most important app on my phone, it needs 2 restart. Update. this used to be a good app, but now it just shuts off and lets everything access the internet. How sad!

    The app is crashing a lot. Several times throughout the day I notice the icon missing from the notification bar. I then have to launch NoRoot firewall again and start the app. Not once has it restarted on boot up, always manually. It's a shame as I've used this app for years but have had to switch to a different program. Once the issue is fixed I will return.

    I very much like this app, and have found it to be quite effective. However, if I could be granted one wish for an improvement, I would ask that in addition to the connectivity options, yes/no, the addition of the option, "Ask me every time". I realize what that could mean, but it would still be *very* useful for analysis and control! None the less, thank you for your fine work! :-)

    After a day it stopped working, and was blocking everything (even tough the apps were whitelisted). Also, other apps which were trying to connect weren't being picked up as Pending. I'm on Google Pixel 3a

    I bought this years ago and used it for a long time, it's a wonderfully designed app. Over the years and multiple phones I kinda forgot about it😬. I found it again and I absolutely love what the dev has done with it, very impressive and works so well that I'm very surprised All Mighty Google has not taken it down. I'll never forget you again NoRoot FireWall.

    Unable to use dropbox, onedrive or googledri e when the app is enabled. Not a complete loss since the app is mostly used to block ads but, given the increased reliance on remote accessing this is important.

    You might want to know that the "export filter" works, but not the "import filter" function. I have to re-set everything manually again, it simply does not import the file that I exported several moments ago. Please fix it. EDIT TO ADD::: THIS APP IS SUCKING MY BATTERY DRY TOO FAST!!

    I like what this application does it works fairly well except for one application that I use. But it's a very big battery used to be that Google services was my biggest battery user at around 8 to 10%.This firewall app is now the biggest with 57%. I can't afford to have an app use that much battery. So I'm forced to quit using it.

    I would like to start by saying this is a good firewall software, rather excellent one, but have been facing an errant problem since some time, especially after upgrade to Android 10. I have a xiaomi mi a3 phone, and autostart function of app doesnt work on it. Each time after reboot, i have to manually start noroot firewall, and this is becoming a problem. In this information driven age all apps are busy collecting my personal data. Can this be fixed on priority, please..

    This app is utter rubbish on my huawei p smart, continuously crashing, I practically have to switch it back on every now and then which makes it useless to have. Please improve on that. Might have to find another firewall app cause this is not working for me

    Blocked internet from all apps even the allowed apps like Chrome. Crashed almost immediately after blowing up the phone with connection alerts (including apps that were allowed internet) and then froze my phone up so I had to restart it. Had it less than 10min before I uninstalled.

    This app provides a solution to internet privacy that no other app can do. Even if you root your phone, you will want to use this firewall to filter out unwanted connections made by apps that you need to use (like Outlook connecting to Facebook). In terms of its functionality, it is straightforward & intuitive. I think that there is still room for this app to grow, such as preset firewall profiles, an external VPN service integration, and IP/domain identity lookup. support for IPv6 hopeful

    Everybody should use this app, you don't have a clue what your phone is doing before you get a firewall. I use it on my four smartphones. Ones is a cheap Chinese one and it is full of Spyware. I use it to read my Kobo and kindle books on when I am outside. It stopped tons of malicious apps. Use it for a week, month,... You will not regret it...

    Definitely helps control what apps can connect to which services/ports on the internet. Can be a little unstable, but generally recovers from crashes quite well. One observation; performing a network device scan/refresh in "Fing" *ALWAYS* crashes NoRoot for me. I suspect that NoRoot is crashing because of a stack or buffer overflow when trying to handle all the network packets being emitted by "Fing".

    wish it was updated frequently but it's ok, not a lot to update with such a minimalistic interface. got it right the first time.. if it ain't broke, don't fix it. right?! am I right?!yeah I'm right. but it would be nice if it had something like a DNS section that would further protect the apps that are allowed online.perhaps on filters page + a drop down bar allowing user to choose the DNS used for each app respectively? think of the whales mr greyshirts. If not for me, DO IT FOR THEM!!

    07 July: Auto-start stopped completely. 01 July: Auto-start has become iffy and the firewall stops randomly. -------- This works well. I can't be bothered rooting this phone, so this firewall is perfect. It's great for blocking bloatware access to the net. You can also block connections apps are making to facebook and google.

    I really loved this app when i used with note 9. But i changed to the LG V60 and it doesn't work anymore. 🙁some of the apps act as if i don't have a data connection and on others the app advises that they have internet access vs giving me the option to block or permit the access. Not sure why they both run the same andriod version. I imagine the problem is with the brand.

    Great app but just bought a Samsung S20+ & it blocks most apps & Web pages. Many apps cannot connect to the Internet (including Galaxy Store) even though access is allowed in NoRoot settings. If I turn off Noroot Firewall everything loads fine. Really disappointed as I really love this app on all my previous Galaxy Phones & still using on my Tablet. IPv6 has been around for years & Netguard (which I am reduced to using) worked fine with it & has for some time. Please Update NoRoot Firewall soon

    Doesn't work. Wanted to use this to block certain websites, but even after visiting the dev's website for troubleshooting it does nothing at all unless I apply filters for each app individually which is almost impossible to maintain. Good app if you want to completely turn off the internet for certain apps, though.

    I het so darn tired of programmers & software developer mscsrading VPN apps as Firewall apps! They are, or shoukd be, two different things. A Firewsll whould not rely on a VPN, but instead rely on policy settings, or real-time decisions of the administrator or orperator regarding each incomming or outgoing packet!!! This app is so minimalist that its not even a good VPN, and i can't see that it does anything that a Firewall should be doing. Very disappointing, and plan to delete ASAP.

    This app is actually a security threat: - it secretly sends some data in the background without our knowledge nor consent - it opens temporary backdoors - it does not send any notification about its own traffic so no one is aware it is trying to transmit, except for people who know where to look... Of course, the ports which are opened change frequently. You can verify those assertions for yourself with apps such as "network analyzer pro"/connections.

    I can't recommend no root firewall enough for your average Android user (even rooted phones). I use this app on every single one of my Android is rooted or not. One thing to keep in mind when you start this application it is creating a VPN tunnel in order to be able to allow or deny a specific traffic. So with this being said keep in mind everything you do while this application is started all the traffic in and out is going through a VPN server which we don't have control of. keep this in mind

    As a security professional, i find this app very useful. However, it has a few issues that need ironing out... it occasionally crashes, it doesnt like swithing from wifi to 3/4G and back of you turn them on/off. sometimes it doesnt work for no apparent reason even though its running, and the settings are in place. You also cannot run another vpn through it, which is a bit of a pain. That being said, a few upgrades time it will be a vital app for Android users.

  132. Penguin_Spy-avatar



    Great app. Provides all of the functionality I need and more, and with a user-friendly and nice looking UI. I have used this app for a significant ammount of time, across 2 phones, and it has worked flawlessly. Unfortunately, I have to uninstall it because it does not function on Android 10. The non-beta version does not allow any connections whatsoever, despite wifi and cellular avalible. I have tried the beta version, but I encountered a strange issue (see my review on that app).

  133. David Hendrie-avatar

    Having a firewall where you can decide which apps can connect to the internet is usually for those with root access. Rooting your device will invalidate its warranty, so is risky. I've been using this app for more than 2 years and it's prooved invaluable. The UI is simple, well laid out and easy to navigate. However, you need to check that it's running, especially after a restart or update. The "key" icon should show in the status bar to indicate that it's active.

    First off... awesome app. Thank you for providing it. But I can't ignore the stability issues. Sometimes all data flow seems to stop. I've found that it's due to NoRoot Firewall becoming unresponsive. Once I stop and restart the firewall, traffic resumes. That can take minutes, though, as NoRoot Firewall is apparently severely bogged down. I also find it frustrating that I can't (I assume) use a VPN service while running NoRoot Firewall. Aside from those issues... amazing app.

As long as the updates for this app continue to keep this app running the same as it does now, I will definitely change the rating that I gave to 5☆☆☆☆☆'s. Until then I am holding firmly at 4. As of yet with version dated at 3/30/19 is working as expected. Great work to the Devs.
