App that control which apps can use 3g/edge and wifi

Is there any app that can control which apps are allowed to use 3g/edge to connect to the Internet and which are only allowed to do that when wifi is available?
Yes me too want to know how to restrict data download.
Thank you.
IMO, an app that manages all permissions would be even better. I haven't heard of any such apps but hopefully someone can come up with something.
can I somehow restrict all data transfers? I have no data tarif from my mobile operator and allmost everywhere I am i have free wifi connection (so I want use wifi).
Thank you
"Tasker" may be able to help, it can control your settings based on all kinds of scenarios. I have my mobile data disabled and use Tasker to enable it when certain apps start (internet, email, etc), it will disable it automatically when you close that app (needs apndroid installed). I do the same with GPS.
Tasker gives you loads of options and control, you can create custom widgets and automatic profile switching.

droidwall may be of interest to you guys, it blocks all apps to connect to 3g/edge unless you specify the app in the droidwall whitelist
note: Droidwall does require root
Would appreciate to know where to get the "Tasker" you mentioned.
Thank you.
I can find Tasker in the market, but I first found it on androlib. I use it to disable ´mobile data' during the night.

How to monitor network data details?

Is there a way to monitor an app's internet data traffic? I am specifically interested in which webservice (URL) an app is calling, and what data is passed to it from my device. I have found some network monitor apps on google play that tells you the URL, but not the details of what data is passed, rendering it not useful.
thanks,
Joe
you mean somthing like wireshark or tcpdump?
if you want to capture packets you can use "shark for root" (you can use it only if you have a root).
Google network sniffer

How Can I Block Internet Access (rooted)?

I have a rooted Note 3, TMobile, n900t. Any ideas on how I could block access to the Internet, as well as access to Google Play, but have my downloaded apps, such as gmail, still function? I've recently joined a Sexaholic Anonymous due to my porn addiction and need some safeguards in place in order to continue using this phone. I realize when there's a will, there's a way, I just want that way to be as near impossible to access. Possibly even something that would block access via password someone else enters.
Thank you for your help.
Hey , Use Android Firewall+ from Playstore :good:
As far as internet access blocking goes , AFwall+ will get stuff done for you.
For additional app security and locking with password / pin , try AppLock
* Both apps free from playstore

Internet usage, block it except local LAN

Hi
I'm wondering if it possible to block the NSTV from using the internet if I not want it to. It looks like it uses much data I background that I can't find.
Is it a way to block it, but still have access to my LAN?
And a simple way to turn it on or off?
I use cable, no WiFi to my router.
Petter
Can't you either;-
Block access by device on your router
Or
Give the Shield a static IP address with no gateway / the wrong gateway
That can be an option. But it's not an easy way to manage.
Is there an way to code or an app that can change these network settings?
(So it's get a little bit easier to change it)
Asks again.
Is there an app for this now?
Tried an app for this that's made for phone, but that app was not usable for NSTV.
Don't remember the app name, but found in xda.

Is there a way to force user use Always on VPN connection on 6T phone?

Hi friends, i try to secure my children phones from accessing not wonted sites. At home i configured mikrotik router so there is no way to bypass restrictions. But i cannot control what they access from mobile network.
The ideal way would be to connect phone to home VPN . Is there a way to force phone use VPN so user could not just switch it off?
In that case all home network rules and restrictions would work.
If you have some ideas about it, please share.
P.S. I did it recently when noticed that 8 year old neighbor children are watching porn...
I never tried it, but you could check if "Multiple users" gives you the chance to create a low privileged user which could maybe not edit network/vpn/dns settings?
Maybe you could setup the main accounts &co from the admin user and secure it with your fingerprint, then grant your childs just the "guest" user access?
Maybe give it a try and check what those users (a new one you create or the guest one) are allowed to do and if that achieves your objective

My mother utilized Norton Family to limit what could be seen and not seen. You can also utilize the built in family link ability from google to block searches on google and app store. Link for reference: https://protectyoungeyes.com/content/android-parental-controls-complete-guide-parents/
As far as what you are asking, you could use adguard to create the persistent VPN and use their family dns set up. Once done you can always use an app locker to lock the app settings and the app itself so it can't be uninstalled.
maybe you can test an app locker. with it, they can't stop the app vpn if they haven't the code lock

You can use an APP locker to lock the settings.
If you can't access the settings you can't turn it off.

Try private dns: dns-family.adguard.com

One problem with the "lock the VPN settings" is that the VPN swithes off fairly randomly. On my phone, I set up a VPN using my home router, and connect to it while on mobile. But at random points in the day it disconnects. It's necessary to go back into VPN settings to turn it back on...

I already use opendns, it blocks everything.
I do not see option to add just dns in android. Child just installs some vpn app or connects to some wifi and restrictions does not work.
On other hand if phone is connected to home vpn, there is no way to bypass it.
My microtik bloks all proxy, vpn and routes dns to opendns.
thanks for app locker suggestion. will try it

It's under Wi-Fi and internet setting but only available for Android 9 version. The adguard family dns blocks ad and adult stuff also.
