Net Blocker - Firewall per app 1.6.4

Net Blocker is a professional app that allows you to block specific apps from accessing the internet without the need for root access. Please read the following descriptions carefully before using.

As you may already know, there are apps and games that may access the internet for various purposes, such as displaying ads or stealing personal data. Some apps also continue to access the internet in the background even after you have exited them. To address such concerns, it is advisable to block certain apps from accessing the internet to achieve the following benefits:

• Reduce data usage
• Enhance privacy
• Prolong battery life

The app offers the following features:

• Safe and user-friendly
• No root access required
• No dangerous permissions required
• Compatible with Android 5.1 and higher

Please note the following:

• This app only sets up a local VPN interface to block network traffic of apps without requiring root access. It does not request dangerous permissions, such as location, contacts, SMS, or storage. Therefore, you can rest assured that it does not connect to remote servers to steal your privacy data.
• Since this app is based on the VPN framework of Android OS, you won't be able to use another VPN app simultaneously when it is turned on, and it may consume additional battery power.
• Even when apps and games are blocked from accessing the internet, they may still display ads loaded from cached memory. Clearing their cache will help hide these ads.
• Some instant messaging apps (such as WhatsApp and Skype) may rely on Google Play services to receive incoming messages when the app has no network connection. Blocking "Google Play services" may be necessary to prevent receiving messages in such apps.
• The battery optimization feature of Android OS may automatically disconnect VPN apps during sleep mode to save battery. You may need to add the Net Blocker app to the whitelist of the battery optimization settings to keep it functioning.
• This app cannot block Dual Messenger apps, as Dual Messenger is a feature exclusive to Samsung devices and does not fully support VPN functionality.

FAQ:

• Why am I unable to press the "OK" button on the dialog?

• This issue may occur if you are using an app that overlays other apps, such as blue light filter apps. These apps may overlay the VPN dialog, preventing you from pressing the "OK" button. This is a known bug in Android OS that can only be resolved through an OS update by Google. If your device has not received a fix yet, you may need to disable the light filter app temporarily and try again.
