Shieldu - Network Firewall

Are you concerned about online privacy, and what information some of your apps might be collecting and sending back home? Do you want to restrict Internet access for some pre-installed vendor apps that can't be disabled in your device settings?

Internet access is a core permission in android that can't be revoked by the user. This allows all kinds of analytics, and other forms of data collection and tracking by your installed apps to occur, of which you have very little control over.

Shieldu is an easy-to-use background service that aims to "shield you" against privacy leaks and malware that are an ever-present threat in our modern, connected lives. Any user-installed or pre-installed application or service on your device can be individually denied access to your Internet connection. Shieldu intercepts and discards network packets on both WiFi and Mobile connections for only the apps that you choose, ensuring their data never leaves your device.

Key Features

• Simple and intuitive interface

• Shows only apps with Internet permission

• Can block both user-installed and system apps

• Can auto-start in the background after device reboot

• Blocks both IPv4 and IPv6 network protocols

• Does not connect to any remote servers

• Has no tracking or analytics features

• Delivers no advertising or other payloads

• Requires no suspicious permissions

• Does not require root access

Important Notes

1. Shieldu is NOT an ad blocker. Advertisements and push notifications are generally delivered to individual applications through Google Play Services and other platform or third-party framework components.

2. Shieldu utilises the local VPN interface on your android device to intercept and drop network packets. As android only allows one application to use the VPN service at any time, Shieldu is not able to operate concurrently with another app that also requires access to the local VPN interface.

3. Some android devices restrict tethering and VPN services working concurrently. You may need to turn off active shielding in Shieldu while using your device as a mobile hotspot.

您是否关注在线隐私，以及您的某些应用可能收集和发送回家的哪些信息？是否要限制在设备设置中无法禁用的某些预安装供应商应用的Internet访问？

Internet访问是android中的核心权限，用户无法撤销。这允许您安装的应用程序进行各种分析以及其他形式的数据收集和跟踪，而您几乎无法控制。

Shieldu是一种易于使用的后台服务，旨在“保护您”免受隐私泄露和恶意软件的侵害，这些恶意软件是我们现代互联生活中永远存在的威胁。您设备上的任何用户安装或预安装的应用程序或服务都可以被单独拒绝访问您的Internet连接。 Shieldu仅在您选择的应用程序中拦截并丢弃WiFi和移动连接上的网络数据包，确保其数据永远不会离开您的设备。

重要说明

1. Shieldu不是广告拦截器。广告和推送通知通常通过Google Play服务和其他平台或第三方框架组件提供给各个应用程序。

2. Shieldu利用Android设备上的本地VPN接口拦截和丢弃网络数据包。由于android只允许一个应用程序随时使用VPN服务，因此Shieldu无法与另一个同时需要访问本地VPN接口的应用程序同时运行。

3.一些Android设备限制网络共享和VPN服务同时工作。在将设备用作移动热点时，您可能需要关闭Shieldu中的有源屏蔽。
