## Description

**Net Blocker - Firewall per app** is a simple and safe Android extension that empowers users to block internet access for specific applications without needing root access. It uses a local VPN interface to efficiently control network traffic on a per-app basis while maintaining privacy — no dangerous permissions like Location or Contacts are required.

Ideal for reducing data usage and enhancing privacy, Net Blocker helps prevent apps and games from loading unwanted ads or transmitting your data in the background. Its straightforward interface supports Android 5.1 and up, ensuring ease of use while highlighting important considerations such as disabling battery optimization and limitations with Samsung's Dual Messenger feature. Users can trust that the tool does not connect to remote servers, prioritizing security and user control.

Experience better privacy and data management on your Android device with Net Blocker, an essential firewall tool designed for per-app internet blocking without compromise.
