NetGenix — Data Usage & App Firewall

NetGenix is a privacy-first data-monitoring and firewall app for Android, built natively in Kotlin. It gives everyday users a clear, no-jargon view of which apps are eating their mobile data — and the power to block any app's internet instantly.

The app is built around two simple ideas: see where your data goes, and take control of it. It reads Android's own usage statistics (no account, no server, no data collection) to break down data consumption per app, split between Wi-Fi and mobile. When you want to stop an app from using the internet — a background data hog, a game, or an app you simply don't trust — one tap cuts it off, while every other app keeps working normally.

NetGenix runs entirely on-device. There is no cloud, no tracking, and no ads. The firewall uses a local VPN that activates only when you actually block something, so it never interferes with your normal connection. The interface is fully bilingual (Hindi and English, auto-detected), designed to be genuinely usable by non-technical people.

Key features:

• Per-app data usage — Wi-Fi and mobile data for each app, over today, 7 days, or 30 days.

• One-tap app firewall — block any app's internet; other apps stay unaffected.

• Data limit alerts — set a monthly mobile-data limit and get warned at 80% and 100%.

• Night block — automatically cut internet for apps between 12am–6am.

• Start on boot — monitoring and rules resume after a restart.

• Bilingual — complete Hindi and English interface.

• Fully offline & private — nothing leaves the device, ever.

Engineered to stay lightweight and reliable — the app is around 400 KB, with no bloat, no ads, and no third-party trackers of its own.
