Halanoi

Halanoi Sovereign is a professional-grade, open-source focus lockdown utility for Android. By utilizing Device Owner administrative privileges (similar to corporate IT policies) combined with a local Edge AI Screen Sniper, Halanoi makes it virtually impossible to bypass your focus session or sneak past your study blocks.

Kea features:

1. Local AI Vision & Text Sniper

• Powered by a 64MB local TFLite transformer model running offline on-device.
• Scrapes active text, search queries, inputs, and browser URL bars in real-time.
• Classifies content into harmful/distracting categories or custom keywords.
• If classified above the confidence threshold, it instantly redirects the browser to http://127.0.0.1, hits Home, and locks the screen.

2. Browser Lockdown Shield

• Standard Mode: Allows Google Chrome, but permanently blocks and hides all other alternative browsers to prevent bypasses.
• Chrome-Only Mode: Disables and hides all browsers on the phone except Google Chrome.
• Zero-Browser Mode: Completely disables and hides all web browsers for a total web blackout.
• Active Store Scanner: Runs background scans while you browse the Google Play Store, Vivo App Store, or package installers. It automatically detects and hides new browsers the moment they are installed.
• Hydra Auto-Hide: If an unauthorized browser is opened, it is instantly hidden and killed via the OS, removing its launcher icon.

3. AI Dataset & Evaluation Lab (ML Ground Truth Studio)

• Live Inference Telemetry: Captures real-time screen scraping events (scraped text, predicted category, confidence score, and timestamp) directly into a local SQLite database.
• Interactive Ground-Truth Tagging: Rate live inferences on the fly: Correct, False Positive (over-blocked safe content), or False Negative (missed distraction).
• Live Accuracy & Metrics Dashboard: Real-time calculation of model precision, false positive rates, and deflection accuracy.
• 1-Tap Dataset Exporter: Export collected mobile telemetry into standardized RFC 4180 CSV (for Pandas/Excel/Jupyter) or JSON for fine-tuning.
• Model Training Pipeline: Visit the companion repository kavinmaranravi/Halanoi_AI to access the complete dataset, PyTorch/TensorFlow training scripts, and model quantization pipeline used to build the on-device TFLite models!

4. OS-Level Device Owner Lockdown (God Mode)

• Anti-Uninstall Guard: Prevents the app from being uninstalled.
• Anti-Clear-Data Guard: Greys out "Force Stop" and "Clear Data" inside the Android App Info settings.
• Settings Freeze: Locks the Accessibility Settings menu so the Accessibility Service cannot be disabled.
• Anti-Factory-Reset Guard: Greys out the factory reset settings to prevent bypassing blocks by wiping the device.
• VPN Lockdown: Prevents turning off or modifying the local VPN Network Shield.
• Sideloading Guard: Revokes permission to install unknown apps, blocking manual APK installations from WhatsApp, Chrome downloads, or File Managers.
