VCVA Local

A privacy-first Android app skeleton for local voice activation and voice-controlled actions without cloud processing, ads, telemetry, or account requirements.

Project goals

• Zero anti-features
• No internet dependency at runtime
• No analytics, trackers, or remote crash reporting
• Local speech recognition and command handling only
• dB-threshold activated local recorder as the core trigger mechanism
• FOSS-first build chain using open-source Android components and OS APIs

FOSS building blocks

This project is intentionally built from open-source upstream components and local Android system functionality:

• Kotlin: https://github.com/JetBrains/kotlin
• AndroidX: https://github.com/androidx/androidx
• Material Components for Android: https://github.com/material-components/material-components-android
• Android Open Source Project (AOSP): https://source.android.com/
• Android SpeechRecognizer framework APIs: https://source.android.com/docs/core/permissions/audio

The app does not include:

• Firebase
• AdMob
• Google Analytics
• proprietary STT backends
• cloud voice APIs
• account/login services
• crash reporting SDKs

Local-first design

• Microphone permission is requested only when needed.
• A dB threshold detector listens to ambient audio and triggers recording when sound exceeds the configured level.
• Speech recognition uses Android system speech APIs, running locally on the device.
• Recording files are stored locally on-device and never uploaded.
• All command handling stays on-device.
• The app remains usable offline.

Recommended repo-based architecture

1. Keep the app logic and UI in this project.
2. Use AndroidX and Material from their official GitHub repos.
3. Use Android framework speech APIs for local recognition.
4. Build all custom trigger logic in-house with local-only code paths.
5. Avoid any non-free or proprietary dependencies from the start.

Build

1. Install Android Studio.
2. Open this folder as an Android project.
3. Let Gradle sync.
4. Build a debug or release APK.

Anti-feature checklist

• No ads
• No analytics
• No account system
• No cloud processing
• No telemetry
• No trackers
• No mandatory internet access
• No paid upsells or proprietary licensing

Notes

This is a practical starter project for a voice-controlled voice-activated app with a dB-threshold activated recorder as the central feature. It stays completely local and auditable, and is designed as an open, ethical, privacy-preserving foundation for offline voice capture and local trigger logic without compromising user independence.
