# ESH Developers (ESHUB) > Sovereign Edge Computing, Hardware Telemetry, Offline Artificial Intelligence, and Zero-Knowledge Privacy Utilities for Android. ESH Developers is an independent systems engineering studio dedicated to building high-performance mobile applications that operate 100% on-device. We engineer sovereign utilities that refuse cloud telemetry, preserve battery longevity, protect user data via military-grade encryption, and execute neural intelligence completely offline. ## Core Products & Documentation - [Battery Drain (Battery Speed)](https://eshhub.com/battery-speed.html): High-frequency real-time battery discharge telemetry, millisecond-precision mA sensor monitoring, thermal throttling diagnostic suite, and battery health tracking without background CPU overhead. - [Battery Pro](https://eshhub.com/battery-pro.html): Enterprise-grade power analytics with 24-hour discharge heatmaps, emergency power reserve lock, customizable charge threshold alarms (80% stop notifications), and deep historical battery degradation metrics. - [Offline AI: MindSync](https://eshhub.com/offline-ai.html): 100% on-device neural writing and reasoning assistant. Runs local 4-bit quantized language models directly on mobile NPU/GPU/CPU with zero latency, zero cloud dependency, and total confidentiality. - [Privacy Vault](https://eshhub.com/privacy-vault.html): Zero-knowledge encrypted locker securing photos, videos, audio, and private notes with AES-256-GCM encryption, biometric authentication, intruder selfie detection, and rapid panic wipe triggers. - [GameForgeX](https://eshhub.com/gameforgex.html): Floating in-game performance overlay displaying real-time FPS, CPU/GPU thermal load, RAM turbo cleaner, and network jitter stabilizer designed for competitive mobile gamers. ## Company & Philosophy - [About ESH Developers](https://eshhub.com/about-us.html): Studio mission, architectural manifesto, edge-native compute paradigms, and team info based in Sri Lanka. - [Privacy Policy](https://eshhub.com/privacy_policy.html): Zero-telemetry declaration. No trackers, no ad-network SDKs, no remote server logging, and no sale of user data. - [Developer Hub on Google Play](https://play.google.com/store/apps/developer?id=ESH+developers): Official distribution portal for ESH Developers Android applications. ## Technical Specifications - Architecture: Pure on-device execution (Edge Computing) - Cryptography: AES-256-GCM with hardware-backed Android Keystore - Battery Telemetry: Kernel-level sysfs and BatteryManager polling at sub-second intervals - AI Runtime: Quantized ONNX / GGUF local model execution on Android NNAPI - Contact & Support: admin@eshhub.com / eash.feedback@gmail.com For full technical specifications and deep architectural documentation, see [llms-full.txt](https://eshhub.com/llms-full.txt).
