Support

What devices are supported?

Android 8.1+ (API 27). Full NPU acceleration requires Snapdragon 8 Gen 2 or newer. The app runs on all Android devices using GGUF CPU fallback models for non-Snapdragon hardware.

How much storage do AI models need?

Models range from ~50 MB (PaddleOCR) to ~2.5 GB (OmniNeural-4B VLM). You choose which models to download. No models are bundled with the APK.

Is my data safe?

All processing is local. No data is transmitted to any server. Android file-based encryption protects data at rest. Uninstall or clear app data to delete everything. See the Privacy Policy.

The app crashes when loading NPU models.

NPU models require Qualcomm Snapdragon. If your device uses a Google Tensor, Samsung Exynos, or MediaTek chip, select GGUF CPU models from the model list instead.

Can I export my health records?

Health records are stored as Markdown files in the app's internal storage directory. You can browse and edit them in-app. Full export functionality is planned for a future release.

Where are models downloaded from?

Models are fetched from huggingface.co/NexaAI. No personal data is sent during the download — only standard HTTP requests for the model files.
