Privacy Policy — LocalEngine
Last updated: September 2026
This Privacy Policy describes how LocalEngine ("the App") handles information when you use the LocalEngine applications for Mac, Windows, iPhone, and iPad. The App is designed with privacy in mind: we do not collect, transmit, or sell your personal data. Inference and your model files never leave your device.
1. User Data Collection
LocalEngine does NOT collect, harvest, or transmit any personal or sensitive user data.
Specifically, the app does not collect:
- Personal identifiers (name, email, account details)
- Chat prompts, transcripts, or text you send to local models
- Your model files (GGUF weights) or their contents
- Your device's location data (no location permissions are requested)
- Usage statistics, user behavior tracking, or telemetry
- Crash reports or system logs
2. User Data Handling
All model loading, chat, generation, and translation operations are processed locally on your device:
- Local Inference: Models are loaded and run locally on the device where LocalEngine is installed. The native Mac, Windows, iPhone, and iPad apps do not use cloud inference engines or contact external servers for generation.
- Local API (where available): The optional HTTP API
binds to loopback only (by default at
http://127.0.0.1:8765). It is opt-in and is not enabled by default. When enabled, requests from compatible apps or browser extensions are served entirely on-device. - Model Downloads: If you choose to download a model from the in-app catalog, the app fetches the GGUF file directly from its source so it can run locally. No prompts, transcripts, or personal data are sent as part of these downloads.
- File System Access: The app reads and writes files only when you explicitly import models or use import/export features. Any access is subject to the permissions provided by your platform.
3. User Data Storage
All models, transcripts, and settings are saved strictly on your local storage:
- Models & Settings: Your imported models, download jobs, chat history, and preferences are saved locally on the device where you use the app.
- API Tokens: If you configure a token for the local API, it is stored using the platform's secure credential storage and is never written to disk in plain text.
This data remains fully under your control. You can delete it at any time by removing individual models or transcripts in the app or uninstalling the app, subject to your platform's data-retention settings.
4. User Data Sharing
We do not share, sell, or disclose your data to anyone. Since LocalEngine does not collect any of your information or host any remote backend servers, it is technically impossible for us to share or disclose your data with third parties.
