Privacy Policy
Last Updated: July 21, 2026
1. Introduction
Thank you for using Lingyi (hereinafter referred to as "this Extension"). This Privacy Policy explains how we collect, use, store, and protect your data.
Lingyi is a browser-based AI translation extension. All data processing occurs entirely within your local browser. We operate no servers of our own and do not collect or upload any of your data.
2. Data Collection & Storage
2.1 Data We Collect
This Extension does not send any data to any remote server (except as described in the "Third-Party Services" section below). All data is stored locally in your browser:
| Data Type | Storage Location | Description |
|---|
| Configuration | browser.storage.local | Language preferences, translation modes, UI settings, etc. |
| API Keys | browser.storage.local | API keys for third-party AI service providers you configure |
| Translation Cache | IndexedDB | Local cache of translated content to speed up repeated translations |
| Text to Translate | Memory (temporary) | Text you select or is automatically identified for translation on web pages |
2.2 Data We Do Not Collect
- ❌ Your browsing history
- ❌ Your IP address
- ❌ Your device information
- ❌ Your geographic location
- ❌ Your personal information (name, email, etc.)
- ❌ Any telemetry or analytics data
3. API Key Management
Lingyi allows you to configure your own API keys for AI service providers (such as Anthropic, OpenAI, Google, etc.).
- Local Storage: API keys are stored exclusively in your browser's
storage.local
- No Exposure: API keys are never exposed in the DOM, message passing, or any UI
- Provider-Only Transmission: API keys are sent only to the corresponding service provider's API endpoint when making requests; they are never forwarded to any third party
- Secure Execution: All API calls are executed in the Background Service Worker, preventing exposure in the web page context
4. Third-Party Services
While Lingyi itself does not collect data, when you use the translation feature, the text to be translated is sent to your configured AI service provider.
4.1 Supported Providers
Lingyi supports 32+ AI service providers via the Vercel AI SDK, including but not limited to:
- Anthropic (Claude)
- OpenAI (GPT)
- Google (Gemini)
- Azure OpenAI
- Ollama (self-hosted)
- Other user-configured providers
4.2 Data Transmission
- Text to be translated is sent directly from your browser to the API endpoint of your chosen provider
- All transmissions are encrypted via HTTPS
- Each provider's data handling practices are governed by that provider's own policies; please refer to their respective privacy policies
4.3 Local Deployment Option
If you use a self-hosted solution such as Ollama, translation data will never leave your device, providing the highest level of privacy protection.
5. Data Sharing & Disclosure
- No Sharing: We do not sell, rent, or otherwise share your data with any third party
- No Ads: This Extension contains no advertisements or tracking code
- No Analytics: This Extension does not integrate any data analytics services (e.g., Google Analytics)
- Legal Requirements: Since we do not hold any of your data, there is no data to disclose under legal requirements
6. Data Security
- Local First: All sensitive data (such as API keys) is stored in the browser's encrypted storage
- Sandbox Isolation: Content scripts are fully isolated using Shadow DOM, preventing interference with the web page environment
- Minimal Permissions: This Extension requests only the minimum permissions necessary to implement translation functionality
- No Remote Code: No executable code is loaded from external sources
7. Data Deletion
You can delete all data generated by this Extension at any time through the following methods:
- Uninstall the Extension: Uninstall Lingyi from your browser's extension management page; all local data will be automatically cleared
- Manual Clearance: Clear the translation cache from the Extension's settings page
- Browser Data Management: Use your browser's "Clear browsing data" feature to clear data stored by the Extension
8. Protection of Minors
This Extension is intended for users of all ages. Since this Extension does not collect any personal data, no special protection for minors is required.
9. Changes to This Privacy Policy
- If this Privacy Policy is updated, it will be published on this page with the "Last Updated" date revised
