Where Data is Stored

All data is stored locally on your device using:

  • chrome.storage.local: For extension settings and encrypted API keys
We do not operate any servers - your data never leaves your device except when sent to AI providers.

Data Usage

How We Use Your Data

  1. API Keys: Used exclusively to authenticate with AI providers you choose
  2. Chat History: Stored locally for your reference and context management
  3. Personal Information: Used only for autofill features when you explicitly trigger them
  4. Page Context: Extracted only when you enable "Current Page" feature
  5. Settings: Applied to customize your experience

Third-Party Data Sharing

When you use AiLex, your data is sent directly from your browser to the AI providers you select:

  • OpenAI (api.openai.com)
  • Anthropic (api.anthropic.com)
  • Google Gemini (generativelanguage.googleapis.com)
  • OpenRouter (openrouter.ai)
  • X.AI/Grok (api.x.ai)
  • DeepSeek (api.deepseek.com)
  • LM Studio (localhost or custom endpoints)
Important: Each AI provider has its own privacy policy and data handling practices. Please review their policies:


We do not have access to, collect, or store any data you send to these providers.

Data Security

Security Measures

  1. API Key Encryption: All API keys are encrypted before storage using browser cryptography APIs
  2. Local Storage Only: No data is transmitted to our servers
  3. Secure Communication: All API requests use HTTPS
  4. No Analytics: We do not collect usage statistics or analytics

Your Control

You have complete control over your data:

  1. Export Settings: Export all your settings and data to a JSON file
  2. Delete Data:
    • Delete individual chats or messages
    • Clear all chat history
    • Remove personal information
    • Clear API logs
  3. Uninstall: Removing the extension deletes all locally stored data

Permissions

Why We Request Permissions

  • activeTab: To extract page context when you enable "Current Page" feature

Camera and Microphone

  • Camera: Accessed only when you explicitly use the webcam capture feature
  • Microphone: Accessed only when you explicitly use voice input
  • Both require explicit browser permission and can be revoked at any time

Data Breaches

Since all data is stored locally on your device and we operate no servers, there is no risk of a data breach from our infrastructure. Your data security depends on your device security and the security practices of the AI providers you choose to use.

  • Chrome Web Store Developer Program Policies

Remember: You are in control of your data. AiLex is designed with privacy-first principles, storing everything locally and giving you complete control over what data you share with AI providers.
