Privacy Policy

Last updated: January 2026

Summary: This extension stores all data locally on your device. The only time data leaves your device is when you request an AI explanation, which sends your selected text to the AI provider (OpenAI or Anthropic) using your own API key. We do not operate any servers or collect any data.

1. Information We Collect

This extension collects and stores the following information locally on your device only:

  • API keys: Your OpenAI or Anthropic API key that you manually enter
  • Selected text: Text you highlight on webpages when requesting explanations
  • Saved highlights: AI explanations you choose to save, along with any notes, tags, or folder assignments you add
  • Extension preferences: Your settings and folder configurations

We do not collect: Personal information, browsing history, cookies, IP addresses, device identifiers, or any analytics data.

2. How We Use Your Information

Your information is used solely to provide the extension's functionality:

  • API keys: Used to authenticate requests to your chosen AI provider (OpenAI or Anthropic)
  • Selected text: Sent to the AI provider to generate explanations
  • Saved highlights: Displayed in your personal library for future reference

We do not use your data for advertising, profiling, or any purpose other than providing the core extension functionality.

3. How We Store Your Information

All data is stored locally on your device using Chrome's built-in storage API (chrome.storage.local and chrome.storage.sync).

  • Storage location: Your browser's local storage, on your device only

We do not operate any servers. No data is transmitted to or stored on any servers controlled by us.

4. How We Share Your Information

We do not share your data with any third parties.

The only data transmission that occurs is when you request an AI explanation:

  • Your selected text and surrounding context is sent directly from your browser to OpenAI (api.openai.com) or Anthropic (api.anthropic.com), depending on your configuration
  • This transmission uses your own API key and occurs directly between your browser and the AI provider
  • We have no access to, and do not intercept, log, or store this data

Please review OpenAI's Privacy Policy or Anthropic's Privacy Policy for how they handle data you send to them.

5. Data Retention
