Privacy Policy

1. Product Information

This extension is called WebKB - Local Knowledge Clipper. WebKB is a local-first browser extension that helps users save, organize, and read web articles as a personal knowledge base.

2. Data Processed and Stored

WebKB only processes content when the user intentionally saves or previews a page, or uses an optional AI suggestion feature. The data may include:

• Web page title
• Original URL
• Author or website name
• Article summary
• Readable article content
• Category
• Tags
• AI-generated summary
• AI provider settings
• AI API key entered by the user
• Interface language and reader preferences

3. Where Data Is Stored

WebKB stores saved article files locally on the user's computer, typically under the WebKnowledgeBase folder in the user's Downloads directory.

WebKB also stores extension settings and library metadata in chrome.storage.local in the user's browser.

WebKB does not operate its own server to store users' saved articles, browsing history, API keys, or library data.

4. AI Data Transmission

AI features are optional. WebKB only sends article data to an AI provider when the user intentionally clicks an AI suggestion or translation-related action that requires such processing.

When AI suggestions are used, WebKB may send the article title, URL, summary, and part of the article content to the AI provider selected by the user in Settings. This is used to generate suggested categories, tags, and summaries.

Supported AI provider options may include DeepSeek, Gemini, OpenAI, OpenRouter, Ollama, Chrome Built-in AI / Translator, and custom OpenAI-compatible APIs, depending on the user's configuration.

Chrome Built-in AI / Translator features, when available, are processed through the browser's built-in capabilities. Ollama is intended for user-managed local or self-hosted AI usage.

The WebKB developer does not receive, proxy, log, or store AI request contents.

5. API Key Handling

• API keys are stored only in the user's local browser storage via chrome.storage.local.
• API keys are used only to call the AI provider configured by the user.
• API keys are not written to exported article files such as article.html, article.md, metadata.json, index.html, or articles.csv.
• API keys are not uploaded to WebKB developer servers.
• Users can remove or replace their API keys at any time in the extension settings or by clearing extension storage.

6. Developer Statements

• WebKB does not sell user data.
• WebKB does not share user data with data brokers.
• WebKB does not create a server-side database of users' browsing history.
• WebKB does not continuously read web pages in the background.
• WebKB processes the current page only after a user-initiated action.
• WebKB does not use remote code.

7. User Control

Users remain in control of their saved content and extension data. Users can:

• Delete article records from the WebKB Library.
• Manually delete the local WebKnowledgeBase folder.
• Remove or change AI provider settings and API keys.
• Clear the extension's browser storage.
• Uninstall the extension at any time.
