Privacy Policy
Last updated: February 22, 2026
Overview
Section titled “Overview”Context Bro is a browser extension that helps you share web page context with AI agents. Your privacy is central to its design — the extension follows an allowlist-first, share-nothing-by-default model.
Data We Collect
Section titled “Data We Collect”None. Context Bro does not collect, transmit, or store any data on our servers. We have no servers. All configuration (endpoints, templates, site rules) is stored locally in your browser via chrome.storage.local.
Data You Choose to Share
Section titled “Data You Choose to Share”When you explicitly share a page (via the popup, context menu, keyboard shortcut, or floating button), the extension:
- Extracts page content from the active tab (title, URL, meta description, author, main content via Defuddle, selected text, Schema.org structured data, CSS selector queries)
- Compiles it using your configured template
- Sends the compiled payload to your own API endpoint — a URL you configured yourself
The extension never sends data anywhere unless you have configured an endpoint and triggered a share action.
Auto-Capture (Scheduled Sharing)
Section titled “Auto-Capture (Scheduled Sharing)”If you enable auto-capture, the extension will periodically extract content only from domains you explicitly added to your Site Rules. Content is deduplicated (via SHA-256 hashing stored locally) to avoid sending unchanged pages. Hashes can be cleared from Settings at any time.
Live Stream Adapters
Section titled “Live Stream Adapters”On Twitch and YouTube live pages, optional adapters observe chat messages visible in your browser. Chat batches are sent to your configured endpoint. The adapters only activate on matching pages and can be disabled by not loading the extension on those sites.
What Is NOT Collected
Section titled “What Is NOT Collected”- No analytics or telemetry
- No browsing history
- No passwords or form field contents
- No data from incognito tabs
- No server-side storage
Third-Party Services
Section titled “Third-Party Services”Context Bro does not integrate with any third-party analytics, tracking, or advertising services. The only network requests are to endpoints you configure.
Data Retention
Section titled “Data Retention”All data is stored locally in your browser. Uninstalling the extension removes all stored data. You can also clear data via Settings at any time.
