Summary: AI Browser Guard processes all data locally on your device. No data is collected, transmitted, or shared with any external server, third party, or analytics service.
1. What This Extension Does
AI Browser Guard is a Chrome extension that detects, monitors, and controls AI agents operating in your browser sessions. It provides:
Detection of automated browser control (WebDriver flags, CDP connections, behavioral analysis)
An emergency kill switch to terminate agent access
A delegation wizard to define access boundaries for AI agents
Boundary violation alerts when agents attempt unauthorized actions
A session timeline logging agent activity
2. Data We Collect
We do not collect any personal data.
The extension processes the following information entirely on your local device:
Detection signals: Browser automation indicators such as navigator.webdriver flags, CDP markers, and event timing patterns. These are analyzed locally and never transmitted.
Session logs: A chronological record of detected agent actions (timestamps, action types, target URLs, CSS selectors, and outcomes). The last 5 sessions are stored locally.
Delegation rules: Access control rules you configure (presets, site patterns, time bounds). Stored locally in chrome.storage.local.
Violation records: Logs of boundary violations (what was attempted, which rule blocked it). Stored locally, limited to the 100 most recent entries.
3. How Data Is Stored
All data is stored in chrome.storage.local, which is a browser-provided storage mechanism that keeps data on your device only. Data is not synced across devices.
Session history: Last 5 sessions retained
Detection log: Last 100 entries retained
Delegation rules: Retained until you change or remove them
User settings: Retained until you change them or uninstall the extension
Uninstalling the extension deletes all stored data.
4. Data We Do NOT Collect
No personal information (name, email, account credentials)
No browsing history beyond what is logged in the session timeline
No page content, form data, or user input
No cookies, authentication tokens, or session identifiers
No analytics, telemetry, or usage statistics
No crash reports or error telemetry
5. Network Communication
This extension makes zero network requests. All detection, analysis, and enforcement happens locally in your browser. There are no external API calls, no update checks beyond Chrome's built-in extension update mechanism, and no data transmission of any kind.
6. Permissions Explained
The extension requests the following Chrome permissions:
activeTab: Access the currently active tab to detect automation and enforce delegation rules.
storage: Store session logs, delegation rules, and settings locally on your device.
alarms: Schedule periodic checks for delegation rule expiration.
scripting: Inject content scripts that detect automation frameworks and enforce boundaries.
tabs: Monitor tab navigation to detect agent activity across tabs and broadcast kill switch commands.
notifications: Display boundary violation alerts when an agent attempts unauthorized actions.
host_permissions (<all_urls>): The content script must run on all pages to detect automation frameworks, since AI agents can operate on any website. Detection cannot be limited to specific domains without losing coverage.
7. Third-Party Services
This extension does not use, integrate with, or transmit data to any third-party services, APIs, analytics platforms, or advertising networks.
8. Children's Privacy
This extension does not knowingly collect any information from anyone, including children under 13. Since no personal data is collected, COPPA considerations do not apply.
9. Changes to This Policy
If this privacy policy changes, the updated version will be published at this URL with a new "Last updated" date. Material changes affecting data collection would require a new extension version review by the Chrome Web Store.
