Privacy Policy

Last updated: March 2026

Overview

PageNab is a Chrome extension that captures web page context (screenshots, console logs, network requests, DOM snapshots, cookies, storage, user interactions, performance metrics) and copies it to your clipboard for use with AI coding assistants. PageNab is designed with privacy as a core principle.

Data Collection

PageNab does not collect any data.

No personal information is collected
No usage analytics or telemetry
No tracking cookies or identifiers
No data is sent to any server
No third-party services are used

Data Storage

All captured data stays exclusively on your local machine:

Clipboard: Page context (text + screenshot image) is copied to your clipboard for immediate pasting
Downloads folder: Screenshots are saved as PNG files for persistence
Extension local storage: Capture history (thumbnails + text data) is stored locally within the extension

You have full control over this data:

Clear your clipboard at any time
Delete downloaded screenshots from your Downloads folder
Delete captures from the extension's history via the popup

Data Sharing

PageNab never shares any data with anyone.

No data leaves your computer
No server-side processing
No cloud storage
No analytics platforms
No advertising networks

Data Sanitization

PageNab automatically sanitizes sensitive information from captures:

Network requests: Authorization headers, cookies, API keys, and tokens are stripped from captured network data
DOM snapshots: Password field values are replaced with ***
Cookies: Values are truncated; cookies with sensitive names (containing "token", "session", "auth", "key", "secret", "password") have their values fully masked with ***
Storage: Keys containing sensitive terms have their values masked; all values are truncated to 200 characters
User interactions: Input field values are ALWAYS masked with ***; no individual keystrokes are captured

Captured Data Types

PageNab can capture the following data types depending on the selected preset (Light, Full, or Custom):

Data Type	Description	Sanitized
Screenshot	Visual capture of the page	No PII captured
Metadata	URL, title, viewport, user agent	Public page info only
Console logs	Browser console messages	No sanitization needed
Network requests	Failed/slow HTTP requests	Headers sanitized
DOM snapshot	Cleaned HTML of the page	Scripts removed, passwords masked
Cookies	Non-httpOnly cookies (via document.cookie)	Values truncated/masked
Storage	localStorage and sessionStorage contents	Sensitive keys masked
User interactions	Last 50 clicks, scrolls, inputs	All input values masked
Performance metrics	Load times, Core Web Vitals, memory	Technical metrics only

Important: Cookies are read via document.cookie in the content script (non-httpOnly cookies only). PageNab does NOT use the cookies Chrome permission and cannot access httpOnly cookies.

Permissions

Permission	Why
`activeTab`	To capture the content of the page you're currently viewing, only when you click the extension
`clipboardWrite`	To copy page context (text + screenshot image) to your clipboard
`storage`	To save your preferences and capture history locally
`downloads`	To save screenshots to your Downloads folder for persistence
`notifications`	To confirm when a capture is complete
`scripting`	To inject the content script that collects page data (console, network, DOM, etc.)

PageNab does not request:

<all_urls> in permissions (the content script for interaction tracking uses <all_urls> in content_scripts, but this does not grant arbitrary access)
tabs (no access to your tab list)
history (no access to your browsing history)
cookies (no access to httpOnly cookies via Chrome API)
webRequest (no network interception)
nativeMessaging (no external processes)
