Privacy Policy - PageLint

Last updated: April 2026

Overview

PageLint is a Chrome extension that analyzes the currently open web page inside Chrome's Side Panel. It helps users review metadata, heading structure, links, images, structured data and search/social previews before publishing or sharing a page.

Data collection

PageLint does not collect, transmit or sell user data.

All analysis is performed locally on the user's device. The extension reads the HTML structure of the page currently being reviewed and generates results directly in the browser.

What data is processed

While PageLint is in use, it may read the following information from the current page:

• Page title and meta tags
• Heading structure (H1-H6)
• Image attributes such as alt
• Link URLs and anchor text
• Structured data blocks such as JSON-LD
• Open Graph and Twitter preview metadata

This data is used only to generate the audit for the current page and is not sent to any external service.

Local storage

PageLint may use chrome.storage.local for lightweight extension state and future preferences. No audit data is transmitted to external servers.

Permissions used

• storage — Stores lightweight local extension state and future user preferences.
• sidePanel — Displays the extension UI in Chrome's Side Panel.
• activeTab — Accesses the currently active page selected by the user.
• scripting — Runs a local page analysis function on the current page.
• tabs — Detects tab changes and page reloads so the audit can refresh automatically.
• host_permissions: <all_urls> — Allows PageLint to analyze any page the user chooses to review in Chrome.

No external communication

• No analytics or tracking tools are used.
• No user account is required.
• No browsing history is sent to servers.
• No page content is uploaded for remote processing.
• No data is shared with third parties.

Data retention

PageLint does not maintain a remote database of user activity. Any lightweight local state remains on the user's device and can be removed by clearing extension storage or uninstalling the extension.

If this privacy policy is updated, the changes will be reflected on this page with an updated date.
