# Privacy Policy — Accessibility Checker Pro

**Effective Date:** July 27, 2026
**Last Updated:** July 27, 2026

## Overview

Accessibility Checker Pro ("the Extension") is a Chrome browser extension that performs automated accessibility audits on web pages using the axe-core engine. This privacy policy explains how the Extension handles user data.

## Data Collection

**Accessibility Checker Pro does NOT collect, store, transmit, or share any user data.**

Specifically, the Extension:

- Does NOT collect personally identifiable information
- Does NOT collect browsing history or web activity data
- Does NOT collect form data, cookies, or session information
- Does NOT collect authentication credentials
- Does NOT collect financial or payment information
- Does NOT collect health information
- Does NOT collect geolocation data
- Does NOT collect device or browser identifiers
- Does NOT use analytics, telemetry, or tracking services
- Does NOT send any data to external servers

## Data Storage

All audit results are stored **locally in your browser's chrome.storage.local** only. This data:

- Remains on your device exclusively
- Is never transmitted over any network
- Is automatically cleared when the Extension is uninstalled
- Is only accessible while the Extension is active in your browser

## Data Processing

When you click "Run Audit," the Extension:

1. Injects the axe-core accessibility engine into the currently active web page
2. Analyzes the page's DOM structure locally within your browser
3. Returns accessibility violation results to the Extension popup
4. Stores results temporarily in local browser storage for the current session

**All processing occurs entirely within your browser. No data leaves your device at any point.**

## Third-Party Services

The Extension does NOT use any third-party services, APIs, SDKs, or external resources. All code, including the axe-core library (v4.12.1), is bundled locally within the Extension package.

## Permissions

The Extension requests the following permissions:

- **activeTab** — Required to access the current browser tab to inject the axe-core library and analyze the page DOM for accessibility violations. This permission is used only when the user explicitly clicks "Run Audit."
- **scripting** — Required to programmatically inject the axe-core library into the active page and execute accessibility audit functions via `chrome.scripting.executeScript()`.
- **storage** — Required to temporarily persist audit results in local browser storage so the PDF export feature can access data when opening the report page in a new tab.

## Host Permissions

- **\<all_urls\>** — Required to perform accessibility audits on any web page the user is currently viewing. The Extension does NOT make network requests to these hosts; it only reads the DOM structure of the active page to run axe-core analysis locally.

## Limited Use Disclosure

In compliance with the Chrome Web Store User Data Policy and Limited Use requirements:

- **Allowed Use:** The Extension uses its permissions solely to provide and improve its core functionality — performing accessibility audits on web pages as requested by the user.
- **Allowed Transfer:** No user data is transferred to any third party. The Extension does not transmit any data externally.
- **Prohibited Advertising:** The Extension does NOT use or transfer any user data for personalized, re-targeted, or interest-based advertising.
- **Prohibited Human Interaction:** No human has access to any user data through this Extension. All processing is automated and occurs entirely within the user's browser.

## Children's Privacy

The Extension does not knowingly collect any personal information from children under the age of 13, or from any users regardless of age, as no data collection occurs.

## Changes to This Policy

If this privacy policy is updated, the changes will be reflected in the Chrome Web Store listing and in the Extension's source repository. Continued use of the Extension after changes constitutes acceptance of the updated policy.
