Overview
Web Checker: SEO & Speed ("the Extension") is a technical SEO and page-performance audit tool that runs entirely client-side inside your browser. The Extension does not collect, store, or transmit your personal data to any server operated by its developer.
Data We Process
SERP Comparison Mode (on google.com/search pages)
- The Extension reads the URLs of the top 10 organic search results shown on the current Google Search page.
- It then makes a direct
fetch()request, from your device, to each of those result pages to measure HTML size, DOM element count, page title, and H1 tag — purely for competitive benchmarking. - This data is processed entirely in the popup window's memory and disappears when the popup is closed, unless you explicitly export it to a CSV file, which is saved directly to your own device.
Core Web Vitals Mode (on any other page)
- The Extension reads standard, built-in browser performance data (Largest Contentful Paint, Cumulative Layout Shift, Time to First Byte, First Contentful Paint, and resource sizes) via the web's standard Performance API.
- None of this data leaves your device.
Data Sharing
The Extension does not share, sell, or transfer any data to third parties. There is no analytics SDK, no tracking pixel, and no telemetry sent by the Extension itself.
Permissions We Request
| Permission | Why it's needed |
|---|---|
activeTab |
Lets the Extension read the URL of the tab you're currently viewing, only after you click its toolbar icon, to decide which audit mode to run. |
scripting |
Lets the Extension run its data-extraction logic on the page you're viewing, triggered only by your click on the icon. |
optional_host_permissions( https://*/*, http://*/*) |
Requested only when you use SERP Comparison Mode, and only after you click the in-app "Allow & Start Audit" button. This lets the Extension fetch competitor pages' HTML for comparison. Core Web Vitals Mode never requests or uses this permission. |
Local Storage
The Extension does not use localStorage, chrome.storage, or any persistent storage mechanism. All data held by the Extension is temporary (in-memory only) and is cleared when the popup closes.
Outbound Links
The Extension includes an optional "Contact Faiz" button that, if clicked, opens drfaizazizan.com in a new tab, with standard UTM campaign parameters appended to the URL (used only for the destination site's own analytics, not for tracking you across other sites). Clicking this button is entirely optional and is never triggered automatically.
Children's Privacy
The Extension is a technical tool intended for website owners, marketers, and developers, and is not directed at children. It does not knowingly collect data from children.
Changes to This Policy
If this policy changes, the "Last updated" date at the top of this page will be revised accordingly. Continued use of the Extension after changes constitutes acceptance of the updated policy.
