Lead Lock Systems LLC uses the Google PageSpeed Insights API to analyze website performance, Core Web Vitals, loading speed, and technical health metrics for any submitted URL. No user login is required. No personal data is collected.
This tool is an internal and client-facing web performance diagnostic application developed and operated by Lead Lock Systems LLC. It calls the Google PageSpeed Insights API to retrieve objective, publicly available performance data for any given website URL.
The application is used to measure how fast a website loads, identify technical issues affecting performance, and generate actionable recommendations for improvement. Results are generated in real time using Google's PageSpeed Insights scoring engine and are based solely on the URL submitted by the user — no accounts, credentials, or personal information are involved.
This tool does not interact with Google user accounts, Google Drive, Gmail, or any other Google user data. It exclusively uses the PageSpeed Insights API, which is a publicly accessible, read-only performance measurement API.
Measures Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP) — Google's official user experience metrics.
Retrieves the overall Lighthouse performance score (0–100) for both mobile and desktop environments, giving a composite view of page speed health.
Captures Time to First Byte (TTFB), First Contentful Paint (FCP), Speed Index, and Total Blocking Time (TBT) to identify where page load time is being lost.
Returns detailed audit results including render-blocking resources, unused JavaScript/CSS, image optimization opportunities, and server response time issues.
Analyzes the submitted URL separately for mobile and desktop strategies, reflecting how Google's crawler evaluates pages across different device types.
Retrieves both real-world Chrome User Experience Report (CrUX) field data and controlled Lighthouse lab data to provide a complete performance picture.
We are committed to full transparency on what data our application requests, processes, and stores. The table below outlines every data point involved in the operation of this tool.
The following describes exactly how this application functions from the moment a user submits a URL to the moment results are displayed.
The user enters a publicly accessible website URL into the input field. No login, account creation, or personal information is required at any point.
Our server sends a request to the Google PageSpeed Insights API endpoint with the submitted URL and our server-side API key. The request is made for both mobile and desktop strategies.
Google's PageSpeed Insights service runs a Lighthouse audit on the submitted URL and returns a JSON response containing performance scores, Core Web Vitals, audit results, and diagnostic data. This is entirely based on the public URL — not on any user account.
The response data is parsed and presented to the user in a structured, readable format showing scores, metrics, and recommendations. The raw API response is not stored on our servers after delivery.
No session data, user profile, or analysis history is retained. Each request is stateless and independent. The user may submit another URL to begin a new analysis at any time.
This application operates in full accordance with the Lead Lock Systems LLC Privacy Policy. As stated in that policy, we do not sell, share, or monetize any user data. View our full Privacy Policy here.
This application's use of Google API Services is limited strictly to the PageSpeed Insights API for read-only performance data retrieval. We comply with the Google API Services User Data Policy, including the Limited Use requirements.
This application does not request any OAuth scopes. It does not access Google user accounts, contacts, files, email, or any other personal Google data. API access is performed using a standard API key only.
