Privacy Policy

1. Information we collect

We collect the minimum information needed to provide our service: your name, email address, and website URL when you sign up for a free trial or contact us. Our monitoring script collects anonymised performance metrics from your website visitors — specifically Core Web Vitals data and page view counts. We do not collect personal data from your website visitors, use cookies for tracking, or build visitor profiles. To produce PageSpeed findings, we send the public page URLs of your site (not visitor data and not page content) to Google's PageSpeed Insights API for analysis. If you choose to compare your site with up to three competitor websites or pages, the public addresses you enter are sent to Google's PageSpeed Insights API in the same way. We also read the robots.txt, sitemap and home page of those sites, keeping only counts and navigation labels, not their content. No visitor data is involved. Competitor names are shown only in your own reports and dashboard, exactly as you entered them.

2. How we use your information

Your information is used solely to provide the Web Vitals Collector service: generating weekly performance reports, sending service-related emails, and responding to your enquiries. We do not sell, rent, or share your personal information with third parties for their marketing purposes. To deliver the service we use a small number of providers: OpenAI generates the AI report summaries from anonymised performance metrics, and Google PageSpeed Insights analyses the public page URLs of your site and of any competitor sites you name. See our analytics privacy page for the full list.

3. Data storage and security

All data is processed and stored on servers within the European Union. We implement appropriate technical and organisational security measures to protect your data against unauthorised access, alteration, or destruction.

We keep an activity log of actions in your account (for example settings changes, reports sent and sign-ins). It records your account ID and role, not your IP address or the contents of the fields you change, and entries are deleted after 365 days.

4. Your rights

Under UK GDPR, you have the right to access, correct, or delete your personal data. You can cancel your account at any time and request deletion of your data by contacting us at [email protected].

5. Google Analytics (this website only)

This marketing website uses Google Analytics (GA4) alongside Plausible Analytics for research purposes — to compare and validate the accuracy of privacy-first analytics against an established industry tool. GA uses cookies and collects standard internet log information and visitor behaviour data. The data is anonymised and used solely for our internal product development and validation. No personal data from this site is shared with third parties for their marketing. You can opt out of GA tracking by using a browser extension or enabling "Do Not Track" in your browser settings.

6. Our website crawler

If site checking is switched on for a website, our crawler (WebVitalsCollectorBot) reads up to 50 public pages of that website once a week. For each page it keeps a short list of facts (status, title, description, headings, links, structured data and similar), not the page itself, and it stores no visitor data. It also records which common AI crawlers your robots.txt allows or asks to stay away; it does not send requests as those crawlers. Page facts are deleted after 90 days and the record of changes after up to 365 days. If you name competitor websites to compare with, the crawler also reads each one’s robots.txt, sitemap and home page once a week (or, for a single page you name, that page), and keeps only counts and navigation labels, for 90 days. Site owners can block it in robots.txt. See our crawler page.

7. Deleting a site’s data

When a site is removed from the service we permanently delete the site and all the data stored for it in our database, including visitor measurements, PageSpeed and website-check results, and reports and summaries. If you ask us first, we send you a copy as a zip file before deleting it. Copies held in our routine database backups are removed automatically when those backups expire.
