We collect information about you when you provide it to us and when you use GTmetrix, as described below.

We collect information about you that you provide to us:

  • Basic Account information: If you register for a GTmetrix account, we collect your name (optional) and e-mail address.
  • Payment information: If you sign up for a GTmetrix PRO account, we collect your payment information.
  • Test details: If you use the test options (e.g., Cookies, HTTP authentication) when performing a GTmetrix test, those settings are saved for future tests.
  • Communications with us: If you contact us via the Contact form, e-mail, or social media, this information is collected.
  • Mobile Number (optional): We collect your mobile number if you enable Multi-Factor Authentication (MFA) via SMS or opt-in to performance alerts.

Information we collect automatically

We also collect some information automatically:

  • Logs: Like most services, we log access to our services in log files. This data includes date and time of access, IP address, browser user agent, and the page visited.
  • Usage information: We collect information on how you are using GTmetrix.
  • Cookies / Web storage: We use cookies and web storage (i.e., localStorage/sessionStorage) for the sole purpose of preserving state. For example, to remember who you are logged in as, or to remember where you are in performing a task. If you are on a Guest/Basic (Free)/Trial account, we also use cookies to serve you relevant advertisements.

Information we receive from other sources

We collect information from these third-party sources:

  • Google Analytics: a web analytics service provided by Google Inc.

    Google Analytics uses cookies to enable analysis of your use of the website. In using Google Analytics, GTmetrix employs the "anonymizeIp" feature which masks part of your IP address before storing or processing it.

    Our Google Analytics is configured to disable all data sharing options (i.e., our Google Analytics data is not shared with other Google products and services). Google Analytics' advertising features are also disabled (i.e., Remarketing and Advertising Reporting features).

    You can disable Google Analytics tracking completely by using the Google Analytics Opt-out browser add-on.

  • Mixpanel: a product analytics service provided by Mixpanel, Inc.

    Mixpanel uses cookies and similar technologies to collect pseudonymized information such as pages visited, actions taken, device type, browser, and approximate location (based on IP address). This helps us analyze feature usage, identify performance issues, and improve the overall experience.

    GTmetrix does not send personally identifiable information (such as email or name) to Mixpanel unless explicitly provided during your use of our service.

  • VWO (Visual Website Optimizer): a website optimization and A/B testing service provided by Wingify Software Pvt. Ltd.

    VWO uses cookies and similar technologies to determine which version of a page a visitor sees, maintain consistency between visits, and measure how different versions perform.

    This data is aggregated and pseudonymized; it does not contain personally identifiable information.

    You can learn more about how VWO handles data in its Privacy Policy and Cookies Notice.

  • Third-Party Advertising Partners:.

    Third-Party Advertising Partners use cookies to develop and display personalized content and advertising (and work with third parties who do so) tailored to your interests and/or location and to measure its effectiveness. No identifiable personal information is collected and/or shared.
