The test starts as soon as you open the page, and its results are sent to our server and saved. This page explains what that means. Please leave the page before using the test if you do not agree.
What is saved
- The measurements shown on the page: browser and operating system, screen, CPU and GPU details, graphics and audio results, installed fonts, languages, time zone, media devices and permissions
- Network details gathered through WebRTC, which can include an IP address
- Summary values calculated from these measurements, used to recognize repeat records from the same device
- The date and time of the record
Why it is saved
We use the measurements to show you your results and to study how real devices and browsers behave. Values derived from many records are used to build device profiles for browser compatibility testing.
How long it is kept
Records have no fixed deletion date. They do not contain your name, but a device's combined measurements can be unique, so treat them as potentially personal data.
Third-party services
The site uses Google Tag Manager and Google Ads tags to measure visits and advertising, and it is served through a content delivery network. These providers process technical data such as your IP address under their own terms.
