01Local browser processing
Patterns, size calculations, frame sampling and touch records run in your browser. There are no file uploads, user accounts or cloud test records. Touch traces live in page memory and are cleared on refresh.
Privacy Policy
Learn which browser information is read, which preferences are stored and how data is handled.
02Device information we read
The resolution page reads screen dimensions, window dimensions, devicePixelRatio, browser color depth and media-query capabilities. These readings are displayed on the page and do not identify the panel model. Google analytics tags may also process basic browser and device information.
03Local preferences
Your theme preference is saved in localStorage under screentest-theme. You can remove it by clearing site data in your browser; the main pages remain accessible when storage is disabled. Google analytics tags may use cookies, depending on the configuration published in the container.
04Third-party services and resources
The production site loads analytics tags through Google Tag Manager. Google may process page visits, browser and device information; the exact behavior depends on the published tag configuration. Our tools do not send touch paths, test-pattern settings, frame-rate samples or calculator inputs as analytics events. Local previews do not load analytics tags.
05External links
External pages are the responsibility of their providers. Actions such as copying the current URL only occur when you request them.
06Updates to this notice
This notice reflects the current implementation. It should be updated when features, deployment or data processing change. For questions, please use the contact page.
