Display test data
The pixel tools run in your browser. They do not request camera, microphone, screen-capture, or file-upload permission. The site does not receive an image of your display, a count of suspected pixels, your checklist selections, custom test color, or decision-tree answers. Those interactions exist only in the open page and are discarded when the page is closed or reloaded.
Local storage
The theme control stores one preference named display-theme in browser local storage so the chosen light or dark appearance can be restored. The preference contains only the value light ordark. You can remove it through browser site-data controls.
Analytics in this build
This build has optional analytics enabled through the deployment configuration. It can load Google Analytics 4 and Microsoft Clarity. The integration may record page use and minimal tool events such as starting a tool, entering fullscreen, changing a pattern, or completing a sequence. It does not intentionally send custom colors, checklist answers, or interpretation selections. Review the applicable provider policy and deployment settings for retention and control details.
Hosting and ordinary network data
Like any website, the deployed static host or network provider may process ordinary request information such as IP address, requested URL, timestamp, user agent, security signals, and cache status to deliver and protect the site. Retention and access depend on the host selected by the site operator. This application has no database or account system of its own.
External links
Links to another site are governed by that site’s privacy practices. Opening a mail link, manufacturer support page, or policy source leaves this site.
