What is stored on your device
The site stores one saved test in your browser so the guided check and result page can work together. It can include the answers and optional device or purchase details you enter.
What Analytics measures
We use Google Analytics 4 to understand visits and improve the site. It can measure page views, approximate location, browser and device information, scrolling, and outbound-link clicks using cookies or similar identifiers. We also count test starts and completions using only the kind of tool. A manual pixel-test completion means all five core colors were viewed; leaving a test early does not count as completion. These events do not include your observations, diagnosis, dot location, device details or other form entries. We do not use these measurements for advertising personalization.
Google processes Analytics data under the Google Privacy Policy. You can limit this measurement by blocking or clearing cookies in your browser.
What you choose to share
Opening a manufacturer link takes you to that provider’s website as usual. Copying or downloading a report is initiated by you; the report is not automatically uploaded.
How to delete your saved test
Use “Delete saved test” on the result page, clear this site’s browser data, or use a private-browsing session.
