Privacy and controller data

The tester processes controller readings in this browser after you start observation. Our application does not upload those readings, retain a controller identifier, or put results in URLs. There is no account or cloud result history.

Local storage and result downloads

We store your chosen color theme in local storage, if available. Test results remain in page memory until you retry, reload or leave. JSON and image exports are generated locally; the raw controller identifier is excluded. You decide whether to share downloaded files.

Fonts, hosting and third parties

Space Grotesk is served with the site, not requested from a remote font service. The site loads no analytics scripts. The hosting provider may process normal request information such as IP address and browser headers; this is not a promise of zero data collection by infrastructure providers. Ads load automatically as described below.

Advertising

This site loads ads from Adsterra automatically, served through bauval.org and abscloud.org. The page loads a native banner near the top of the page, a social bar, and a popunder that can open a new tab after you click. These third-party formats may set cookies and process technical information such as your IP address, browser and device details, page URL, and ad interactions.

The tester and local downloads do not depend on ad code. Ad blockers can prevent ads; they do not affect the tests.

We do not pass controller readings to Adsterra. The ad scripts are third-party code that run in the page, not in a separate sandbox; review Adsterra’s privacy policy and cookies policy for its data practices. Adsterra controls ad selection and measurement, not us.

The ad code is controlled by Adsterra, including how it responds to browser privacy signals and cookies. Use your browser’s site-data controls to remove cookies set on Adsterra’s domains.

Scope and changes

This page describes the current static build. If the ad integration or data handling changes, this page will be updated with it. Site content remains readable without ads or JavaScript; the controller tester needs JavaScript for readings.
