What the tests do
Visual patterns are generated locally by your browser. ScreenProbe does not capture, upload or inspect the contents of your display.
Minimal access analytics
We record page views and interactions such as starting a test, entering fullscreen and changing a pattern. Records contain the page, test, interface language, coarse browser language and—when Cloudflare provides it—a two-letter country code. We do not store IP addresses.
A random identifier is kept in session storage for the current browser tab and pseudonymised on the server. It expires with the session and is used only for aggregate visit counts. Do Not Track is respected.
Suggestions
If you use the suggestion box, we store the category, message, page, language and optional email address you submit. Email is only used to reply when necessary. Suggestions are not sold or used for advertising.
Retention and choices
Analytics should be retained only as long as useful for aggregate product decisions. Suggestions are retained while they are reviewed or acted on. You can enable Do Not Track to disable the custom analytics request. A contact address for access or deletion requests will be published before public launch.
Future advertising
ScreenProbe currently has no advertising. If advertising is introduced later, this policy and any required consent controls must be updated before ad scripts are enabled. Ads will never appear over an active fullscreen test.
