Scope and privacy
Inputs and results are encrypted in our database and tied to this browser’s private ownership cookie. Only public destinations are allowed. Reports last up to 24 hours within the shared 500-report history; private recovery backups have a separate lifetime.
Browser experiments use Chromium from our server. They may observe a different response from another device, location or authenticated user. Automated accessibility findings need manual follow-up, consent observations are not legal certification, and rendered content does not prove search indexing.
