What do you want to check?
Five tasks run locally in your browser. A receipt shows each check’s result and limits.
Material is checked in your browser. Product statistics count task-page opens and outcomes as daily aggregates when collection is available; this does not affect a check. Product events exclude checked text, queries, file contents and names, and URLs. The service does not search for people or publish findings automatically.
