Accuracy, privacy and production-use notice

Results are preliminary evidence and can be incomplete, delayed or wrong. Verify important findings with the relevant provider, manufacturer documentation and an independent test before changing a production environment.

Each tool identifies whether processing stays in the browser, uses the hosted checker or reaches named public sources. Submitted targets, configurations and results are excluded from privacy-safe feedback reports.
