Product principles
The useful result comes before monetization, tests request sensitive permissions only after a click, reports remain local by default, limitations are stated beside the result, and no page claims that browser software can certify internal hardware.
Method
Each diagnostic separates observable browser behavior from interpretation. Guided flows combine checks into practical sequences and explicitly leave room for physical inspection, operating-system tools, official diagnostics, and professional repair.
Release scope
Version 1.0 includes nineteen live browser checks, six guided flows, eight guides, English, Spanish, and Brazilian Portuguese routes, local reports, JSON and standalone HTML export, print/PDF support, search, and an offline shell.
Release boundary
The public site intentionally avoids a contact inbox and keeps diagnostic data local. Use the documented product boundaries and the repository history when evaluating the release.
