Local-first utility

Privacy

The diagnostic parser, evidence readers, verification loop, and Evidence Pack run in your browser. TechClassy does not intentionally store the raw text you paste, Event Viewer or update-log excerpts, full command output, usernames, local file paths, dump files, device serial numbers, observations, parsed summaries, or generated Evidence Packs.

No advertising, analytics, session replay, account system, upload surface, or third-party diagnostic script is loaded in this release. Standard hosting security logs may contain request metadata such as time, requested path, and network information; diagnostic and evidence text is not sent as a URL parameter or API body by the tool.

Use boundary

TechClassy organizes evidence and reviewed next checks. It is not a substitute for Microsoft, an OEM, an employer's IT team, or a qualified repair professional. Results distinguish confirmed facts from possible causes and do not guarantee a repair.

Back up important data before making system changes. Stop when an action requires credentials, firmware changes, disk work, account recovery, or a command whose prerequisites you cannot verify.

Independent operation

This is a newly researched, independently operated diagnostic product. It does not claim to be the prior TechClassy editorial team or a continuation of prior authorship.
