5 Whys Career Studio is a static browser-first site. The core career tools run locally in your browser, and the current infrastructure list is intentionally short.
Infrastructure provider
Scope
The career drafts, resume bullets, interview notes, and networking practice text you enter in the tools are handled in the browser during normal use. The project does not use a production account system, payment processor, or server-side career-document database for the public tools.
Cloudflare may process request metadata to deliver the pages, block abuse, apply security controls, and provide aggregate analytics. That infrastructure processing is separate from the career content you draft locally inside the browser.
The practical boundary is simple: Cloudflare helps the site load and stay protected, while the public career tools are designed around local browser work. Resume bullet drafts, interview story notes, networking practice answers, and reflection text are not sent to a 5 Whys account database during normal use.
If you contact Jonathan directly from outside the tool, that message is handled through the channel you choose. It is separate from the static site and should be treated like normal email or contact-form correspondence.
If the hosting or analytics setup changes, this page should be updated before the new provider is used for production traffic.
