Fusebox privacy policy

Fusebox is paid software, not a lead-generation funnel. The extension analyzes the active tab, keeps the verdict flow local-first, and makes only a short, named list of external lookups. Your browsing never leaves your machine.

What stays local

  • Current tab URL and hostname
  • DOM-derived metadata such as title, headings, links, images, scripts, stylesheets, Open Graph tags, Twitter card tags, and JSON-LD
  • Technology, origin, hosting, tracker, SEO, history, and security-header reports
  • Deterministic verdict findings and recommended actions
  • Extension preferences, feature flags, license state, and local cache entries

External lookups

Some reports require deterministic external lookups. Fusebox sends the minimum value required for the lookup and caches results per domain where possible.

AI modes

The deterministic verdict runs without sending page content to a hosted LLM. When Chrome's on-device Prompt API is available, Nano verdicts run inside the browser after user consent for model download. If a user enables a BYO-key cloud AI mode, selected report context and their prompt may be sent to the configured provider.

Alpha tools

Network and Console tools can expose request, response, and console details from the inspected page. They are kept behind the Alpha Features toggle for debugging and agent workflows, not promoted as the default product surface.

Data sale

Fusebox does not sell browsing history, page content, analytics profiles, or report data. The business model is the extension license.
