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.
| Provider | Purpose | Data sent |
|---|---|---|
| Google DNS-over-HTTPS (dns.google) | DNS records | Domain name |
| RDAP registries | Registrar, domain age, expiry, and status | Domain name |
| ipinfo Lite (ipinfo.io) | IP, ASN, and network owner context | IP address and optional user-provided token |
| RIPEstat | ASN fallback when ipinfo lacks ASN data | IP address |
| Wayback Machine CDX (archive.org) | Historical capture counts and first/last snapshots | Domain name |
| Fusebox license Worker | License validation, restore, and manage-license support | License key, install ID, and extension version |
| Payment processor (via checkout) | Purchase and receipt handling | Buyer and payment details, handled by the processor |
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.
