🔎 BACKGROUND CHECK

A public-footprint check. Give it a name, a handle, an email, a profile, or a domain — it walks the public web with Onion's own search stack and lays out what a stranger can find, with a source link on every claim.

What this is for: checking your own footprint, a public creator or business, or a handle someone handed you.
Verify before you act. Same-name strangers exist, search snippets go stale, and a match here is a lead — not proof about a person.
What it never shows (either mode, by design): home or street addresses, personal phone numbers, SSNs, exact dates of birth, financial data, family or associates, current location, anything behind a login or paywall, and anything out of leaked-data dumps or people-search brokers. Search snippets are stripped of those patterns by the Bridge before they reach this page.
Sources: the public web (via the Onion Core Bridge), the public domain registry (RDAP), the Wayback Machine (admin mode), and breach notification metadata only — breach names, dates, and what kinds of data a breach contained. Never breach contents: no passwords, hashes, or records, from any source, in either mode. Nothing is scraped over Tor and no leak or marketplace sites are touched — Tor here only hosts Onion's own services. Lookups are not stored on any server; reports live in this tab until you clear them (or save a case file, admin mode — stored only in this browser).

Who are we looking at?

Admin mode

The deep tier: a bigger query sweep (name variations, handle permutations, more platforms, public business & court-record mentions), Wayback history, inline breach exposure, batch checks, and case files. Gated by the Onion Core passcode — typed here, sent as a header, checked by the Bridge. It is never stored, logged, or baked into this page. The never-show list above still applies in full; the one difference is that contact details a subject publishes on their own site or business listing may be shown, labeled as such.
