How it works

From one clue to the full trail in three steps.

A full search typically finishes well under a minute after you press Search, and the first matches appear as soon as the fastest sources answer.
  1. 01

    Enter one clue

    A username, an email address or a phone number. Pick the type, paste the value, press Search. No forms, no case setup.

  2. 02

    Every source is asked, live

    Tracehound sends the query to each supported source in parallel. Nothing comes from a stored copy; every answer is fresh from the site itself.

  3. 03

    Read the results, follow the leads

    Matches arrive as profile cards the moment each source answers. Filter, sort, open the profile, or (on Pro and Max) search a lead the results surfaced.

Capabilities

Built like an instrument, not a database.

Tracehound keeps no files on people. Each search asks the sources themselves, right now, and shows you exactly what they answer.

Results stream in live

Every source is queried in parallel. A match appears the moment its source answers, so you can start reading while slower sites are still responding.

Coverage you can count

Username search covers social networks, developer platforms, gaming, creative and video sites, forums, marketplaces and more. Email search finds accounts and public profiles tied to an address on supported services. Phone search validates the number, returns country, line type, formats and carrier where available, and checks the smaller set of sources that support phone lookups.

Leads and Deep Search

Profiles often list other handles and email addresses in public. Tracehound picks those up as leads you can search with one click. Deep Search goes further: it follows the leads for you, layer by layer, and merges what it finds into the same result set, each match tagged with the identifier that led to it.

  4. Layer 3

    Nothing new to follow. Refunded.

Sample data. Deep Search follows up to 3 layers and up to 5 new identifiers per layer. Each layer costs one search; a layer with nothing to follow is refunded.

Query, type, count, status, time. Never the results.

Who it is for

For people whose work starts with a name on a screen.

Different jobs, same first step: find out where an identifier shows up in public, quickly and without guesswork.

Not for screening tenants, employees or credit applicants, and never for tracking a person who does not want to be found. Read the acceptable use policy.

  • Investigators

    Map a public presence before you dig deeper

    Start a case with a handle or an address and see where it appears. The result set tells you which platforms are worth a careful manual look, and which leads to chase next.

  • Fraud and trust and safety

    Check the account behind the message

    A buyer, seller or business contact got in touch with an email or phone number. See whether it has a consistent history elsewhere, or appeared out of nowhere last week.

  • Brand protection

    Find impersonators and squatters

    Search your brand name and your team's handles across hundreds of platforms at once, and spot the accounts that are not yours.

  • Journalists and researchers

    Verify sources and trace accounts

    Confirm that a source's public profiles line up, or follow how a single handle shows up across communities. Export the result set for your notes.

  • Everyone

    See your own footprint first

    Search the usernames and email addresses you have used over the years. Close what you forgot about, tighten what you keep, and opt your email out.

Privacy and security

Built to look things up, not to keep them.

A tool that finds accounts should be careful with what it holds. Here is what that means in practice.
How data is handled

  • Not a data broker

    Tracehound has no database of people and sells no personal data. Every search goes to the public sources at the moment you run it.

  • Results are never stored

    Result data is processed in memory and sent to your browser. Your history keeps only the query, its type, the result count, status and time, and you can switch it off.

  • Anyone can opt out

    Verify an email address with a one-time code and searches for it stop immediately. Usernames and phone numbers can be blocked through a reviewed request.

  • No passwords to steal

    You sign in with a one-time code sent to your email, or with Google, so there is no password to steal or reuse. Every signed-in device is visible and revocable. Card details stay with Stripe.

Want your email address excluded from searches? Opt out with a one-time code. No account needed.

API

The same search, from your own code.

Send one request with a username, email address or phone number. Get back one JSON document with every account found and the public profile details each source returned.

  • Same engine, same data. The API runs the exact search the app runs, against the same sources, with the same opt-out and acceptable use rules.

  • Stream if you want. Add "stream": true to receive each match as its source answers, as newline-delimited JSON.

  • One allowance, automatic refunds. API searches come from the same monthly searches as the app. Failed searches are refunded automatically.

FAQ

Straight answers.

Something missing? Ask us or read about pricing.

How does Tracehound work?

You enter a username, email address or phone number. Tracehound sends that query to 430+ public sources in parallel and streams back every match as each source answers, with the profile details the source makes public. Nothing is looked up from a stored database.

Is it legal? What may I use it for?

Looking up public accounts is legal in most places, but what you do with the results is what matters. Use it for investigations, fraud and scam checks, brand protection, journalism, research and checking your own footprint.

Do not use it for employment, tenant screening, credit or insurance decisions: Tracehound is not a consumer reporting agency under the US Fair Credit Reporting Act. Never use it to stalk, harass or locate someone who does not want to be found. The acceptable use policy has the full list.

Is Tracehound a data broker?

No. Tracehound keeps no database of people, builds no profiles and sells no personal data. Each search asks the sources live, the results go to your browser, and the result data is not written to our database.

How accurate are the results?

A match means the source reported an account under that exact identifier. It does not prove that the account belongs to the person you have in mind: common handles are shared by many people, and sites change how they respond. When a source gives no trustworthy answer, it is counted as no answer instead of being guessed.

Treat each result as a lead to verify, not as proof of identity. How to read results critically.

What do you store about my searches?

If history is on, we store the query, its type, the number of results, the status and the time. The results themselves are processed in memory and never written to the database. You can delete single entries, clear all history, or switch history off in settings.

How do I stop people from finding me with it?

Anyone can block searches for their email address on the opt-out page by confirming a one-time code; it takes effect immediately. Usernames and phone numbers can be blocked through a request that we review. Opting out stops searches on Tracehound; it cannot delete your accounts on other sites.

Is it free?

You can try 3 searches a day without an account. The first 8 matches are shown in full and the rest are listed by site name until you create a free account. The free plan includes 25 searches a month. Paid plans start at $19 a month.

What is a token?

One token is one search, whatever the type and however many results it returns. Plans include a number of searches each month. There are no overage charges: when you run out, searching pauses until the next month or an upgrade. Unused searches do not roll over.

Why does phone search return fewer accounts?

Far fewer sites allow lookups by phone number than by username. Every phone search validates the number and returns number intelligence (country, line type, formats and carrier where available), then checks the smaller set of sources that support phone lookups. Expect fewer matches than with a username.

What happens if a search fails?

Searches that fail are refunded automatically. In Deep Search, layers that find nothing to follow are refunded too.

Is there an API?

Yes. The Pro and Max plans include an HTTP API that runs the same search as the app and returns the results as JSON, or as a stream of events. API searches use the same monthly allowance, with failed searches refunded automatically. Create keys in settings and start with the API reference.

How do I sign in? Is there a password?

There are no passwords. You sign in with a one-time 6-digit code sent to your email, or with Google, and your first sign-in creates the account. Codes expire after 10 minutes. Sessions last 30 days, and you can see and revoke signed-in devices in settings.

Can I cancel any time?

Yes. Cancel from your account settings and you keep your plan until the end of the period you paid for. Payments are handled by Stripe.
