Answers before an account exists

What the signup asks for, how payment works, where the data comes from, and what survives a search.

Do I need an email address or a real name to sign up?

account

No. A username and password is the entire signup. There is no email, phone, or real name field, and the CAPTCHA at registration is the only checkpoint.

How do I pay?

payment

Crypto only: BTC, ETH, LTC, USDT, USDC, BNB, and TRX. There is no card option and no billing name. Pick monthly, yearly, or a one-time lifetime license.

Does a subscription auto-renew, and can I cancel?

payment

No auto-renew. A monthly or yearly purchase buys a fixed block of access (30 days or 365 days) and simply lapses at the end. Nothing recurring is stored that could charge you again. You can buy the same plan again at any time to extend it, and the new time is added to whatever you have left. Lifetime is a single payment that never renews.

Are refunds available?

payment

All sales are final. That is the reason any account can run a breach search and see how many records exist before paying to view them.

What happens if I buy lifetime while I am subscribed?

payment

The lifetime plan takes effect immediately. Time remaining on the subscription is not refunded.

Is breach search included in the free plan?

features

The free plan covers 13 standalone OSINT tools. Breach search with full record values, the correlation graph, and hash lookup need Premium. Stealer logs, NPD, and Blackbird need Pro.

What if a search returns nothing?

features

Run it on a free account first. The record count is shown before you pay to view the values, so you can confirm there is something to find.

Where does the data come from?

features

Several breach corpora and stealer-log collections, queried together. Every hit names the source it came from and is marked fresh or stale by age.

How many searches do I get per day?

features

Premium allows 500 searches per day and Pro allows 2,000. The counter resets at 00:00 UTC and unused searches do not roll over.

Who is this built for?

features

Security researchers, investigators, and IT teams checking exposure. Use it for authorized research and investigation, not to harass or endanger anyone.

Does it work over Tor or a VPN?

technical

Yes, identically. The CAPTCHA at registration is the only checkpoint.

Can I reach the tools from my own code?

technical

Yes. Premium and Pro accounts get an API key and an MCP server, so Claude Desktop or any MCP client can call the tools under the same tier, quota, and rate limits as the web account.

What do you keep?

privacy

Results are stored for one hour so you can return to them, then deleted. The queries themselves are never written to a log.

Can you see what I searched for?

privacy

The query is not logged, so there is no stored record of the identifier you looked up. Results live for one hour and then go away on their own.
