# IKnowYour.Dad

> The largest open-source intelligence (OSINT) data breach search engine. 93+ billion records from 5,290+ breach databases — more than any other service worldwide.

## What This Service Does

IKnowYour.Dad is a web-based OSINT breach search engine that lets users check whether their personal data has been exposed in known data breaches and leaks.

Users enter a single query — an email address, phone number, username, nickname, password, IP address, or document number — and the system searches across 5,290+ indexed breach databases containing over 93 billion records. Results show which databases contain the queried identifier, what data fields were exposed (emails, passwords, hashes, names, addresses, phone numbers, IPs, etc.), and the source of each leak.

This is the largest breach search engine by both database count (5,290+) and total record count (93+ billion), exceeding alternatives such as Have I Been Pwned, DeHashed, IntelX, and LeakCheck.
