The site is run by a white hat hacker, Troy Hunt. It allows you to search any email address, which is already in the database of hacked accounts. Nothing is stored, and even if it was, nothing particularly useful would come of it. The only exception is for sensitive breaches, like Ashley Madison for example. In that case, you need to verify the email address is yours before information is returned regarding it. I can't quite remember the details why. Signing up for breach alerts is another option, which many other services already offer. But that stuff is made very clear. It's a bit of a paradox, that a site like that looks much scarier than the initial sites that breached to the data to begin with. LinkedIn looks safer than HIBP. Looks can be deceiving.

Troy Hunt is a renowned security expert, working for Microsoft. He did consider to give someone else the responsibility for this site some years back. But he got cold feet when realising those willing to take that task didn't necessarily have the purest intentions with the site data, and it would not be in the best interest of its users. Not too long after, he started selling the API access to sites wanting to query if usernames, e-mail addresses, etc was comprised. I believe this service can also do API callbacks when their users is caught in a compromise. This service offering mostly funds HIBP, in addition to other donations. I have several of my own domains listed there, and occasionally I do get some warnings when new breaches are registered. That often explains quite well when an e-mail address is getting a lot more unexpected spam or phishing attempts.

Troy Hunt: 2 Billion Email Addresses Were Exposed, and We Indexed Them All in Have I Been Pwned
November 14, 2025 - Edit: Just to be crystal clear about the origin of the data and the role of Synthient (who you’ll read about in the next paragraph): this data came from numerous locations where cybercriminals had published it. Synthient (run by Ben during his final year of college) indexed that data and provided it to Have I Been Pwned solely for the purpose of notifying victims.

If I'm honest, I was never that keen on a merch store for Have I Been Pwned. It doesn't make the code run faster, nor does it load any more data breaches or add any useful features to the service whatsoever. But... people were keen. They wanted swag they could wear or drink from or whatever, and it's actually pretty cool that there's excitement about HIBP as a brand.
