Hicy — is a data breach search & notification app that monitors online data leaks for user's security. Hicy aggregates data that's been exposed publicly and enables individuals to assess their exposure.

◆ How does it work?

Searches only require an email address and provide immediate feedback. The notification service monitors for ongoing exposure and notifies an address owner if it subsequently turns up in a data breach.

◆ What exactly is a data breach?

A data breach happens when personal or private information gets exposed, stolen, or copied without permission. These security incidents can be a result of cyber attacks on websites, apps, or any database where people's personal information resides.

◆ Why am I in this breach?

Hackers often target massive companies with millions of users to get as much personal information and credentials as they can. These hackers look for a security weakness — the digital equivalent of leaving a door unlocked or window open.

◆ What information gets exposed in data breaches?

Many data breaches expose email addresses and passwords. Others expose more sensitive information such as credit card numbers, passport numbers, and social security numbers.

◆ Do I need to be worried if my information gets exposed during a data breach?

You should take steps to protect your personal information and accounts. If your password and email address get exposed, hackers can sell that information on the dark web to the highest bidder.
