Frequently Asked Questions
Yes. Your connection is encrypted via TLS, and we use Cloudflare for additional protection. We only use your email to check it against known breaches — we never sell or share it with third parties. You can read more in our Privacy Policy.
Our database is powered by HEROIC, which aggregates breach data from publicly disclosed incidents, security researcher contributions, and community submissions. We index over 18.9 billion records from 12,000+ known breaches. We never hack or illegally acquire data.
First, change your password on the breached service immediately. If you reused that password elsewhere, change those too. Enable two-factor authentication (2FA) on all important accounts. We recommend using a password manager like Bitwarden or 1Password to create unique passwords for every account. Our Pro plan can show you exactly what data was exposed so you know what to prioritize.
Free scans show you which breaches your email appeared in and when they occurred — no account needed. Pro unlocks the full picture: see exactly what data was exposed (partial passwords, phone numbers, addresses), get continuous monitoring with instant email alerts when new breaches are discovered, and search using usernames, phone numbers, and IP addresses.
