Frequently Asked Questions
What is a data breach?
A data breach occurs when confidential information is stolen or accessed without authorization. This can include email addresses, passwords, personal information, and financial data from various online services.
How does this checker work?
This tool checks your email against a database of known data breaches. It uses a client-side algorithm to simulate breach lookups without sending your email to any external server.
Is my email sent to any server?

What should I do if my email was breached?
Immediately change your password for the affected service. Enable two-factor authentication (2FA) where available. Use unique passwords for each account. Monitor your accounts for suspicious activity.
How can I protect myself from data breaches?
Use a password manager to create and store unique passwords. Enable 2FA on all important accounts. Regularly check for breaches. Be cautious of phishing emails and suspicious links.
