Frequently Asked Questions
How does the Email Breach Checker work?
We check your email domain against a curated database of publicly known data breaches. The analysis runs entirely in your browser - your email address is never sent to our servers.
Does this check if my specific email was breached?
This tool checks if your email provider/domain has been involved in known data breaches. For individual email breach checking, we recommend using haveibeenpwned.com alongside this tool.
What should I do if my provider has breaches?
Change your password immediately, enable two-factor authentication, and consider switching to a more secure provider. Use temporary emails from Temp Postal for non-essential signups to minimize future exposure.
Is my email stored when I use this tool?
No. The analysis is 100% client-side. Your email never leaves your browser.
Don't Wait for the Next Breach
