About EmailLeaked
Last updated: June 2026
EmailLeaked is a free, independent data breach checker founded in 2026. It gives everyday internet users a straight answer when they hear about a hack or data breach — no technical knowledge required, no account, no paywall. The site combines instant breach checking with plain-English security guides that explain what exposure means and what to do about it.
What EmailLeaked does
The email breach checker looks up any email address against known breach databases in real time and returns results immediately, showing which incidents the address appeared in, what data was exposed, and what steps to take. The email address is discarded immediately after the check — it is never stored. The password checker uses k-anonymity: the password is hashed locally in the browser using SHA-1, and only the first five characters of that hash are sent to the lookup service, so the full password never leaves the device. Both tools are free and require no account or registration.
Beyond the tools, EmailLeaked maintains a continuously updated database of tracked breach incidents, each with a plain-English summary, a list of exposed data types, and a risk level. The blog publishes practical security guides covering password safety, two-factor authentication, account recovery, and breach response — written for ordinary users, not security professionals.
How the checker works
When a user enters their email address, it is sent to EmailLeaked's API, which checks it against known breach records in real time. The result is returned immediately — showing which breaches the email appeared in, what data was exposed, and what steps to take next. The email address is not stored after the check completes.
The password checker works differently. When a user enters a password, it is converted into a code entirely within the browser. Only the first few characters of that code are sent to the database — the full password never travels anywhere and nothing is stored. This approach, called k-anonymity, means a password can be checked for exposure without ever being transmitted in readable form.
Privacy and data handling
No user account is required to use any tool on EmailLeaked. Emails entered into the checker are not stored after the check completes. Passwords never leave the browser in readable form. Analytics are collected via Google Analytics 4 with explicit user consent only, as described in the privacy policy.
Who is behind EmailLeaked
EmailLeaked is an independent publication launched in 2026 and run by its in-house editorial team. The team sets the site's editorial standards, makes its product and privacy decisions, and reviews every tool and article for factual accuracy, source quality, and reader safety before it is published. No company can pay to change a breach result, influence a risk label, or be recommended over the alternatives. Our full process is documented in our editorial standards.
