Private Gmail Leak Tester

Enter your e-mail address to test if your e-mail password was leaked. There's a 4% false positive rate, so your address may appear as leaked when it's not.

For your privacy, all queries on this page are performed locally and offline, entirely within your browser. This page contains a special, compact version of the 5-million address database. Your e-mail address is not transmitted to any servers.
