Data leak checker
Drop an email address in the box. We'll cross-reference it against known public breaches and tell you which dumps it appears in. Check yours, your partner's, your old startup's.
We hash your address and never store it. This page does not send a copy of your email to any tracking service.
What is a data breach?
A data breach is when an attacker pulls customer records out of a company's database and the dump becomes public — sold on a forum, leaked on Telegram, mirrored on Pastebin. Even small breaches usually contain emails and password hashes; large ones have phones, addresses, and sometimes plaintext passwords.
Once your address is in a dump, you'll see an uptick in spam, phishing, and credential-stuffing attempts (where attackers replay your old password against unrelated sites). The mitigation is straightforward: never reuse a password, use a manager, and turn on two-factor.
What PlanetProxy does about this
A VPN can't unbreak past breaches. What it can do is make future breaches harder to attribute to you: encrypt the traffic that goes to services in the first place, hide your real IP so attackers can't correlate accounts across sites, and — on Atlas — alert you when an address you've subscribed to monitor turns up in a new dump.
A note on this page
The full breach lookup runs server-side via the Have I Been Pwned v3 API and lands in the next deploy. The result you see here is a deterministic demo based on a hash of your address — useful for shape, not for ground truth. For a real-time lookup right now, paste your email at haveibeenpwned.com.
