Why this is useful

Many people use the same email address for years. This check gives you a compact overview of places where your address may be known, without building a public profile around it.

What is an email privacy scan?

An email privacy scan checks whether your email address appears to be known by selected online sources. It can help you discover old accounts, forgotten registrations, public mentions, and services where your address may still be active.

How we protect your privacy

The scan starts only after you confirm the email address. Results are shown on a private scan page, are not published, and are not used to create a searchable profile about you.

What should you do with the result?

Use the overview as a practical signal. Review unfamiliar registrations, close accounts you no longer need, change reused passwords, and enable two-factor authentication on important services.

How does the email scan work?

1

Enter your own email address

You confirm that this is your own address and complete the security check.

2

Confirm the email we send you

The scan only starts after you click the verification link sent to that email address.

3

Review the detected registrations

After verification, you receive an overview of websites where the email address appears to be registered.

Frequently asked questions

Can I scan any email address?

No. This service is intended for your own email address, or for an address you have explicit permission to check.

Why does a scan take a little while?

We check multiple websites step by step. Some websites respond faster than others, so progress is shown during the scan.

What will I see in the result?

You only see websites where your email address appears to be registered. Treat the result as a clear indication, not legal proof.

Why is a result described as appears registered?

Websites regularly change their technical checks. Results should therefore be treated as a strong indication, not legal proof.
