If your name is in the phone book, a single search yields street, house number and town. Address publishers buy exactly these directories – that is where your junk mail comes from.
Your data. Your overview.
Who knows what about you?
Name, address, phone number, leaked passwords – much of this is publicly available without you ever having consented. Find out in one minute what is circulating about you.
Free Initial check: e-mail address, name and phone number. No minimum term, no payment details.
No minimum term in the Initial check Servers located in Germany Every step with proof
One clear process instead of separate tools.
The reality check
This is what a stranger can find about you today – in under five minutes.
No sign-in, no special knowledge, using freely accessible sources alone.
Reverse lookup turns the path around: a number becomes a person with an address in seconds. Mobile numbers also end up in such directories.
Billions of login credentials from data leaks are freely available online. Anyone who knows your old password will try it again at your bank, shop and mailbox.
Name, address and date of birth are enough for orders on account, contract conclusions and redirected parcels – in your name.
Fax and postal offers
We make sure you are no longer contacted.
Do not sign anything – send it to us. We object to the advertising, have you removed from the list and re-check. From then on, your fax machine and letterbox stay quiet.
Alleged proof copies, entry confirmations and register forms look like an invoice that just needs signing off. In many cases, whoever signs enters into a multi-year contract worth several hundred to several thousand euros – for a directory entry nobody looks for. You do not have to deal with it: upload the document, we take care of the rest.

Objection to advertising, origin request and erasure from the mailing list

Check e-mail addresses and passwords against known data breaches. Your password never leaves your device: the browser computes a hash and queries only its first five characters (k-anonymity) – the comparison happens locally.

Was Sie vorab wissen sollten.
I have received a fax offer that looks like an invoice – what should I do?
Do not sign and do not fax it back. Such proof copies and entry offers turn into an often multi-year, expensive contract once signed. Upload the document to us: we record the sender, object to further advertising, ask where your data came from, demand erasure from the advertising list and re-check whether you are contacted again. If you have already signed, a review by a lawyer is also advisable – we do not provide legal advice.
What does the Zentrale Datenschutzstelle do for me?
We record findings about you with source and risk classification, check e-mail addresses against known data leaks, file access, objection and erasure requests and document every step in a traceable way.
Can you guarantee that my data will be erased?
No, nobody can guarantee erasure, because it depends on the respective other party. We take over research, technical checks, case handling, monitoring and documentation – and provide traceable proof of every step.
How do I find out where my data is listed on the internet?
After registering, you store a name, e-mail address or domain. We record findings with source, data categories, risk classification and status, and check e-mail addresses against known data leaks.
What does the Initial check cost?
The initial check is free, with no minimum term and no payment details. It shows a first status overview with a limited findings check. After that, you decide for yourself whether to book a package.
Where is my data processed?
Exclusively on servers in Germany (EU). Transfers are encrypted, and sensitive fields are additionally stored encrypted. Details can be found in the privacy policy.
