/ Document anonymiser /

The contract goes to CRZ.
The personal data in it does not.

It finds names, ID numbers, addresses and signatures in your document. You confirm them and download a PDF ready for publication.

/ What to watch out for /

A contract in CRZ cannot be taken back

A published contract is public and permanent. A mistake in it cannot be undone.

+1 day

Effectiveness waits for publication

A contract takes effect the day after publication. Every hour of manual redacting delays performance.

Section 47a(1) of the Slovak Civil Code

3 months

After that the contract does not exist

If a contract is not published within three months, it is deemed never to have been concluded.

Section 47a(4) of the Slovak Civil Code

§ 5a

The responsibility is yours

The obliged entity is responsible for personal data in a published contract.

Section 5a of Act No. 211/2000 Coll.

Every day

AI bots from all over the world pull your contracts from the CRZ

The register is public, so AI tools and search engines crawl it daily. Whatever you published by mistake is downloaded before you notice — and cannot be taken back.

/ How it works /

Four steps to CRZ

No installation. Everything runs in your browser.

Step 1

You upload the contract

PDF, Word or a scan.

Step 2

The agent finds the data

Names, ID numbers, addresses, IBANs, signatures and stamps.

Step 3

You confirm the proposal

The decision stays with you.

Step 4

You publish in CRZ

A PDF with permanently removed text, plus a report.

The agent does not decide for you. It shows you what to check.

/ FAQ /

Frequently asked questions

Is the anonymised PDF truly unreadable, or just covered up?

We permanently remove the text under the blackout. It is not a black rectangle you can delete in an editor.

What if the agent misses a piece of data?

The agent proposes, you confirm. You can add anything with a drag of the mouse — a signature, a stamp, a whole paragraph.

Where is the document processed?

On servers we operate in Slovakia. We do not use the document to train models and we delete it after download.

Does Anonymizér publish the contract to CRZ directly?

We prepare the PDF and the report; publication is done by your authorised user. The portal shows what is ready and what is already published.

Can you process an archive of older contracts?

Yes, in batches. For larger volumes and records-system integration we prepare an individual quote.

How much does it really save?

Manual redaction takes 20 to 40 minutes per document. With Anonymizér it is a review that takes minutes.
