Built for teams that handle sensitive documents daily
DataCleanFlow is not a generic redaction tool. It is purpose-built for European businesses that need to anonymize documents reliably, quickly, and in full compliance with GDPR.
Context-preserving replacement
We don't just black out text. Personal data is replaced with descriptive tokens like [PERSON], [EMAIL], [CPR_NUMBER] — so the document stays readable and useful for further processing.
All major file formats
Upload PDF, Word (.docx), Excel (.xlsx), CSV, JSON, plain text, and images. Download the anonymized file in the same format — no manual conversion needed.
Seconds, not hours
A 10-page document is processed in under 30 seconds. Bulk upload hundreds of files and let them process in the background. No more days of manual redaction work.
European PII formats
Purpose-built for European data: Danish CPR, Swedish personnummer, Norwegian fodselsnummer, German Steuer-ID, and more. Works across multiple European languages.
Compliance audit reports
Every anonymization job generates a detailed report: what was detected, what was replaced, and how many PII entities were found. Ready for your DPO or compliance audit.
Unlimited team members
One subscription covers your entire team. No per-seat pricing, no hidden charges. Everyone who needs to anonymize documents can do so under one account.
Security is not a feature. It is the foundation.
You are trusting us with your most sensitive documents. Here is exactly how we protect them — no marketing fluff, just facts.
European-hosted AI processing
Your documents are processed by AI running entirely within EU data centers. No data is sent to US-based cloud providers or third-party AI services. Processing happens in-memory within European infrastructure.
Zero data retention
Files are processed in memory and permanently deleted the moment you download your result. We do not store, log, or train on your documents. Ever. There is nothing to breach because we keep nothing.
End-to-end encryption
TLS 1.3 encryption for all data in transit. AES-256 encryption at rest. Your documents are encrypted from the moment they leave your browser until the moment the anonymized result arrives back.
GDPR compliant by design
UK-registered company (Vertex Digital Group Ltd) with EU-based infrastructure. We sign Data Processing Agreements with all business customers. Full audit trail for every job.

If your team handles documents containing personal data — and you share, store, or process those documents — you are legally required to protect that data under GDPR.

Read moreWhat happens when you don't anonymize?
The risks are real, immediate, and expensive.
GDPR fines up to 4% of annual revenue
Regulators in the EU issued over 2 billion EUR in GDPR fines in 2024 alone (GDPR Enforcement Tracker).
Data breach liability
Sharing un-anonymized documents with third parties creates legal liability for your organization.
Manual redaction takes hours
A single 50-page document can take 2-4 hours to manually review and redact. DataCleanFlow does it in seconds.
Human error is inevitable
Manual redaction typically misses 5-15% of personal data according to ENISA research on data protection techniques. AI catches what humans overlook.
