GDPR Anonymization Tool
Detect and anonymize personal data in compliance with GDPR Article 4(5). 285+ entity types, 48 languages, reversible encryption. 100% EU infrastructure.
What is GDPR Anonymization?
GDPR anonymization removes or transforms personal data. After the process, the data cannot point to a specific person — even when joined with other information. Under GDPR Article 4(5), properly anonymized data falls outside the regulation's scope.
Unlike pseudonymization (which can be reversed), true anonymization is irreversible. However, many use cases require reversible anonymization (pseudonymization with encryption) to maintain data utility while protecting privacy.
anonym.legal supports both approaches: permanent redaction for true anonymization, and AES-256-GCM encryption for reversible pseudonymization that meets GDPR requirements for data protection.

Frequently Asked Questions
The EDPB is running a 2025 right-to-erasure enforcement sweep — what do we need to do?
The EDPB's coordinated enforcement action focuses on whether organizations can actually locate and delete all instances of personal data when a data subject exercises their right to erasure. anonym.legal's PII detection (285+ entity types across 48 languages) can scan your data stores to identify where personal data exists, supporting systematic erasure regulatory fit. The reversible encryption feature helps distinguish anonymized data (which falls outside GDPR scope) from pseudonymized data (which doesn't).
TikTok was fined EUR530M for sending EU data to China — how do I ensure my anonymization tool doesn't create data transfer problems?
anonym.legal's entire infrastructure is hosted in Hetzner data centers in Germany — no data ever leaves EU jurisdiction. Unlike vendors with US or Asian server infrastructure, this eliminates cross-border transfer risk entirely. Zero-knowledge architecture provides an additional layer: even within the EU infrastructure, anonym.legal cannot access your data in plaintext.
