According to GDPR Art. 4 Para. 1, personal data is any information relating to an identified or identifiable natural person. This means: Any information that can be directly or indirectly attributed to a person is considered personal and subject to data protection.
What does our anonymizer detect?
We detect full names ('Michael Berg'), direct contact information (emails, phone numbers), and identifying combinations ('Franziska from Berlin'). Single first names alone ('Michael') are not detected – only the combination with location or company makes them identifying.
Our PII anonymizer meets GDPR requirements and represents the state of the art for automated PII detection.
GDPR Compliance
Art. 32 GDPR – Appropriate Technical Measures
GDPR does not require 100% detection, but rather "appropriate technical and organizational measures" taking into account the state of the art.
State of the Art
98-99% detection rate is industry standard for automated PII detection and represents the current state of the art.
There is no fixed percentage in GDPR – the standard is the proportionality of the measures employed.
Our Detection Rates
Based on internal tests and benchmarks, we achieve the following detection rates:
~99%
Names (complete)
~99.9%
Email Addresses
~98%
Phone Numbers
~97%
Addresses (DE/AT/CH)
~99.9%
IBANs
~95%
Context-based Detection
Detection rates may vary depending on text quality and format.
Residual Risk Assessment
Despite high detection rates, there is a residual risk that individual PII may not be detected:
- Unusual spellings: Very rare names, dialects, typos
- Context-dependent PII: Information that is only identifying in context
- New formats: Not yet known phone or ID formats
Risk Mitigation
- For critical documents, we recommend manual review
- Use de-anonymization to verify results
- For sensitive data: Combine with manual review
Professional Use
Our PII anonymizer is suitable for professional use:
- Documented detection rates for compliance evidence
- Transparent processing with traceable results
- GDPR-compliant architecture (Privacy by Design)
- Regular updates of detection patterns
⚠️ Note: Responsibility for correct anonymization lies with the user. We recommend verifying results for critical use cases.
Our PII anonymizer supports all 27 EU countries plus UK, USA, Switzerland, and Turkey. Detection happens automatically based on recognized patterns.

This information is not personal data:
Single First Names (without context)
Michael, Anna, Thomas (without 'I am' or location)
A first name alone does not identify a person – there are millions of people with the same first name. BUT: In patterns like 'I am Peter' or with location information they are detected.
Cities and Places
Hamburg, Berlin, Munich
Location information is public and does not identify a person.
Job Titles
Office Clerk, Software Engineer
Job titles describe a role, not a person.
Company Names
Schiller & Wolf, Google
Company names are not personal data. Exception: Companies with legal form (e.g. 'Müller GmbH') may be detected for sole proprietorships.
Our system also detects combinations that only become identifying together:
Examples of identifying combinations:
✓
Franziska from Berlin
→ First name + City
✓
Thomas works at Microsoft
→ First name + Company
✓
Anna lives in Cologne
→ First name + City
How does it work?
- SpaCy detects individual entities: people, places, organizations
- When a single first name is within 40 characters of a place or company → identifying context
- The entire phrase is anonymized as
CONTEXT_PERSON_1
