anonym.legal — Enterprise-Grade PII Detection & Anonymization
Regex patterns for structured data, proven ML models for names. Transparent, auditable results on Hetzner's ISO 27001-certified servers in Germany. 260+ entity types, 48 languages with RTL support, MCP Server for AI tools.
Platform Overview
anonym.legal is a Zero-Knowledge PII detection and anonymization platform designed for legal professionals and privacy-conscious organizations. Features native MCP Server integration for AI tools (Claude Desktop, Cursor, VS Code via Continue and Cline) and advanced Zero-Knowledge authentication where your password never leaves your device.
What Makes anonym.legal Unique
Zero-Knowledge Authentication
Your password never leaves your device. Built with Argon2id + XChaCha20-Poly1305 encryption and AES-256-GCM vault encryption. 24-word recovery phrase for account recovery.
MCP Server for AI Tools
Native integration with Claude Desktop (stdio), Cursor, and VS Code via Continue and Cline extensions (HTTP). 6 operators: encrypt, hash, mask, redact, replace, keep. Entity groups and presets (UNIVERSAL, FINANCIAL, DACH, FRANCE, NORTH_AMERICA).
48 Languages + RTL Support
Extended language support including Arabic, Hebrew, Persian, and Urdu with right-to-left rendering. Powered by spaCy, Stanza, and XLM-RoBERTa transformers.
Legal-Focused Design
Optimized for contract anonymization, e-discovery, and FOIA compliance. Audit trails and reproducible results for legal document production.
Privacy-First AI Workflow
The MCP Server acts as a privacy shield between your AI tools and sensitive data.
- AI Tool Request — Claude Desktop, Cursor, or VS Code (via Continue/Cline) sends request containing sensitive data
- MCP Interception — MCP Server intercepts and analyzes content for PII
- PII Tokenization — Sensitive data replaced with tokens (e.g., PII_PERSON_001, PII_EMAIL_001)
- AI Processing — AI processes only anonymized information
- Response Return — Response flows back through MCP Server
- Optional De-tokenization — Original values can be restored if needed
Multi-Engine Language Processing
anonym.legal uses three NLP engines optimized for different language families with lazy-loaded models for efficiency. Regex patterns for structured data, ML models for names and organizations.
spaCy Engine
25 Languages
Fast industrial-strength NLP for European languages and major world languages.
Stanza Engine
7 Languages
Stanford NLP engine for specialized language processing and academic accuracy.
XLM-RoBERTa Transformer
16 Languages
Cross-lingual transformer for low-resource languages and multilingual documents.
PII Detection & Anonymization
260+ Entity Types
Names, emails, phone numbers, credit cards, SSNs, IBANs, IP addresses, and more. Pattern-based detection for structured data, ML-based NER for names and organizations. Confidence scoring for all detections.
5 Anonymization Methods
- Replace — Substitute with fake data
- Redact — Complete removal
- Hash — SHA-256 hashing
- Encrypt — AES-256-GCM encryption
- Mask — Partial obscuring
RTL Language Support
Full right-to-left support for Arabic, Hebrew, Persian, and Urdu. Automatic language detection for mixed-language documents.
Deterministic Results
Regex patterns for structured data give 100% reproducible results. ML-based NER provides high consistency for names. Fully auditable for compliance.

Zero-Knowledge Architecture
Password Never Leaves Device
True Zero-Knowledge authentication. Your master password is used locally to derive encryption keys. Server never sees your password.
Argon2id + XChaCha20-Poly1305
Memory-hard key derivation with modern authenticated encryption. Industry-leading cryptographic primitives.
24-Word Recovery Phrase
BIP-39 compatible recovery phrase for account recovery. No password reset emails — you control your keys.
ISO 27001:2022 Certified
Hosted in Hetzner data centers in Germany. Full GDPR compliance with EU data residency.
Transparent Token System
Think of tokens like game coins. Each operation costs tokens based on text length, entities detected, and operations applied. AI Entity Creation costs 50 tokens per request.
