When Matomo Might Be Better
Frequently Asked Questions
Is Matomo a PII anonymization tool?
No. Matomo is a web analytics platform (like Google Analytics). It has IP anonymization for visitor privacy, but it doesn't detect or anonymize PII in documents or text. For document PII protection, you need a tool like anonym.legal.
Can Matomo detect names or credit cards in my documents?
No. Matomo tracks website visitor behavior (pageviews, conversions, traffic sources). It doesn't analyze document content. For detecting and anonymizing PII in text, use anonym.legal's 285+ entity recognizers.
Do I need both Matomo and anonym.legal?
It depends on your needs. If you want privacy-compliant website analytics, use Matomo. If you need to protect PII in documents before sharing or AI processing, use anonym.legal. Many organizations use both for complete privacy coverage.
Is Matomo free?
Matomo On-Premise (self-hosted) is free and open source. Matomo Cloud starts at $23/month. anonym.legal offers a free tier with 200 tokens, then paid plans from €3/month.
Which tool is better for GDPR compliance?
Both support GDPR but for different purposes. Matomo helps with GDPR-compliant visitor tracking without US data transfers. anonym.legal helps with GDPR Article 4(5) pseudonymization and data subject request handling through reversible encryption.
Does anonym.legal offer zero-knowledge authentication?
Yes. anonym.legal uses zero-knowledge authentication with Argon2id and HKDF. Your password is processed on your device — only a mathematical proof is sent to the server, never the actual password.
Need Document PII Protection?
Matomo protects visitor analytics. anonym.legal protects your documents. Try anonym.legal free for text PII detection and anonymization.
