Customer Data Protection
anonym.marketing vs Redact PDF AI — Data Protection

Why Choose anonym.marketing
- Pseudonymization preserves analytics — anonymized CRM data retains statistical value for marketing analysis. Redact PDF AI's pixel burn destroys data permanently

- 10x cheaper — Free tier with 200 tokens/month, Basic at €3/mo. Redact PDF AI starts at $50/month
- CCPA + LGPD detection — region-specific entity types for California and Brazilian compliance
