Data Privacy

Secure Test Data

Scrub PII from production files client-side. Create safe datasets for testing or sharing with external consultants without server risk.

  • GDPR/HIPAA compliant masking
  • Realistic test data generation
  • Client-side processing

Standardize onboarding

Masking is a pre-processing step. Ensure your sanitized data—and your real client data—adheres to destination schemas with automated onboarding workflows.

Client-Side Processing ArchitectureSecure

Your data never leaves your device. All processing happens locally in your browser's memory via WebAssembly/JavaScript. This ensures complete data sovereignty and compliance with GDPR, HIPAA, and SOC2 standards as no files are uploaded to our servers.

Frequently Asked Questions

Is this GDPR/HIPAA compliant?

Yes. Because the anonymization happens entirely on your device (client-side), the unmasked PII never leaves your control.

Does it generate valid fake data?

Yes. Unlike simple masking (e.g., '***'), our anonymizer gives you the option to replace data with syntactically valid fake data (e.g., real-looking emails, addresses, and names). You can choose from 5 anonymization strategies. This allows you to test validation logic in downstream systems.

Is the anonymization reversible?

No. The process is destructive. Once you download the anonymized file, the original mapping is not saved, making it impossible to reverse-engineer the original identity.
