# Protect Customer Privacy When Using AI Tools

Redactli helps businesses safely use sensitive data with AI tools like ChatGPT, Claude, and analytics platforms. Encrypt PII directly in Google Sheets™ before export - no more privacy concerns.

## Why Redactli?

When businesses want to analyze customer data with AI tools, they face a dilemma:
- **Upload real data** → Risk privacy violations, GDPR fines, customer trust
- **Manually redact data** → Time-consuming, error-prone, inconsistent
- **Avoid AI entirely** → Miss out on valuable insights

**Redactli solves this**: Encrypt sensitive columns with one click, use AI safely, decrypt when needed.

## Key Features

### 🔒 Privacy-First Architecture
- Encryption happens in your spreadsheet
- Only selected column values transmitted to API
- No spreadsheet data stored on our servers
- GDPR and Privacy Act compliant

### 🎯 Smart PII Detection
Automatically detects columns containing:
- Names (first, last, full)
- Email addresses
- Phone numbers
- Street addresses
- ID numbers (SSN, passport, driver's license)
- Financial data (bank accounts, credit cards)

One-click encryption for all detected columns.

### 🔐 Military-Grade Encryption
- AES-SIV encryption (deterministic)
- Same values produce same encrypted output
- Preserves data relationships for AI analysis
- Encryption keys stored in Supabase Vault

### ↩️ Reversible Anonymization (Paid Plans)
- Decrypt data back to original values
- Essential for teams that need to "de-anonymize" after analysis
- Secure key management

## Why "Anonymization" vs "Pseudonymization"?

Technically, Redactli implements **pseudonymization** (reversible encryption). We use "anonymization" because:
- Data cannot be attributed to individuals without the encryption key
- Meets GDPR Article 4(5) definition
- More recognizable term for users
- Functionally equivalent for privacy protection

See our docs for detailed explanation.
