When & Why to Use This Skill

This Claude skill provides a robust framework for implementing PII handling, data retention, and GDPR/CCPA compliance within Supabase integrations. It streamlines sensitive data management through automated classification, regex-based PII detection, and secure redaction patterns, ensuring your database operations meet global privacy standards and security best practices.

Use Cases

  • Regulatory Compliance: Automating GDPR and CCPA workflows by implementing data redaction and retention policies within Supabase environments.
  • PII Detection and Masking: Identifying and protecting sensitive user information such as emails, phone numbers, and credit card data through automated regex scanning before storage.
  • Data Lifecycle Management: Configuring automated cleanup and archiving schedules to ensure data is only stored for as long as legally or operationally necessary.
  • Security Auditing and Classification: Categorizing database fields into PII, Sensitive, or Public tiers to apply appropriate encryption and access controls for audit readiness.

Supabase Data Handling

Overview

Handle sensitive data correctly when integrating with Supabase.

Prerequisites

  • Understanding of GDPR/CCPA requirements
  • Supabase SDK with data export capabilities
  • Database for audit logging
  • Scheduled job infrastructure for cleanup

Data Classification

Category Examples Handling
PII Email, name, phone Encrypt, minimize
Sensitive API keys, tokens Never log, rotate
Business Usage metrics Aggregate when possible
Public Product names Standard handling

PII Detection

const PII_PATTERNS = [
  { type: 'email', regex: /[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g },
  { type: 'phone', regex: /\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/g },
  { type: 'ssn', regex: /\b\d{3}-\d{2}-\d{4}\b/g },
  { type: 'credit_card', regex: /\b\d{4}[- ]?\d{4}[- ]?\d{4}[- ]?\d{4}\b/g },
];

function detectPII(text: string): { type: string; match: string }[] {
  const findings: { type: string; match: string }[] = [];

  for (const pattern of PII_PATTERNS) {
    const matches = text.matchAll(pattern.regex);
    for (const match of matches) {
