# Notion Data Handling ## Overview Handle sensitive data correctly when integrating with Notion: detect PII in page properties and block content, redact sensitive fields before logging or exporting, minimize data exposure with `filter_properties`, and implement GDPR/CCPA compliance patterns including right-of-access exports, right-of-deletion (archive or field clearing), and retention-based archival with audit logging. ## Prerequisites - `@notionhq/client` v2+ installed (`npm install @notionhq/client`) - Python alternative: `notion-client` (`pip install notion-client`) - Understanding of which Notion databases contain personal data - Audit logging infrastructure (structured logs, SIEM, or Notion audit database) - Legal guidance on applicable regulations (GDPR, CCPA, HIPAA, etc.) ## Instructions ### Step 1: PII Detection in Notion Content Notion pages can contain PII in any property type. Scan systematically: ```typescript import { Client } from '@notionhq/client'; import type { PageObjectResponse } from '@notionhq/client/build/src/api-endpoints'; const notion = new Client({ auth: process.env.NOTION_TOKEN }); // PII pattern matchers const PII_PATTERNS = [ { type: 'email', pattern: /[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g }, { type: 'phone_us', pattern: /\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/g }, { type: 'phone_intl', pattern: /\+\d{1,3}[-.\s]?\d{4,14}/g }, { type: 'ssn', pattern: /\b\d{3}-\d{2}-\d{4}\b/g }, { type: 'credit_card', pattern: /\b...
