• Have ≥$25M annual gross revenue, OR
• Buy/sell/share personal info of ≥100,000 CA consumers/households, OR
• Derive ≥50% of annual revenue from selling personal info

Fines: up to $2,500 per unintentional violation, $7,500 per intentional violation. California AG and individual consumers can sue.

Consumer Rights Under CCPA/CPRA

• Racial or ethnic origin
• Religious or philosophical beliefs
• Union membership
• Contents of mail, email, text messages
• Genetic data
• Biometric data used for identification
• Health information
• Sexual orientation or sex life

Data Inventory and Mapping

Before building DSR workflows, map your data:

# data_inventory.py — document what personal data you collect

DATA_INVENTORY = {
    "users": {
        "table": "users",
        "fields": {
            "email": {"category": "contact", "sensitive": False, "sold": False},
            "name": {"category": "identifier", "sensitive": False, "sold": False},
            "ip_address": {"category": "usage", "sensitive": False, "sold": False},
            "location": {"category": "location", "sensitive": True, "sold": False},
            "phone": {"category": "contact", "sensitive": False, "sold": False},
        },
        "retention_days": 365 * 3,  # 3 years
        "third_parties": ["Stripe", "SendGrid", "Mixpanel"],
    },
    "analytics_events": {
        "table": "events",
        "fields": {
            "user_id": {"category": "identifier", "sensitive": False, "sold": False},
            "event_name": {"category": "behavior", "sensitive": False, "sold": False},
            "device_id": {"category": "identifier", "sensitive": False, "sold": True},
        },
        "retention_days": 365,
        "third_parties": ["Mixpanel", "Segment"],
    }
}

Privacy Notice Requirements

Your privacy policy must disclose:

• Categories of personal information collected
• Purposes for collection
• Whether you sell or share personal information
• Categories of third parties data is disclosed to
• Consumer rights and how to exercise them
• Contact info for privacy requests

// Required sections in privacy policy
const REQUIRED_DISCLOSURES = {
  collected_categories: [
    "Identifiers (name, email, IP address)",
    "Commercial information (purchase history)",
    "Internet or other network activity (browsing history)",
    "Geolocation data",
    "Inferences drawn from above"
  ],
  collection_purposes: [
    "Provide and improve our services",
    "Send transactional and marketing emails",
    "Analytics and product development"
  ],
  sells_data: false,        // Required disclosure
  shares_data: true,        // Sharing = cross-context behavioral advertising
  shared_with: ["Google Analytics", "Facebook Pixel", "Mixpanel"],
  rights_contact: "privacy@yourcompany.com",
  opt_out_url: "https://yourcompany.com/privacy/opt-out"
};

GPC (Global Privacy Control) Signal Detection

GPC is a browser signal that automatically invokes the right to opt-out of sale/sharing. California law (CPRA) requires businesses to honor it as of 2023.

// Express.js middleware — detect GPC signal and honor opt-out
const gpcMiddleware = (req, res, next) => {
  const gpcEnabled = req.headers['sec-gpc'] === '1';
  
  if (gpcEnabled) {
    // Auto-apply opt-out for this request
    req.privacyConsent = {
      optedOutOfSale: true,
      optedOutOfSharing: true,
      source: 'gpc_signal',
      detectedAt: new Date().toISOString()
    };
    
    // Record opt-out preference
    if (req.user) {
      recordOptOut(req.user.id, 'gpc_signal');
    } else {
      // Use cookie to persist for anonymous users
      res.cookie('ccpa_optout', '1', { 
        maxAge: 365 * 24 * 60 * 60 * 1000,  // 1 year
        httpOnly: true, 
        secure: true, 
        sameSite: 'Strict'
      });
    }
  }
  
  next();
};
