The General Data Protection Regulation (GDPR) can be overwhelming for development teams. Learn how Juro's AI-powered scanning makes GDPR compliance accessible and automated.

Understanding GDPR Requirements​

GDPR requires organizations to protect personal data through:

  • Lawful Processing: Data must be processed lawfully, fairly, and transparently
  • Purpose Limitation: Data should only be collected for specific, legitimate purposes
  • Data Minimization: Collect only the data that is necessary
  • Accuracy: Keep personal data accurate and up to date
  • Storage Limitation: Don't keep data longer than necessary
  • Security: Implement appropriate technical and organizational measures

Common GDPR Violations in Code​

1. Unencrypted Personal Data Storage​

❌ Violation:

// Storing personal data in plain text
localStorage.setItem('userEmail', user.email);
localStorage.setItem('userPhone', user.phoneNumber);

✅ Compliant:

// Encrypt personal data before storage
const encryptedEmail = await encrypt(user.email, encryptionKey);
const encryptedPhone = await encrypt(user.phoneNumber, encryptionKey);

localStorage.setItem('userEmail', encryptedEmail);
localStorage.setItem('userPhone', encryptedPhone);

❌ Violation:

// Collecting data without explicit consent
function collectUserData() {
  const userData = {
    email: document.getElementById('email').value,
    preferences: getCookiePreferences(),
    location: getCurrentLocation()
  };
  
  sendToAnalytics(userData); // No consent check
}

✅ Compliant:

// Check for explicit consent before data collection
function collectUserData() {
  if (!hasExplicitConsent()) {
    showConsentModal();
    return;
  }
  
  const userData = {
    email: document.getElementById('email').value,
    preferences: getCookiePreferences(),
    location: getCurrentLocation()
  };
  
  sendToAnalytics(userData);
}

3. Inadequate Data Subject Rights​

❌ Violation:

// No way for users to access their data
function getUserData(userId) {
  // No implementation for data access request
  return null;
}

✅ Compliant:

// Implement data access rights
async function getUserData(userId) {
  const userData = await database.getUserData(userId);
  
  return {
    personalData: userData.personal,
    processingPurposes: userData.purposes,
    retentionPeriod: userData.retention,
    thirdPartySharing: userData.sharing
  };
}

// Implement data deletion rights
async function deleteUserData(userId) {
  await database.deleteUserData(userId);
  await analytics.deleteUserData(userId);
  await marketing.deleteUserData(userId);
}

How Juro Helps with GDPR Compliance​

Automated Violation Detection​

Juro automatically scans your code for GDPR violations:

# Scan for GDPR compliance
juro scan --path ./my-project --rules gdpr

# Get detailed GDPR report
juro scan --path ./my-project --rules gdpr --format json --output gdpr-report.json

Natural Language Queries​

Ask questions about your code's GDPR compliance:

# Ask about data handling
juro ask "Does my user registration form comply with GDPR data minimization requirements?"

# Ask about consent mechanisms
juro ask "Are there proper consent mechanisms for data collection in my analytics code?"

# Ask about data subject rights
juro ask "Is there a way for users to access and delete their personal data?"

Real-Time Feedback​

Get instant GDPR compliance feedback as you code:

// Juro will highlight this as a potential GDPR violation
const userData = {
  email: user.email, // ⚠️ Personal data without encryption
  preferences: user.preferences
};

localStorage.setItem('userData', JSON.stringify(userData)); // ⚠️ Storing personal data in localStorage

Advanced GDPR Features​

Custom Rule Creation​

Create custom GDPR rules for your specific use case:

{
  "rules": {
    "gdpr": {
      "customPatterns": [
        {
          "pattern": "localStorage\\.setItem.*personal",
          "message": "Personal data should not be stored in localStorage without encryption",
          "severity": "high"
        },
        {
          "pattern": "console\\.log.*email",
          "message": "Personal data should not be logged to console",
          "severity": "medium"
        }
      ]
    }
  }
}

Integration with CI/CD​

Automate GDPR compliance checks in your development workflow:

name: GDPR Compliance Check
on: [push, pull_request]

jobs:
  gdpr-check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Run GDPR Compliance Scan
        run: |
          juro scan --path ./src --rules gdpr --format sarif --output gdpr-results.sarif
        env:
          JURO_API_KEY: ${{ secrets.JURO_API_KEY }}
      - name: Upload SARIF results
        uses: github/codeql-action/upload-sarif@v2
        with:
          sarif_file: gdpr-results.sarif

Best Practices for GDPR Compliance​

1. Implement Privacy by Design​

// Design systems with privacy in mind
class UserDataManager {
  constructor() {
    this.encryptionKey = this.generateEncryptionKey();
    this.retentionPolicy = this.loadRetentionPolicy();
  }
  
  async storeUserData(data) {
    // Encrypt before storage
    const encryptedData = await this.encrypt(data);
    
    // Set retention period
    const expirationDate = new Date();
    expirationDate.setFullYear(expirationDate.getFullYear() + 1);
    
    await this.database.store(encryptedData, expirationDate);
  }
  
  async deleteExpiredData() {
    await this.database.deleteExpired();
  }
}

2. Use Data Classification​

// Classify data by sensitivity
const DATA_CLASSIFICATION = {
  PUBLIC: 'public',
  INTERNAL: 'internal',
  CONFIDENTIAL: 'confidential',
  RESTRICTED: 'restricted'
};

function handleUserData(data, classification) {
  switch (classification) {
    case DATA_CLASSIFICATION.RESTRICTED:
      return this.encryptAndStore(data);
    case DATA_CLASSIFICATION.CONFIDENTIAL:
      return this.encryptAndStore(data, { retention: '1year' });
    case DATA_CLASSIFICATION.INTERNAL:
      return this.storeWithAccessLog(data);
    case DATA_CLASSIFICATION.PUBLIC:
      return this.store(data);
  }
}

3. Implement Audit Logging​

// Log all data processing activities
class GDPRCompliantLogger {
  logDataAccess(userId, dataType, purpose) {
    this.auditLog.push({
      timestamp: new Date(),
      userId,
      dataType,
      purpose,
      action: 'access',
      legalBasis: this.getLegalBasis(purpose)
    });
  }
  
  logDataDeletion(userId, dataType) {
    this.auditLog.push({
      timestamp: new Date(),
      userId,
      dataType,
      action: 'deletion',
      legalBasis: 'consent_withdrawal'
    });
  }
}
