GDPR Compliance

Learn how Juro's deterministic, signed compliance scanner surfaces GDPR (General Data Protection Regulation) gaps in your codebase. Coverage is scoped to a defined GDPR rule pack — explicit, auditable, and not aspirational.

✅ Current Implementation Status​

Juro includes 5 GDPR Article 30 rules that are fully implemented and actively scanning your code:

Implemented Rules​

  1. Processing Activities - Personal data processing activities must be logged
  2. Controller/Processor Info - Data controller and processor information must be documented
  3. Processing Purposes - Data processing purposes must be clearly defined
  4. Retention Periods - Data retention periods must be specified
  5. Data Subject Rights - Data subject rights must be documented

Coverage Details​

  • Severity Levels: HIGH, MEDIUM
  • File Types: All programming languages (.js, .ts, .py, .java, .cs, .php, .rb, .go, .rs, .swift, .kt)
  • Context Patterns: Advanced pattern matching for actual data vs. configuration
  • Real-Time Scanning: Available in VS Code extension with instant feedback

Key Principles​

Lawfulness, Fairness, and Transparency​

  • Ensure data processing is lawful
  • Be transparent about data collection
  • Provide clear privacy notices

Purpose Limitation​

  • Collect data only for specific purposes
  • Don't use data for unrelated purposes
  • Document data processing purposes

Data Minimization​

  • Collect only necessary data
  • Avoid excessive data collection
  • Regular data audits

Common Violations​

Data Collection​

  • Collecting unnecessary personal data
  • Missing consent mechanisms
  • Inadequate privacy notices

Data Processing​

  • Processing data without legal basis
  • Inadequate data security measures
  • Missing data retention policies

Data Subject Rights​

  • Inadequate data subject access
  • Missing data portability features
  • Inadequate data deletion mechanisms

Best Practices​

Code Implementation​

// Good: Explicit consent
const consent = await getExplicitConsent(userId, purpose);

// Bad: Implicit consent
const data = collectUserData(); // No consent check

Data Security​

// Good: Encrypted data storage
const encryptedData = await encrypt(personalData);

// Bad: Plain text storage
localStorage.setItem('personalData', personalData);

Privacy by Design​

// Good: Privacy-focused design
class UserData {
  constructor(data) {
    this.encryptedData = this.encrypt(data);
    this.retentionDate = this.calculateRetentionDate();
  }
}

Juro GDPR Scanning​

Command Line Scanning​

# Scan for GDPR violations
juro scan --path ./src --rules gdpr --format json

# Scan with specific severity threshold
juro scan --path ./src --rules gdpr --severity-threshold HIGH

# Generate detailed report
juro scan --path ./src --rules gdpr --format html --output gdpr-report.html

VS Code Extension​

  • Real-Time Scanning: Violations appear instantly as you type
  • Inline Highlighting: Visual indicators for GDPR violations
  • Hover Tooltips: Detailed information and fix suggestions
  • GDPR Posture Score: Real-time 0–100 score against the loaded GDPR rule pack, with rule-pack version + scope statement always visible (see the Posture Score contract)
