Gdpr compliance

GDPR Compliance Skill

This skill provides comprehensive guidance for implementing and reviewing GDPR-compliant features in Empathy Ledger.

GDPR Rights Reference

Article 15 - Right of Access

Requirement: Users can request a copy of their personal data

Implementation:

// GET /api/user/export
const data = await gdprService.exportUserData(userId)
// Returns: stories, media, profile, consent records, activity logs

Article 16 - Right to Rectification

Requirement: Users can correct inaccurate personal data

Implementation:

• Edit profile via profile settings
• Edit stories via story editor
• All changes logged in audit trail

Article 17 - Right to Erasure (Right to be Forgotten)

Requirement: Users can request deletion of their data

Implementation:

// POST /api/user/deletion-request
// Initiates 30-day deletion workflow

// POST /api/stories/[id]/anonymize
// Immediate anonymization of specific story

Anonymization Process:

1. Remove PII from story content
2. Replace author name with "Anonymous Storyteller"
3. Disassociate from profile (set storyteller_id = null)
4. Revoke all active distributions
5. Anonymize related media
6. Keep anonymized audit trail

Article 20 - Right to Data Portability

Requirement: Users can export data in machine-readable format

Implementation:

• JSON export format
• Includes all user-generated content
• Downloadable via vault dashboard

Consent Management

Consent Capture

interface ConsentRecord {
  has_consent: boolean           // Initial consent given
  consent_verified: boolean      // Consent verification completed
  consent_method?: string        // 'written' | 'verbal' | 'digital'
  consent_date?: Date
  consent_witness_id?: string    // For verbal consent
}

Consent Withdrawal

// POST /api/stories/[id]/consent/withdraw
// Triggers:
// 1. Set consent_withdrawn_at timestamp
// 2. Revoke all embed tokens
// 3. Mark all distributions as revoked
// 4. Send webhook notifications
// 5. Queue external takedown requests
// 6. Create audit log entries

Data Processing Lawful Bases

For Empathy Ledger, we rely on:

1. Consent (Article 6(1)(a)) - Primary basis for story sharing
2. Legitimate Interest (Article 6(1)(f)) - Platform operation, security

Data Minimization

Collect Only What's Needed

• Essential profile data: name, email, organization
• Story content: as provided by user
• Technical data: minimal logging for security

Retention Limits

• Active data: retained while account active
• Deleted data: fully removed within 30 days
• Anonymized data: kept for aggregate statistics only
• Audit logs: anonymized after account deletion

  exportUserData(userId: string): Promise<DataExport>
  anonymizeStory(storyId: string): Promise<AnonymizeResult>
  anonymizeUserData(userId: string): Promise<AnonymizeResult>
  createDeletionRequest(userId: string, type: string): Promise<Request>

Code Review for GDPR

When reviewing code, verify:

1. Data Collection: Is this data necessary?
2. Consent: Is consent captured before processing?
3. Access: Can users access their data?
4. Rectification: Can users correct their data?
5. Erasure: Can users delete their data?
6. Portability: Can users export their data?
7. Audit: Are actions logged?
8. Security: Is data properly protected?
