# Missing Data Retention Policy Implementation

## Overview
GDPR Article 5(1)(e) requires data to be kept no longer than necessary. Storing user data indefinitely without purging mechanisms violates the storage limitation principle.

Common issues:
- Log files without rotation or TTL
- Database records never deleted
- Caches that accumulate PII indefinitely
- Backups stored without expiration

## Remediation
- Implement automated data purging for records beyond retention period
- Set TTL on Redis/Memcached keys containing personal data
- Configure log rotation with appropriate retention
- Document and enforce data retention policy
