To implement real-time personalization while complying with GDPR, companies need to ensure that user consent is obtained and that users can control their data. Key practices include:

• Implement transparent consent management systems, ensuring users are aware of data collection and usage
• Anonymize or pseudonymize personal data where necessary, ensuring that identifiable data is not exposed
• Allow users to request data deletion and provide opt-out options
