GDPR - Deletion
If the personal data that companies or other organisations (so-called controllers) have stored on you is no longer necessary for its original purpose, you have a “right to be forgotten” according to the General Data Protection Regulation. This means that you can ask the controller to delete said data.
If the controller has forwarded your data to other companies, they also have to inform them about your request for deletion.
To delete your Personal Data, 10 days from your last reservation must pass.
