In your position at NMH, it may be the case that you are required to use various IT services to carry out your job. These IT services themselves store personal data about you. This is entirely dependent on what the service does and what function you have at NMH.
Many of these services have a user profile for you to ensure that you have authorised access to the system. Some services will also be able to log your activities for a variety of reasons, such as considerations related to security, operations or service development.
You yourself know best which services you use in your everyday activities and can contact the IT services to find out how these services/systems process your personal data.
Personal data about you will be stored where you have logged in with your NMH user name or where you are registered as an employee at NMH.
