No, this is not allowed. You can volunteer the information if you want, but your employer is not allowed to register it. Only the occupational health and safety service or company doctor may request and store your medical data.

However, your employer is allowed to request data that are necessary to assess how it must proceed with your duties. For example, when you expect to be back at work and whether there are current appointments that require action.

If you have called in sick, you may receive a questionnaire from the occupational health and safety service or company doctor, asking for medical information. You are obliged to complete this questionnaire.

The occupational health and safety service or company doctor is not allowed to transfer the completed questionnaire to your employer, not even if you give consent for this. The occupational health and safety service or company doctor may only pass on information about you to your employer that is required by the latter. Examples include the expected duration of your illness and your limitations and capabilities.

Your employer may also not directly ask you to complete a questionnaire requesting medical data. Not even with your consent.

Your employer is not allowed to do this, but it can ask the occupational health and safety service or company doctor. However, your employer is not allowed to invade your privacy more than necessary.

For example, your employer may require that you come to the surgery of the occupational health and safety service or company doctor (if you are able to do so), but it cannot demand that you stay at home all day. See also: Checking whether the employee is sick.

No, this is not allowed. Your employer may give you a wearable as a gift, such as a smartwatch, so that you can get started on improving your fitness yourself. But your employer may not gain insight into the information from your wearable, such as your number of steps, heart rate, calories burned and sleeping patterns.

This concerns data about your health. Your employer is not allowed to have this information, not even if you give consent for this. Only if you wish, you can share your data or compare them with the data of colleagues who also wear a wearable.
