2.2 Some services, such as user profiles, linking profiles to ORCID, DOI-based publication of content require a registration (Registered Users).

2.8 TIB will terminate accounts at the request of the user in text form at any time and without undue delay. All personal data in the user profile will be deleted without undue delay.
